Calcium phosphate brushite cements made from substituted tricalcium phosphate Ca3(PO4)2 and reinforced with silicate glass fiber
The reinforcement of reaction hardening phosphate materials (phosphate cements) for bone implants, based on isomorphically cation- (Na+, K+) and anion- (SiO44-, SO42-) substituted tricalcium phosphate (β and α-TCP, Ca3(PO4)2), that are reinforced with silicate (basalt-based) fiberglass, is considered. The obtained materials were characterized by the XRD and SEM methods, mechanical compression tests were carried out, the setting times of cements were determined, changes in the pH of the aqueous medium in contact with the cements under study were measured. Microstructure analysis has been shown that the surface of the reinforcing fiber in contact with the matrix of hardening cement is partially corroded with the formation of phosphate microparticles on it. By pH-metry it was found that the samples during prolonged contact with water do not significantly change the pH value of the aquatic environment, which remains in the nearly neutral range from 5 to 7.5, favorable for further biological tests.
