Oxide -Non-Oxide Composites By Sol-Gel

Abstract

ABSTRACTIn this paper, three types of composites prepared using the sol-gel process are examined. Porous composites, based upon the dispersion of solid, oxide and non-oxide ceramic particles in a sol-gel derived matrix are described. A transparent composite, prepared by the impregnation of a polymer phase into a porous gel matrix is presented. Light-weight, “triphasic” composites, possessing good abrasion resistance and high fracture ductility, can also be fabricated by the polymer impregnation of a porous gel composite.
