Abstract: A recession resistant coated ceramic part. The ceramic part has a ceramic substrate and a recession resistant coating disposed on the substrate. The coating includes a plurality of layers diffusion bonded to each other and to the substrate respectively. The top most layer is characterized by a greater resistance to recession due to oxidation than that of the substrate.

Abstract: The present application is directed to ceramic compositions and, more specifically, to a silicon carbide composition and method of making it through liquid phase sintering. In one embodiment, the present invention is directed to an unsintered ceramic body including at least one liquid phase sintering aid. The unsintered ceramic body further includes a boron containing compound, a free carbon containing compound, and silicon carbide. In another embodiment, the present invention is directed to a method of making a sintered ceramic body. The method includes combining at least one liquid phase sintering aid, a boron containing compound, a free carbon containing compound, and silicon carbide to form a green ceramic, shaping the green ceramic into a ceramic body, and sintering the ceramic body.

Abstract: The present invention relates to a method for making a hexagonal boron nitri de slurry and the resulting slurry. The method involves mixing from about 0.5 wt.% to about 5wt.% surfactant with about 30 wt.% hexagonal boron nitride powder in a medium under conditions effective to produce a hexagonal boron nitride slurry. The present invention also relates to a method for making a spherical boron nitride powder and a method for making a hexagonal boron nitride paste using a hexagonal boron nitride slurry. Another aspect of the present invention relates to a hexagonal boron nitride paste including from about 60 wt.% to about 80 wt.% solid hexagonal boron nitride. Yet another aspect of the present invention relates to a spherical boron nitride powder, a polymer blend including a polymer and the spherical hexagonal boron nitride powder, and a system including such a polymer blend.
