이붕소화 알루미늄

개요Aluminum diboride (AlB2) is an inorganic compound with a cyclic structure formed by aluminum and boron, and is a high calorific value boron based fuel with high potential for application. Aluminum diboride has a very similar structure to magnesium diboride. It has low specific gravity and high mechanical properties. The longitudinal tensile strength of unidirectionally reinforced boron-aluminum composites is about 1.2~1.7GPa with different processes and raw materials, and the modulus of elasticity is about 200~240GPa. The longitudinal specific modulus of elasticity and specific strength are about 3~5 times and 3~4 times of those of titanium alloy duralumin and alloy steel respectively.

용도Aluminum diboride is a solid material that has a high melting point and hardness. It is commonly used to make high-temperature ceramics and materials that are resistant to wear.
