Method for producing chitosan/hydroxyapatite/silica composite material

摘要

method of manufacturing composite material chitosan / hydroxyapatite / silica, intended for bone substitutes, the aqueous solution of salt chitozanowej, acetate, chloride, lactate and citrate chitosan is mixed with nanoproszkiem hydroksyapatytowym and possibly glicerofos foranem calcium by ultrasound to obtain homogeneous paste.subsequently moving to zolu acid metakrzemowego, all mixed, after which the obtained composite is dried konwekcyjnie at 50 - 100 degrees.method of manufacturing a composite material chitosan / hydroxyapatite / silica, intended for bone substitutes, characterised by the fact that the salt chitozanowu0105 like acetate, chloride, lactate and citrate chitosan is mixed with an aqueous solution of calcium acetate and an aqueous solution wodorofosf oran sodium, after which the obtained mixture is zol acid metakrzemowego,aqueous solution containing sodium phosphate and triphosphate pentasodowego, then all mixed, after which the obtained composite material is dried at a temperature of 50 konwekcyjnie - 100u00b0c.
