What are the main uses of Aluminum Sodium Fluoride?
Aluminum (Aluminum), sodium (Sodium) and sodium fluoride (Sodium Fluoride) have their own uses and are related to people's livelihood.
Aluminum is light in weight, electrically conductive, thermally conductive and corrosion resistant. In ancient times, although it was difficult to be widely used as it is today, imagine that if you were to build a palace pavilion, you could use it to create exquisite parts. Because of its light weight, it is easy to handle and place, and it is resistant to corrosion, it can last for a long time. In weapon casting, or you can make light and tough armor blades to help soldiers fight. In addition, if you are a court craftsman, you can cast it into beautiful utensils, such as lamps and ornaments, to show the noble spirit of the royal family. The chemical activity of sodium is lively, but it may be difficult to use it directly at that time. However, as we know today, sodium and its compounds can be used as reducing agents in the metallurgical industry. If the ancients knew this, they could be used to extract rare metals for treasure or for building artifacts.
Sodium fluoride has the ability to prevent caries. If the ancients could observe it, it could be used in the oral health of the royal family and nobles, or it could be made into a gargle to protect their white teeth. And it is also effective in wood preservative. If the pillars of the court and the shelves of books are treated with sodium fluoride, they can be preserved for a long time without corrosion, so that cultural classics and architectural treasures can be passed down for a long time.
Although it is a reverie, if these things are used in ancient times, they will definitely add luster to the civilization of China, and have the potential to change in architecture, military, and life.
What are the Physical and Chemical Properties of Aluminum Sodium Fluoride
Aluminum, sodium, and sodium fluoride are all common chemical substances in the world, each with its own unique physical and chemical properties.
Aluminum is light in texture, has a silver-white luster, and has good ductility. It can be easily made into thin sheets or drawn into filaments. Its conductivity is also excellent, and it is often used in the electrical field. And aluminum has good thermal conductivity and is widely used in the manufacture of cookware. It has active chemical properties and is easy to combine with oxygen in the air. A dense alumina film is formed on the surface. This film can prevent further oxidation of aluminum, making it resistant to corrosion. In case of strong acid or alkali, it can react and replace hydrogen.
Sodium is a silver-white metal with a soft texture and can be cut with a knife. Its density is less than that of water and its melting point is also low. The chemical properties are extremely active, and it reacts violently with oxygen in the air at room temperature, so it needs to be stored in kerosene to isolate the air. In contact with water, it reacts violently, generating sodium hydroxide and hydrogen, and at the same time releases a lot of heat, causing the generated hydrogen to burn, which is quite violent.
Sodium fluoride is a white crystalline powder with a slightly bitter taste. Its melting point is quite high, it has a certain water solubility, and the aqueous solution is alkaline. Sodium fluoride has relatively stable chemical properties and is widely used in industrial fields, such as wood preservatives, ceramic fluxes, etc.
These three have significant differences in physical and chemical properties and play an important role in different fields, providing assistance for industrial production, daily life and many other aspects.
What is the Production Method of Aluminum Sodium Fluoride?
To make sodium aluminum fluoride, the method is as follows:
Prepare raw materials, aluminum, light and strong, often in ores, and should be refined by an appropriate method. Sodium, active metals, are mostly found in the world in the form of salts, and need to go through complicated steps to obtain them. Fluoride, commonly found in fluorite and other minerals, also requires technical expertise.
Preparation of sodium aluminum fluoride, often by chemical synthesis. In a special reaction vessel, control its temperature and pressure conditions. Add aluminum powder, sodium compounds and fluoride in a certain proportion. During the reaction, various substances interact and chemical bonds break and recombine.
During this period, temperature control is the key. If it is too high, the reaction will be too fast or cause an accident; if it is too low, the reaction will be slow and time-consuming. The pressure also needs to be adapted, and the reaction can be smoother under suitable pressure.
After the reaction is completed, the product may contain impurities, so purification is required. The impurities can be removed by filtration, crystallization, distillation, etc., so that the sodium aluminum fluoride can be purified.
During this process, the operator must strictly abide by the procedures to prevent accidents. The equipment used also needs to be precise and clean to ensure the quality of the product. In this way, qualified sodium aluminum fluoride can be obtained.
What are the precautions of Aluminum Sodium Fluoride during use?
The mixture of aluminum, sodium and sodium fluoride, when used, has all kinds of things to pay attention to and needs to be careful.
First of all, its physical properties and chemical properties should be clearly understood. Aluminum has good electrical conductivity, thermal conductivity and ductility, and is prone to reaction in case of acid and alkali. Sodium is extremely active, and it ignites violently in case of water, and it is also easy to combine with oxygen. Sodium fluoride is a toxic salt that can slowly hydrolyze in air. When these three are used together, its characteristics must be well known to prevent accidents.
Furthermore, it is related to the operating environment. It should be applied in a well-ventilated place to prevent gas accumulation. Because sodium meets water or moisture, hydrogen can be generated. This is a flammable gas. If it accumulates too much, it may explode when exposed to open flames or static electricity. And hydrogen fluoride gas produced by the hydrolysis of sodium fluoride is corrosive and toxic, which is very harmful.
When operating, protective measures are indispensable. Protective clothing, protective gloves and goggles are necessary to prevent contact and injury. When taking sodium, use forceps, never hands, because it is lively and can burn when touching the skin. Aluminum and sodium fluoride should also be handled with care to avoid dust inhalation or contact with the skin and eyes.
In addition, attention should also be paid to storage. The three should be stored separately. Sodium should be stored in kerosene or paraffin oil to isolate air and water. Aluminum should be kept in a dry place to prevent oxidation. Sodium fluoride needs to be sealed and stored away from water and acid, because acid can produce highly toxic hydrogen fluoride gas.
Furthermore, waste after use must be properly disposed of in accordance with regulations. Do not discard at will to prevent pollution of the environment and endanger humans and animals.
In general, in the process of using aluminum, sodium and sodium fluoride, when following the operating procedures and paying attention to safety, we can ensure that everything goes smoothly and avoid disasters.
What is the market price range of Aluminum Sodium Fluoride?
The price range of aluminum, sodium, and sodium fluoride is available today. For aluminum, the price often varies depending on factors such as market conditions, purity, and form. For common industrial aluminum, the price per metric ton is about $1,800 to $3,000. If its purity is high, or if it has a special form, it is used in high-end manufacturing, the price is higher.
Sodium is difficult to produce because of its chemically active properties. The price of sodium ranges from about $10 to $50 per kilogram. This also varies with its purity and market supply and demand. If it is used in special scientific research or high-end industrial fields, the price also rises.
For sodium fluoride, the price is about $1,000 to $3,000 per metric ton. The price is affected by the cost of raw materials, production process, and market demand. When the demand in metallurgy, chemical and other industries is large, the price may rise; if the raw materials are easily available and the process is advanced, the price may decline.
This is a rough price. The market is volatile and the price is also variable. The actual price should be carefully studied according to the time and transaction situation.
