Abstract
High-temperature-resistant transparent monolithic member or coating on a substrate consisting of aluminum and silicon in an atom ratio of about 2:1 and in reacted oxide form. The member or coating is formed by reacting precursor alkoxides of aluminum and silicon in the presence of water or reacting precursors derived from these alkoxides, gelling the reacted precursors, and drying the gel in the form of a monolithic member or coating. The dried member is then heated to evolve all residual hydrogen and carbon and residual water and to eliminate porosity to form the monolithic member or coating.
