METHOD OF PRODUCING POROUS CERAMIC FROM CALCIUM PHOSPHATES FOR TREATING BONE TISSUE DEFECTS

摘要

FIELD: ceramic industry.;SUBSTANCE: invention relates to ceramic materials for medicine, which can be used for filling bone defects in traumatology and orthopaedics, maxillofacial surgery and dental surgery. For producing porous ceramic, egg proteins with sucrose in ratio of 1:1 are whipped in foam, which are mixed with calcium phosphate powder in weight ratio of 1:1 to 1:5. Mixture is formed, it is dried at 180-200 °C, and it is sintered at a temperature of 850-1,200 °C.;EFFECT: method ensures production of ceramic material, characterised by porosity of 40-90 vol%, pore size of 0,01-20 MCM and compression strength of 8-15 Mpa.;1 cl, 1 dwg, 4 ex
