Description
Strontium carbide has the molecular formula of SrC
2
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. SrC
2has 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.
Uses
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.
