Ceramic membranes with enhanced thermal stability |
摘要 |
A method of creating a ceramic membrane with enhanced thermal stability is disclosed. The method involves combining quantities of a first metal alkoxide with a second metal, the quantities selected to give a preselected metal ratio in the resultant membrane. A limited amount of water and acid is added to the combination and stirred until a colloidal suspension is formed. The colloid is dried to a gel, and the gel is fired at a temperature greater than approximately 400 DEG C. The porosity and surface area of ceramic membranes formed by this method are not adversely affected by this high temperature firing.
