Preparation method and application of particle size-controllable silica-zirconia composite sol
The invention belongs to the field of inorganic membrane material preparation, and especially relates to a preparation method and an application of a silica-zirconia composite sol. The preparation method comprises the following steps: introducing a zirconium alkoxide reagent to alkoxy silane, and discontinuously supplementing water to a system in the heating boiling soil preparation process to make the volume of the obtained solution unchanged in order to prepare the composite sol. The particle size of the composite sol is controllable, and the average particle size of the sol is about 100nm; and the sol is sintered under high temperature conditions through adopting a heat coating process to form a membrane, and introduction of the zirconium alkoxide reagent makes the membrane have good hydrothermal stability.
