FIELD: industrial chemistry.
SUBSTANCE: invention refers to the field of industrial chemistry and in particular to production of new superconducting compounds in the sphere of high pressures from 17 hPa to 160 hPa. Synthesis of the mechanical mixture of calcium with phosphor oxide P2O5 or of calcium with calcium phosphate Ca3(PO4)2 is performed. The mixtures of calcium with phosphor oxide and of calcium with calcium phosphate are characterized by the molecular ratio 1:1. The synthesis is performed under the pressure of 65 hPa during 3-5 µs and at the temperature of 800 K in the storage ampoule with the protective shroud made of stainless steel.
EFFECT: production of the compound that contains calcium and has a higher superconducting transition temperature that the calcium under the removed pressure.
