| 摘 要： | 重点研究了在低粘度,高固相体积分数氧化铝浓悬浮体制备过程中,料浆的pH值对料浆性能的影响。结果表明:当pH值达到5左右时,Al_2O_3颗粒在水中的Zeta电位等于0,此时,料浆的粘度最大,分散效果最差。当pH值达到9时,Zeta电位的绝对值达到最大,此时料浆的悬浮稳定性最佳。

| Abstract: | The effects of pH on the performance of ceramic slurry during preparing aqueous alumina concentrated suspension with low viscosity and high solids volume loading are studied. The results shows : the Zeta potential is zero when pH of slurry is abound 5, which the viscosity of slurry is densest and dispersed effect is worst. However, The Zeta potential is biggest when pH of slurry is about 9, which stability of alumina in suspension is best. |
