基于冰模板导向的A1203多孔陶瓷制备
Al203 Porous Ceramics Prepared by Preezing-Casting Process Using Ice as Templates
摘要
Abstract
Porous alumina ceramics were fabricated by freezing casting process using ice as porecreating template. The microstructures of the samples were observed by SEM, the porosity and the compressive strength were also investigated. The results indicate that the porosity can be changed from 24％ to 85％ by controlling the process parameters, and SEM image presents cellular structure. The porosity is decreasing and the compressive strength is increasing with increasing the slurry concentration. The compressive strength is increasing with increasing the sintering temperature gradually. When the porosity is 85 ％, the compressive strength is 21 MPa.关键词
