The process comprises providing a first material which comprises at least one non-oxide ceramic powder, and, at least one metal oxide, and providing a second material which comprises a caustic slurry composed of alkaline water and a solvent, and, combining the materials with stirring. There is also provided a composition of matter provided by the above-mentioned process which is a chemically bonded ceramic polymer comprising metal oxide and non-oxide ceramic bonds.
Abstract:
The present invention relates to castable refractory compositions based on magnesia aggregates. The compositions according to the invention consist of a plurality of dry components and a plurality of wet components, said castable refractory composition comprising, based on the total weight of the castable refractory composition, between 50 wt. % and 99 wt. % of a magnesia aggregate material; between 0.1 wt. % and 10 wt. % carbonaceous material; between 0.1 wt. % and 5 wt. % antioxidant; and a non¬ aqueous binder. The compositions according to the invention comprise no more than 2 wt.-% water; the fixed carbon in the composition is no more than about 10 wt.-%, and the antioxidant is selected from one or more carbide materials, nitride materials, boride materials, metals or metal alloys, or from combinations thereof. Also part of the present invention is the use of the compositions in casting, vibration casting, spray-casting, gunning, self-flowing, ramming, shotcrete or patching processes, and their method of formation.
