| 摘 要： | 用金属醇盐水解法制备了稳定的勃姆石胶体，并用透射电子显微镜、激光散射等方法研究了胶体性质．实验表明，勃姆石胶体的酸度、浓度决定胶体质点大小、形状，从而决定胶体粘度．所以控制胶体的酸度、浓度便可以控制胶体粘度以及胶体质点的存在形态．

| Abstract: | Boehmite sol prepared by hydrolhation of aluminium tri-sec-butanol is investigated bymeans of transmiSSion electron microscopy(TEM) and toier scattering. It is found that the sol properties such as viscosity, and the size and structure of sol particles depend on the acidity and concentrationof the sol. Sol viscosity and particle structure can be controled by varying sol concentration and acidity. |
