Aluminum boride is a material with significant application value. Its unique physical and chemical properties make it widely used in many fields. This article will introduce the basic properties, preparation methods, application fields and future development trends of aluminum boride, aiming to deepen people’s knowledge and understanding of aluminum boride.
1. Properties of aluminum boride
Aluminum boride is a compound composed of aluminum and boron elements, and its chemical formula is AlB2. It is an intermetallic compound with a high melting point and hardness, as well as good electrical conductivity and corrosion resistance. The crystal structure of aluminum boride is a close-packed structure in which aluminum atoms occupy tetrahedral gaps and boron atoms occupy octahedral gaps. This structure gives aluminum boride good thermal and chemical stability.
2. Preparation method of aluminum boride
At present, the methods for preparing aluminum boride mainly include molten salt method, mechanical alloying method and chemical vapor deposition method. Among them, the molten salt method is one of the most commonly used methods. This method is to mix aluminum and boron oxides or elemental powders, then heat them to a high temperature to melt and react to form aluminum boride. The mechanical alloying method is to mix aluminum and boron powders and then use high-energy ball milling or grinding to mix and react to form aluminum boride fully. The chemical vapor deposition method chemically reacts with gaseous compounds containing boron and aluminum at high temperatures to produce an aluminum boride film.
