以石膏模具废料为原料，在50-190 ℃的水热条件下，用磷酸氢二铵溶液合成了多孔羟基磷灰石（HAp）块体，并对其性能进行了研究。在50 ℃和100 ℃条件下，用0.5 mol dm（-3）（NH 4）（2）HPO 4处理石膏废弃物样品15天和2天，可完全转化为HAp。本文研究了水热反应条件如反应温度、反应时间和（NH_4）（2）HPO_4浓度对新型HAp整体材料的形成及其多孔性能的影响。
Porous hydroxyapatite (HAp) monoliths were synthesized from gypsum mold waste with diammonium hydrogen phosphate solution by hydrothermal treatment at 50-190 degrees C and their properties studied. Gypsum waste samples could be completely converted to HAp with 0.5 mol dm(-3) (NH4)(2)HPO4 at 50 degrees C in 15 days and 100 degrees C in 2 days. This paper describes the effect of hydrothermal reaction conditions such as reaction temperature, time and concentration of(NH4)(2)HPO4 on the formation of new HAp monoliths and their porous properties.
