Abstract：Taking low-grade quartz sand in Yangtze river seacoast as the main raw material,kaolin as binder,through dosing, mixing,molding,drying and sintering process,high-performance quartz porous materials was prepared. Through the study of the control mechanism of the process conditions on the properties of the sintered body,the performance of the quartz porous material is improved. The results show that when the control requirement of optimal quartz porous ceramics was as follows:the content of kaolin is 31%,the ratio of water to material is 1.4,the sintering temperature is 1150℃ and the holding time is determined as 1 h, the intact quartz porous ceramics can be prepared whose porosity was 49.88% and compressive strength was 5.01 MPa.
