Abstract
This invention relates to a novel method of decreasing porosity of ceramics produced by sol-gel processing. The process of preparing chemically bonded sol-gel ceramics comprises phosphating a sol-gel derived oxide or hydrated oxide and polymerizing the phosphated product with heat treatment. Such combined sol-gel/chemical bonding process can be used to fabricate dense, thick ceramics or ceramic coatings for a variety of applications, including high temperature corrosion protection, wear resistance, dielectric properties, non-sticky surfaces, bio-active ceramics, thermal barrier ceramics, non-wetted surfaces, and others.
