Aluminum boride (AlB12, Aluminum dodecaboride) contains icosahedral B12 structures, which are connected by Al atoms. The standard heat of formation of AlB12 is -(201±42) kJ/mol. The decomposition temperature is 920 degrees Celsius. Aluminum borides include AlB2, AlB4 and AlB12. Above 920°C, AlB2 decomposes to form AlB12. AlB12 can also be prepared from B2O3 or other boron-containing minerals by the aluminothermic method. It decomposes into elemental substances at 1900°C.
The structure of Aluminum dodecaborides is similar to that of intermetallic compounds. Its structure mainly depends on the crystal structure of aluminum metal and boron rather than their valence relationship.
Melting point: decomposes to boron and carbon at 1900℃
Density: 2.550
Solubility: soluble in hot HNO; in soluble in acid solutions
Color: yellow-brown
Water solubility: soluble hot HNO3; insoluble acid, alkalies
It is obtained by mixing boron trioxide and aluminum sulfide and heating them for reaction.
Aluminum borides is an important high-temperature structural material with good thermal conductivity and mechanical properties. It is widely used in aerospace, metallurgy, electronics and other fields. Aluminum dodecaboride is a common form of Aluminum dodecaborides. It has a higher melting point and hardness, so it is widely studied and used.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
