摘　　要：以天然石英为骨料、粘土和长石为基料,采用喷涂工艺制备石英网眼多孔陶瓷。通过显微镜对其显微结构的观察,多孔陶瓷整体结构和孔径厚度非常均匀,具有连续开孔三维网状骨架结构,几乎没有很细的孔径存在。对不同气孔率多孔陶瓷的力学性能研究表明多孔陶瓷的抗压强度随孔隙率的减小而增大。A Spray method was applied to prepare porous silica ceramics. The natural silica, clay and feldspar was chosen as original materials. The porous silica ceramic was a very uniform macrostructure and few flaws by investigated its microstructure. The compressive strength increased when the ratio of pore reduced.
