There are many kinds of alum stone, among which potassium aluminum sulfate octahydrate, commonly known as alum, is a common thing. Its physical properties are quite unique, let me come one by one.
Looking at its shape, under normal conditions, it is colorless and transparent bulk crystalline or crystalline powder, like ice crystals, crystal clear, refracted under light, delicate and uniform.
To touch it, the texture is relatively brittle, fragile when hit, smooth in section, dry to the touch, less sticky.
Smell its taste, alum has no special smell, placed under the nose to smell, only the air is fresh, no pungent, fragrant and other odors, very pure.
In terms of its solubility, soluble in water, when thrown into water, gradually melt in it, making the water slightly clear, but its aqueous solution is acidic, try it with a test strip, you can see the color change of the test strip. And in hot water, it dissolves more quickly, just like ice and snow meet the warm sun, disappearing instantaneously.
In addition, its melting point is about 92.5 ° C. When the temperature rises to this point, the original solid aluminium stone gradually turns into a liquid state, and the shape change is very wonderful.
Its density is about 1.757g/cm ³. When held in the hand, it has a certain texture. Compared with ordinary light objects, it is slightly heavy, and it can be felt that it is dense inside.
Aluminum sulfate potassium octahydrate is very useful in both life and industry, but its unique physical properties lay the foundation for its effectiveness, which is a wonderful substance.

What are the effects of sulfur hexafluoride on the environment?

"Tiangong Kaiwu" says: "All lime is refined by fire." Among them, the impact of lime on the environment is quite complicated.
Lime, that is, calcium carbonate is calcined to form calcium oxide. In ancient times, it was mostly used in construction, and it was mixed with water to form lime slurry, which can be used as a wall adhesive, which is strong and durable. However, its preparation process requires high temperature calcination of limestone, which consumes a lot of fuel, such as firewood, etc., resulting in deforestation, affecting vegetation, and then causing soil erosion.
And lime is also used in agriculture. Appropriate application to soil can adjust soil pH, improve soil structure, and benefit crop growth. However, if applied improperly, excessive lime will cause soil alkalinity to be too strong, which will damage soil fertility, affect microbial activities, and destroy soil ecological balance.
Furthermore, lime is also useful in industrial wastewater treatment and other fields, which can precipitate pollutants such as heavy metals and purify water quality. However, if the treatment process is not properly operated, it may cause secondary pollution.
The impact of lime on the environment, advantages and disadvantages coexist. Reasonable use can benefit people, such as building houses and roads, improving soil; if used improperly, it is prone to disasters, destroying mountains and forests, causing acid and alkali chaos, and causing pollution. Although the ancients did not fully examine its environmental impact, they should carefully weigh the use of lime, so as to achieve a situation where the advantages outweigh the disadvantages.

What is the role of sulfur hexafluoride in electrical equipment?

Sulfur hexafluoride is of great use in electrical appliances. Its properties are very stable, and it has excellent insulation and arc extinguishing capabilities, so it is widely used in electrical appliances.
It belongs to Guanfu electrical switches, and sulfur hexafluoride is filled in it, which can quickly extinguish the arc. When the circuit is turned on and off, there is often an arc, which is high temperature and can damage the part of the switch. Sulfur hexafluoride can decompose when it encounters an arc, absorb its energy, and quickly reduce the temperature of the arc, so that it can be extinguished quickly, ensuring the safety of the switch and protecting the stability of the circuit, so that it can be repeatedly opened and closed with less damage.
And in high-voltage electrical equipment, such as transformers, transformers, etc., sulfur hexafluoride is an excellent insulating medium. It can isolate electricity, so that the charged parts do not interfere with each other, preventing leakage and short circuits. With its strong insulation, the equipment can be compact and set up, saving the area of land and improving its operation efficiency.
Furthermore, sulfur hexafluoride has excellent thermal conductivity. When electrical equipment is running, heat will be generated, and sulfur hexafluoride can dissipate its heat, ensuring that the temperature of each part of the equipment is in the appropriate area, avoiding heat damage and prolonging the life of the equipment.
From this perspective, sulfur hexafluoride is indispensable for electrical appliances. Its power of extinguishing arcs, insulation, and heat dissipation, protecting the stability of electrical equipment, and promoting the smooth transmission of electricity, is of great significance in today's electrical field.

What are the preparation methods of sulfur hexafluoride?

The method of its preparation has many records in ancient books, and each method has its own subtlety.
One method is to extract natural aluminite, which is mostly produced in valley caves. It is better to choose the one with white and pure color and firm and brittle texture. First, clean it with water to remove its mud impurities. Then, put the aluminite in a crucible and calcine it with fierce fire. This fire needs to be made of charcoal fire, which is uniform and strong. When the aluminite is burned until it is red, the texture is crisp, take it out and cool. Then use pestles and sockets to grind it into a fine powder, which is the initially prepared aluminite powder. The aluminium stone obtained by this method has a strong dryness and is mostly used for external treatment such as sores and swelling, which can dry and wet to detoxify and converge the sores.
The second method is the method of flying with water. First, the aluminium stone is calcined according to the previous method and then ground. Then, put it in a milk bowl, add an appropriate amount of water, and grind it vigorously. At this time, the fine powder of aluminium stone is mixed with water to form a milky state. Then, pour this emulsion into a container and wait for it to settle. Pour the water on the upper layer, remove the lower layer of precipitation, and then add water to grind and precipitate, and so on. The water on the upper layer is almost clear, and the fine powder of alum stone is suspended. Finally, the resulting precipitation is dried, and the resulting aluminium stone powder is extremely fine and pure. This method can be used to obtain aluminite, which is slightly slower in nature, and can be used for internal administration of agents such as reducing phlegm and antidiarrhea. Because of its fine texture, it is easy to absorb and reduces the irritation to the stomach.
The third method can be combined with other drugs. If it is prepared with licorice and other medicines, first decoct licorice, remove the residue and extract the juice. Then, put the aluminite in licorice juice and soak it for several days. During this period, it needs to be stirred daily to make the aluminite fully absorb the medicinal power of licorice juice. After soaking, take out the aluminite, and calcine and grind it before making a powder. The aluminium stone obtained in this way, with the sweetness of licorice, eases its dryness, and adds the effect of reconciling various medicines and detoxification. It is mostly used in some complex prescriptions, which can cooperate with other medicines, enhance the curative effect, and make the medicinal properties more peaceful.
