Abstract

A method for synthesizing low density, cellular inorganic materials from sol-gels has been developed. The method utilizes viscosity control during gelation to stabilize bubbles generated from freon droplets dispersed in the sol. Cellular silica, mullite and zirconia-toughened mullite have been fabricated with relative densities ranging from 10 to 45% and average cell sizes ranging from 30 to 1000 μm in diameter in dense matrices. This new class of low density, sol-gel-derived materials offers many opportunities in high temperature insulation, low permittivity substrates and catalyst supports, to name a few.
