Abstract： |
A process for preparing the anti-sintering nanocrystals of metal oxide (Al2O3, TiO2, MgO, etc) features that the washing, drying and calcining steps used for preparing the hydrosol or alcohol gel of metal hydroxide by sol-gel method are controlled for controlling the granular diameter, crystal-phase structure, surface area and anti-sintering nature of metal oxide. |
