摘要

中文摘要: 为了提高钙磷陶瓷材料性能，以含碳酸化羟基磷灰石纳米粉体（CHA）为原料，采用含水蒸汽CO2微波等离子体快速烧结新技术阻止CHA分解和实现多孔CHA /β-TCP双相生物陶瓷的纳米化。在优化工艺条件下，制得了平均晶粒尺寸为92nm，气孔率为55.9％，CO2含量为4％左右，压缩强度为13.7 MPa的多孔纳米TCP/CHA双相生物陶瓷。与常规马弗炉烧结相比，微波等离子体烧结时间缩短，烧结温度降低，能有效阻止CHA分解，提高了烧结效率。微波等离子体烧结是一种快速制备纳米生物陶瓷的有效方法。

Abstract

Abstract:Porous nanosized CHA/β-TCP biphasic bioceramics were prepared by microwave plasma sintering in a wet carbon dioxide atmosphere to improve its biological and mechanical performance. Through the optimization of sintering parameters including the sintering temperature and the holding time

porous bioceramics with average crystal size of 92nm

porosity of 55.9%

CO32- content of 4wt% and compressive strength of 13.7MPa were obtained. The comparison between conventional sintered specimens and microwave plasma sintered specimens showed that the latter exhibit smaller crystal size and higher carbonate content and compressive strength. Microwave plasma sintering is a promising method of preparing nanosized bioceramics.
