Aluminum Carbide (Al4C3)-Powder
Product Description
Characteristic
Aluminum carbide, chemical formula Al4C3, is a carbide of aluminum. It has the appearance of pale yellow to brown crystals. It is stable up to 1400 °C. It decomposes in water with the production of methane.
Chemical formula：Al4C3
Molar mass：143.95853 g/mol
Appearance：colorless (when pure) hexagonal crystals
Odor：odorless
Density 2.93 g/cm3
Melting point：2,200 °C (3,990 °F; 2,470 K)
Boiling point：decomposes at 1400 °C

Application
Aluminum carbide particles finely dispersed in aluminum matrix lower the tendency of the material to creep, especially in combination with silicon carbide particles.
Aluminum carbide can be used as an abrasive in high-speed cutting tools. It has approximately the same hardness as topaz.
