Degradation Behavior of Calcium Sulfate/beta-Tricalcium Phosphate Composites in Tris

摘要

CaSO_4/beta-TCP composite powders were prepared by mixing CaSO_4 and beta-TCP. The CaSO_4 /beta-TCP (V_s: V_P) values were varied from 3:2 to 0:1. The composites were sintered at different temperatures. Tris was used to evaluate degradation behavior of the composites. The morphologies of composites before and after degradation were studied by SEM. The results show that degradation was increased with the increasing of V_s: V_p and decreased with the increasing of sintered temperatures.
