MANUFACTURE AND USE OF ENGINEERED CARBIDE AND NITRIDE COMPOSITES
摘要
<p>Carbides and nitrides are provided containing a controlled amount of pre-determined diluents and methods for their manufacture and use are disclosed The carbides and nitrides with pre-determined diluents are formed by optionally pyrolyzing a precursor material to foml a carboneous mixture and heat treating the carboneous mixture for a pre-determined time and at an elevated temperature during which carbon and/or nitrogen reacts with silica in the mixture to form carbides and/or nitrides and controlled amounts of pre-determined diluents The carbides and nitrides disclosed herein may be used as blowing agents in a glass, ceramic, or metal forming processes or for promoting dispersion of the carbides and nitrides throughout a glass, ceramic, or metal composite</p>
