Preparation Method

The method of making Barium Difluoride, the first raw material. Based on barium salt and fluoride, barium salt often takes pure barium carbonate, and fluoride is preferably hydrofluoric acid. The preparation process first makes the barium carbonate and hydrofluoric acid phase and put it in the reactor. Add it slowly, control its rate, and do not make it violent. During the reaction, the temperature needs to be adjusted to maintain a suitable value, about sixty to five degrees. When the two meet, gradually react, barium carbonate dissolves to release carbon dioxide, and combines with hydrofluoric acid to form Barium Difluoride. After the reaction is completed, let it stand and precipitate. Then filter it, remove its clear liquid, and wash it with water several times to remove its impurities. After the drying process, the oven is placed, the temperature is controlled at a hundred and twenty degrees, and when it dries, the pure Barium Difluoride product can be obtained. The transformation mechanism is the principle of ionization, and barium ions and fluoride ions are attracted and aggregated to form the structure of this substance.

What are the main uses of barium difluoride?

Iron disulfide, commonly known as fool gold, has three main uses.
First, it is used for ironmaking. "Tiangong Kaiwu" says: "Where there is an iron field, its iron shallow floating soil surface does not produce deep holes; it produces flat sun, but does not produce mountains." Iron disulfide can be smelted through various processes such as calcination and reduction. For example, in a furnace, iron disulfide is decomposed by heat, sulfur escapes, and iron is retained. After interacting with a reducing agent, iron is reduced and produced. It is an important raw material for ironmaking.
Second, the production of sulfuric acid. Although the book does not describe the production method of sulfuric acid in detail, according to today's chemical knowledge, iron disulfide can be calcined to obtain sulfur dioxide, sulfur dioxide is then catalyzed to oxidize to sulfur trioxide, and sulfur trioxide is combined with water to form sulfuric acid. Sulfuric acid is widely used in many industrial fields, such as metallurgy, chemical industry, pharmaceuticals, etc., which is also one of the important uses of iron disulfide.
Third, it is also valuable for geological research. Although this is not mentioned in "Tiangong Kaiwu", the distribution and morphology of iron disulfide can provide clues for geologists to study stratigraphic structure and paleoenvironmental changes. Its formation is closely related to geological conditions, so it can be used to gain insight into past geological evolution.

What are the physical properties of barium difluoride?

Iron disulfide, also known as pyrite, its mineralogy is called pyrite, commonly known as fool's gold. This is a common sulfide mineral that is produced in various geological environments. The following details the physical properties of iron disulfide:
1. ** Morphology **: The common crystal forms of iron disulfide are cubes, pentagonal dodecahedrons, and also octahedrons and rhombus dodecahedrons. Aggregates are often dense, granular or nodule-like. As in some veins, it can be seen that the cube crystal shape is intact, with a flat crystal surface and a metallic luster.
2. ** Color and streaks **: The fresh surface is light brass color, bright color, and resembles gold, which is also the reason for its name fool's gold. And its streak color is green-black, which is significantly different from the surface color, so it can be distinguished from real gold. Scratch iron disulfide with a porcelain plate to get green-black streaks.
3. ** Luster and Transparency **: It has a metallic luster and is dazzling, just like the light reflected on the metal surface. Because it is an opaque mineral, light cannot penetrate, and it is solid in appearance.
4. ** Hardness **: The Mohs hardness is about 6-6.5, which is relatively high. It can be used to carve minerals with low hardness such as calcite and gypsum, without easily leaving scratches on its own surface.
5. ** Cleavage and Fracture **: The cleavage is incomplete and it is extremely difficult to cleave in a specific direction. The fracture is jagged, uneven, uneven and smooth.
6. ** Density **: The density is relatively large, about 4.9 - 5.2g/cm ³, when held in the hand, it feels obviously heavy, and the density is higher than that of common rocks.

What are the chemical properties of barium difluoride?

Iron disulfide, commonly known as pyrite, is often mistaken for gold because of its yellow color, so it is also known as "fool's gold". It has many unique chemical properties, which are unique between heaven and earth.
Iron disulfide has strong reducing properties. In the air, it is easy to react with oxygen when heated, just like fire meets dry wood, igniting a violent change. In this reaction, iron disulfide is like a generous devotee, surrendering its own electrons to oxygen, and turning itself into iron oxide and sulfur dioxide. This process is like a game between elements. The transfer of electrons reshapes the form of matter. Sulfur dioxide escapes into the air, and iron oxide remains. The past pyrite has been transformed.
When it meets an acid, it can also cause a wonderful change. Take hydrochloric acid as an example, the two meet, just like old friends reuniting and like opponents fighting. The sulfur in iron disulfide is not willing to be reconciled with the original state and wants to break free, so it interacts with the hydrogen ions in hydrochloric acid to produce hydrogen sulfide gas. The smell of hydrogen sulfide is as bad as rotten eggs, and it makes people smell. During this process, the structure of the substance is remodeled, and new compounds are born in the furnace of chemical reactions.
Iron disulfide often acts as a reducing agent in redox reactions. Because its sulfur is in a lower valence state, it is like a latent soldier, ready to donate electrons at any time to enhance its own value state. In many chemical production scenarios, this property is cleverly used to assist in the extraction of certain elements or to promote a critical reaction, playing an indispensable role in the industrial arena. Although it is small, it is crucial, silently driving the giant wheel of the chemical industry forward.

What are the precautions in the preparation of barium difluoride?

For lead disulfide, many matters must be paid attention to when preparing.
The first item is the selection of raw materials, which must be pure. The presence of impurities may cause the product to be impure and the preparation work will be damaged. If the source of lead is selected, the pure one will be selected, and the lead containing impurities will change the properties of lead disulfide and make it unusable. The same is true for the selection of sulfur. Only when it is pure and free of impurities can it be a good basis for preparation.
The second time is the reaction condition, which is the key. Temperature is an item that must be precisely controlled. If the temperature is too low, the reaction will be slow or incomplete; if the temperature is too high, the sulfur will be volatile and the reaction will be unbalanced. It is advisable to find a suitable temperature range to The pressure should not be ignored either. Appropriate pressure allows the reaction to proceed in a positive direction. If the pressure is improper, or side reactions occur, the quality of the product will be damaged.
Furthermore, the reaction environment is also exquisite. Air intervention, or lead oxidation, can damage the reaction process. Therefore, the preparation is suitable for anaerobic or low-oxygen environments, and can be protected by inert gas to create a suitable atmosphere.
In addition, the cleanliness and corrosion resistance of the reaction equipment are also important. Unclean equipment introduces impurities; those who are not corrosion-resistant will be eroded by sulfur and lead, causing damage to the equipment and contaminating the product.
When operating, the action should be slow and stable. The addition of the drug should be done slowly to make the reaction smooth and avoid sudden and violent reactions, which will cause danger. The speed of stirring should also be moderate. If it is too fast or too slow, it is not conducive to uniform and sufficient reaction.
In the end, the separation and purification of the product also need to be fine. The preparation of lead disulfide is complete, or it contains unreacted raw materials, by-products, etc. Appropriate separation methods, such as filtration, distillation, and extraction, can obtain pure lead disulfide, which is in line with the original intention of preparation.
Preparation of lead disulfide, all details must be carefully treated, and one ring is missing, or the whole plate is lost, so as to be fine and rigorous.
