Abstract: A porous refractory in the K2O—SiO2—B2O3 system is formed by chemical direct foaming by heating to over 600° C., resulting in adherent black or white foam. The foam can function as highly porous thermal insulation, a high or low thermal emissivity surface, as a sealant for deteriorated refractory surfaces, as a filler for pockmarks/holes/gaps or as a bonding agent for parts with large gaps between them.

Abstract: A carbon material is formed by heat-treating a carbonaceous material in a reaction mix of boron oxide or its precursors and ammonia-generating phases such as melamine or its like in a nitrogen atmosphere to temperatures of 1600 to 2000° C. The surface of the carbonaceous material is transformed into a carbon material that is resistant to oxidation to temperatures of 900° C., enabling machined components to be utilized for weeks at that temperature. The carbon material also is stable in inert or vacuum environments to temperatures in the range of 1500 to 2000° C., enabling its use as aluminum evaporative boats and the like.
