| 摘 要： | 醇盐水解法广泛用于金属氧化物溶胶-凝胶的制备．一般，醇盐水解有二种方式，一是通过金属醇盐的完全水解、生成沉淀、继而胶溶形成溶胶；另一种是通过控制水解直接制得溶胶或凝胶．其中，由于醇盐控制水解法成胶容易，胶凝时间可以通过控制参数进行调节，所得胶粒细小均匀，因

| Abstract: | The preparation of yttria-stabilised zirconia (YSZ) sol and the mechanismsof sol formation and sol-gel transition have been studied. The YSZ sol was prepared viacontrolled hydration of propanol zirconia alkoxide doped with yttrium nitrite. The sol formation process and gelling time are affected by many parameters such as water content,acetic acid content and the amount of propanol. The stability of the sol can be greatlyimproved by adding appropriate polymer. |
