| 摘 要： | 采用添加造孔剂高温烧结法制备了氧化镁-二氧化钛（MgO-TiO2）复合无机陶瓷微滤膜支撑体。分别研究了相同烧结制度下不同最高烧结温度、相同最高烧结温度不同的烧结制度下样品的孔隙率、抗弯强度及纯水通量的变化情况。采用热重分析（TG-DSC）、电子扫描电镜（SEM）和万能试验机等对样品进行热分析、观察样品形貌及抗弯强度等性能测试。研究表明，最高烧结温度和烧结制度对样品的性能有很大影响，采用最高烧结温度为1 400 ℃、升温速率分别为4、8、2 ℃/min的1400-482烧结制度所制备的支撑体的性能最佳，孔隙率为37.57%，抗弯强度为108.65 MPa，纯水通量为4 040 L/（m2?h?MPa）。

| Abstract: | MgO-TiO2 composite inorganic ceramic microfilter membrane supports were prepared by adding porous former sintering at high temperature.The changes of porosity，bending strength and pure water flux of the samples under the same sintering system with different maximum sintering temperature and different sintering systems with the same maximum sintering temperature were investigated.Thermal analysis，microstructure and flexural strength of samples were carried out by means of TG-DSC，SEM and strength universal testing machine respectively.Research showed that the maximum sintering temperature and sintering temperature system had great influence on the performance of the samples.The excellent performance of supports with porosity of 37.57%，flexural strength of 108.65 MPa and pure water flux of 4 040 L/（m2?h?MPa） could be fabricated under the maximum sintering temperature of 1 400 ℃ and the sintering temperature system of 1400-482 with the heating rate of 4，8，2 ℃/min. |
