FIELD: chemistry; medicine.
SUBSTANCE: invention can be used in production of materials for restoration of defects of bone tissue, dental seals. Method of producing colored single-phase calcium pyrophosphate involves mixing calcium lactate with disubstituted ammonium phosphate in molar ratio of 1. Mixing of initial components is carried out in planetary mill for 20–40 minutes with rotation speed of 300–500 rpm. Then water is added and grinding is carried out for 20–40 minutes. Obtained product is annealed at 600 °C.
EFFECT: invention enables to obtain calcium pyrophosphate powders of various shades of gray for use in 3D printing.
