Abstract

From our previous work, CaO-SiO₂-B₂O₃(CSB, CaO 45.8, SiO₂ 45.8, B₂O₃ 8.4mol%) glass-ceramic was proven to show fast dissolution rate in-vitro and in-vivo and Cerabone® A-W (Cera) hardly degraded in SBF. To control the biodegradation rate, we prepared glass-ceramics by mixing glass powders of Cera and CSB. The glass-ceramics sintered 800°C for 2h showed dense microstructure and were composed of crystalline β-wollastonite, apatite and a residual glass matrix. So mixing CSB with Cera enabled low temperature crystallization of β-wollastonite. In addition, as the amount of CSB glass powder increased, rate of dissolution and mechanical properties increased, but bioactivity slightly decreased.
