Aluminum Diboride AlB2 Powder Properties

What is Aluminum Diboride AlB2 Powder ?

Aluminum boride's chemical formula is AlB2, also called aluminum diboride. It is a binary compound formed by aluminum elements and boron elements. Aluminum boride is a red solid under normal temperature and pressure. It loses its surface gloss when heated. It is stable in cold dilute acid and decomposed in hot hydrochloric acid and nitric acid.

Aluminum boride AlB2 is one of two compounds of aluminum and boron; the other is AlB12, commonly called aluminum boride. AlB12 is a black and shiny monoclinic crystal with a specific gravity of 2.55 (18°C). It does not dissolve water. The single crystal of AlB2 is parallel to the hexagon of the base.

The aluminum boride structure is similar to that of graphite flakes. There are Al atoms between B atoms and B atoms, which is very similar to the structure of magnesium diboride. The AlB2 single crystal exhibits metal conductivity along an axis parallel to the hexagonal plane of the substrate.

Aluminum diboride is hazardous because it reacts with acid and hydrogen to generate toxic gases. For example, it reacts with hydrochloric acid to release borane and aluminum chloride.

The crystal structure of AlB2 is often used to describe the prototype structure of intermetallic compounds. There are many structure types in the AlB2 structure family.

Product performance of Aluminum Diboride AlB2 Powder:

Aluminum boride is an ionic compound with a hexagonal crystal structure. Aluminum boride will be transformed into a superconductor at an absolute temperature of slightly 40K (equivalent to -233 ℃). And its actual operating temperature is 20 ~ 30K. We can use liquid neon, liquid, or closed-cycle refrigerators to finish cooling to reach this temperature. Compared to the current industry using liquid helium to cool the niobium alloy (4K), these methods are more simple and economical. Once it is doped with carbon or other impurities, magnesium diboride in a magnetic field, or a current passing, the ability to maintain the superconducting is as much as niobium alloys, or even better.

How is Aluminum Diboride AlB2 Powder produced?

Thermochemical method: 

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 method: 

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.
