在纯羟基磷灰石存在下，粘土和氧化铝在1150 ℃至1350 ℃下反应烧结，获得含莫来石的多孔羟基磷灰石陶瓷。XRD结果表明，加入莫来石后，羟基磷灰石分解为TCP。在含有10重量%的样品中检测到羟基磷灰石、β-TCP和莫来石。莫来石较多，在1150 ℃和1250 ℃下烧结2 h。气孔率随莫来石的加入而增加，随烧结温度的升高而降低。最高的孔隙率含量是在含有30重量%莫来石在所有烧结温度。(C)2011 Elsevier Ltd和Techna Group S.r.l. All rights reserved.
Porous hydroxyapatite ceramics containing mullite have been obtained from reaction sintering at 1150 degrees to 1350 degrees C of clay and alumina in the presence of pure hydroxyapatite. XRD results showed that hydroxyapatite decomposes to TCP by adding mullite. Hydroxyapatite, beta-TCP and mullite were detected in samples containing 10 wt.% and more mullite, sintered at 1150 degrees and 1250 degrees C for 2 h. Porosity amount increased by adding mullite and decreased by increasing sintering temperature. The highest porosity content was in samples containing 30 wt.% mullite at all sintering temperatures.
