black tetr; -8 mesh with 99% purity [CER91] [CRC10]

Strontium carbide has the molecular formula of SrC₂ and the molecular weight of 111.644 g/mol. It is obtained by heating strontium carbonate with carbon in the electric furnace. It resembles calcium carbide, decomposing rapidly in the presence of water or moisture, producing acetylene. SrC₂has the CAS number of 12071-29-3. It is a black, tetragonal crystal whose melting point is in excess of 1700°C. Its density is 3.19 g/cc. The a0c vector plane is shown for these polymorphs. SrC2 has been used in a metathetical reaction to produce transition elements carbides. These carbides are difficult to produce by any other means.

Strontium carbide is available in numerous forms and custom shapes including ingot, rod, plate and sputtering target. Highpurity forms also include carbide powder, submicron powder and nanoscale, single crystal or polycrystalline forms. Strontium carbide is generally immediately available in most manufactured volumes.
