Hydroxyapatite and calcium strontium bismuth ferrite composite antibacterial biological material and preparation method thereof
The invention discloses a hydroxyapatite and calcium strontium bismuth ferrite composite antibacterial biological material and a preparation method thereof. Ferric nitrate, bismuth nitrate, calcium nitrate and strontium acetate are respectively used as solutes, and ethylene glycol and glacial acetic acid are used as solvents; calcium nitrate and phosphorus pentoxide are used as solutes, and ammonia water is used as a solvent. And mixing and stirring the two matched solutions according to different proportions to obtain a precipitate, and then filtering, cleaning, drying and calcining the precipitate to obtain the composite ceramic powder. The hydroxyapatite and calcium strontium bismuth ferrite composite novel antibacterial biological material prepared by a coprecipitation method has better biocompatibility and antibacterial property, and has potential application value in the field of bone tissue engineering.
本发明公开了羟基磷灰石和铁酸钙锶铋复合抑菌生物材料及制备方法。分别以硝酸铁、硝酸铋、硝酸钙、乙酸锶为溶质，乙二醇和冰乙酸为溶剂；以硝酸钙、五氧化二磷为溶质、氨水为溶剂。将上述两种配合好的溶液按照不同比例进行混合搅拌，得到沉淀物，然后将沉淀物进行过滤、清洗、干燥、煅烧，得到复合陶瓷粉体。用共沉淀的方法制备的羟基磷灰石和铁酸钙锶铋复合新型抑菌生物材料，该复合材料具有较好的生物相容性和抑菌特性，在骨组织工程领域具有潜在的应用价值。
