Application of Silica Sol-Gel in Colloidal Forming of Ceramics
|
Abstract:
A novel colloidal forming processing of ceramics was investigated. The characteristic of silica sol-gel was applied successfully to colloidal forming of ceramics. The process is based on the casting of the slurry, containing powder and silica sol prepared by hydrolysis of tetraethoxysilane (TEOS) at pH 12.8. Then the mixture forms gelled parts through silica sol-gel. Ceramic green parts with strength of 5MPa can be obtained by this method. The forming process has advantages of low toxicity and high consolidation rate.
