Adhesive Is Used As A Biomedical Agent

The composition of hydroxyapatite Ca10(PO4)6(OH)2(HA) bioceramics is close to the inorganic components of human bone. It has good biocompatibility and can form a solid chemical bond with bone. It is an ideal hard tissue replacement material. However, the present prepared HA implants have high elastic modulus, low strength and poor activity. Phosphate glass adhesive was selected, and HA raw material powder was glued together at a temperature lower than the traditional sintering temperature through the effect of adhesive, which reduced the elastic modulus and ensured the material activity.
