摘要：

The effects were studied of additives on the sintering and properties such as the compressive strength and chemical durability of ceramics of calcium pyrophosphate, tricalcium phosphate and hydroxyapatite. In improving the compressive strength of these calcium phosphates, the effect of additives was found to be in the order Na2O >> CaF2 > MgO >> Al2O3, SiO2 for the case of single-doping, and was most marked in the combination of Na2O-MgO-Al2O3 for the complex addition. It was also found that the chemical durability of the calcium phosphates was improved greatly by using a single or complex additives.
