国内评价高温下碳化硅质陶瓷膜材料的标准和方法较少，本文基于碳化硅陶瓷膜材料具体实际应用工况条件，就材料的强度，耐高温、高压性能，孔结构及透气性能等方面，提出了系列测试标准和方法，并进行了测试。实验测得山东工陶院生产的碳化硅质陶瓷膜材料的抗弯曲强度能够达到18M Pa ，支撑体气孔率和孔径分别为34％和60μm ，分离膜平均孔径为17μm ，材料的线胀系数在5×10－6／k ，热震性能能够满足1000℃下10次不裂，在1m／min风速下材料的初始压降为750Pa。碳化硅陶瓷膜材料具有良好强度、高温热性能和较好的孔梯度结构。

T he criterions and methodes for evaluation of SiC ceramic membrane filtration material are little in domestic .To satisfy the working condition ,the material must have good mechanical strength ,resistance to high temperature and pressure ,good pore structure and permeability .From this ,the criterions and methodes are proposed and the SiC ceramic membrane samples were tested in this manuscipt .The bending strength ,porosity ,support and seperation membrane pore size of SiC ce‐ramic membrane material can reach 18 MPa ,34% ,60microns and 17 microns ,respectively .The ther‐mal expansion coefficient of material is 5 × 10-6/k and thermal shock performance could satisfy 10 times at 1000℃ .At the space velocity of 1m/min ,the pressure difference of the material is 750 Pa . The material must have good mechanical strength ,resistance to high temperature and pressure ,good asymmetric pore structure .
