Description of Aluminium Diboride Powder ：
Aluminum diboride is a very stable inorganic compound with the formula AlB2, where the atomic ratio of aluminum to boron is 1:2.
Aluminum diboride has a high melting point and a relatively high density. It will begin to melt at more than 2000 ° C, and at normal pressure, its melting point is as high as about 2200 ° C. Its density is about 3.6g/cm3, similar to that of ordinary metals and intermetallic compounds.
This compound's crystal structure is hexagonal, similar to other borides, such as magnesium diboride. This structure makes aluminum diboride have good electrical and thermal conductivity, and its resistivity and thermal conductivity are similar to copper's.
In addition, aluminum diboride has good corrosion resistance. It is not attacked by alkali and various acids and does not react even in hydrofluoric acid and aqua regia. It can suffer temperatures of up to 600 ° C in an oxygen layer, while in nitrogen, it can be used at temperatures up to about 800 ° C.
In terms of application, aluminum diboride is widely used in high-temperature stoves, electronic devices, aerospace, and other fields because of its high melting point, high density, good electrical conductivity, and corrosion resistance. It is also an important raw material for synthesizing other aluminum-boron compounds.

Production Method of Aluminium Diboride Powder ：
The thermal-chemical method directly synthesizes aluminum diboride by chemical reaction under high temperature and pressure conditions. The specific production steps are as follows:
(1) Aluminum powder and boron powder are mixed to make an aluminum-boron preform with a certain shape and size.
(2) Put the prefabricated body into the furnace for a high-temperature synthesis reaction. Under high temperature and pressure conditions, aluminum and boron undergo a chemical reaction to form aluminum diboride.
(3) The required aluminum diboride products are prepared by grinding, pressing, forming, or sintering.
The thermal-chemical method has lower production costs and less waste generation. Still, it requires high-temperature and high-pressure equipment and requires higher equipment maintenance and safety requirements. In addition, the reaction conditions of the thermal-chemical method are relatively complex, and it is necessary to accurately control temperature, pressure, and other parameters to obtain high-purity and high-quality aluminum diboride products.
Electrolysis is a common method for producing aluminum diboride. The principle of this method is to generate aluminum diboride on the cathode by electrolytic aluminum and boron compound solution. The specific production steps are as follows:
(1) Preparation of electrolyte solutions containing aluminum and boron: dissolve aluminum salts and borates in appropriate solvents, such as glacial acetic acid, ethanol, etc.
(2) The electrolyte solution is sealed in the electrolytic cell, and appropriate electrolytes and additives are added to maintain the required pH value and current density.
(3) The electrolytic cell is electrolyzed, generating aluminum diboride on the cathode.
(4) The generated aluminum diboride is separated from the electrolyte solution by centrifugation, washing, and drying.
(5) Finally, the required aluminum diboride products are prepared by grinding, pressing, forming, or sintering.
Electrolysis has higher production efficiency and lower energy consumption but requires a large number of electrolytes and electrodes, so the cost is higher. In addition, the electrolysis process may also produce waste, which has a certain impact on the environment.
