摘　　要：选用不同分散剂,研究了不同分散剂含量对硅藻土基多孔陶瓷的影响.试验结果表明,六偏磷酸钠对浆料的稀释作用最好,加入量为2%时,浆料粘度是7.1 mPa.s;pH值2.6为硅藻土基多孔陶瓷浆料(不含分散剂)的等电点,由于浆料粒子相互吸引而聚集,所以浆料pH值离等电点越远,分散剂对浆料的稀释效果越好.In this study, the influence of different dispersing agents on diatomite-based porous ceramic slurry viscosity was discussed. The experiment results showed that sodium hexametaphosphate had an excellent dilution effect on slurry, and the slurry viscosity was 7.1 mPa · s in addition of 2%. The pH value of 2.6 of diatomite ceramic slurry （dispersion-free agent） was the isoelectric point. As the slurry particles gathered for the mutual attraction, the farther away the slurry pH value is from the isoelectric point, the better the dilution effect of the slurry is.
