  • Description Calcium arsenide has the molecular formula of Ca3As2 and the molecular weight of 270.0772 g/mol. It may be prepared by reacting the elements together. Since As sublimes at 614°C and Ca melts at 839°C, the latter is melted at about 875°C in an inert atmosphere like argon (not N2 which would form nitrides) and arsenic vapors are carried into the reaction zone by a stream of Ar gas: 3Ca + 2As + heat ? Ca3As2 Its CAS number is 12255-53-7. The standard Gibbs energies of formation of Ca3As2 was determined by a chemical equilibration technique yielding the following results: 3Ca + 2As ? Ca3As2 (solid) △G°= -723,800 + 172.8T (J/mol) (T = 1273 to 1573 K) Calcium arsenide has the zinc-blende (cubic) structure with a = 6.751 ? . It can also be prepared by the reduction of calcium arsenate by carbon: 2Ca3AsO4 + 5C + heat ? Ca3As2 + 2CaO + 3CO2
