Beschreibung

Aluminum 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.

Chemische Eigenschaften

powder(s); made by reaction of the elements above 600°C; high neutron absorption; used as a nuclear shielding material [HAW93] [CIC73]

Physikalische Eigenschaften

Aluminum diboride:
Crystal system, lattice parameters, structure type, Strukturbericht, Pearson, space group, structure type (Z): Hexagonal a = 300.50 pm; c = 325.30 pm C32, hP3, P6/mmm, AlB type (Z = 1).
Density (ρ/kg.m–3): 3190; Specific heat capacity (cP/J.kg–1.K–1): 897.87; Vickers or Knoop Hardness (HV or HK/GPa) (/HM): 9.61 HK; Other physicochemical: Temp. transition to AlB at 12 920°C. Soluble in dilute HCl. Nuclear shielding material (uses).

Verwenden

Aluminum 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.
