考察了物料配比和煅烧工艺对以凹凸棒石粘土、锯末（造孔剂）和水玻璃（粘结剂）为原料,在氮气保护气氛下煅烧制备凹凸棒石基碳复合陶粒性能的影响,利用复合陶粒的抗压强度、显气孔率优化材料配比和煅烧工艺,并通过XRD、SEM表征复合陶粒特性。结果表明凹凸棒石粘土、锯末、水玻璃的最佳质量配比为68∶20∶12,在最佳煅烧条件下（700℃）,可以制备出满足国家标准的水处理用陶粒,浸泡实验表明凹凸棒石基碳复合陶粒具有优异的耐水性能;该材料有利于微生物的附着。

A study was conducted to investigate the possibility of using palygorskite,sawdust and sodium silicate as starting materials to prepare ceramics by high temperature calcination at N2 atmosphere.Results revealed that： palygorskite and sawdust could be used to produce PCCC under the optimal material ratio and calcinated parameters.However,mechanical properties of prepared PCCC have proved to reach and even exceed the requirements in national standard.The experiments also exhibited that PCCC was a type of superior waterproof materials.Another test in a biological aerated filter reactor showed that microbe can be introduced into internal porous space in ceramics,the ceramics were most suitable to serve as biomedium for municipal wastewater treatment.
