Abstract: A fibrous substrate having a first coefficient of thermal expansion and having porous characteristics is formed from discrete elements, such as carbon fibers, having anisotropic properties. A matrix formed from a refractory material encases the discrete elements and has a second coefficient of thermal expansion different from the first coefficient. The matrix has minimal chemical or mechanical bonding to the discrete elements to provide for a displacement of the matrix relative to the substrate with mechanical shock or changes in temperature. The matrix includes a first element having refractory properties and selected from the group consisting of hafnium, zirconium, tantalum, tungsten and molybdenum also includes a second element bound to the first element. The matrix is preferably formed by providing a mixture of a first gas containing the refractory element and a second gas containing the second element and by introducing the gases into a chamber containing the substrate. The gases are introduced into the chamber at an elevated temperature and with a pressure pulsating at a particular rate between first and second pressure limits to obtain the deposition of the refractory material on the discrete elements. The gases are periodically exhausted from the chamber and fresh gases are introduced into the chamber. The matrix may consist of first and second layers respectively having hafnium (e.g. hafnium carbide) and zirconium (e.g. zirconium carbide) as the refractory materials. These layers define pores with the substrate and further define an external surface. A layer of rhenium may cover the matrix in the pores and in the external surface.

Abstract: A method for producing high purity silica and ammonium fluoride from silicon tetrafluoride-containing gas wherein silicon tetrafluoride-containing gas from the acidulation of phosphorus-containing rock is recovered and the liquid entrainment is separated from the gas. The recovered gas is converted to an ammonium fluosilicate solution and is ammoniated to produce high purity silica and ammonium fluoride. The recovered gas can be converted to an ammonium fluosilicate solution either by absorbing the gas directly in a solution of ammonium fluoride or by first absorbing the gas in water to produce fluosilicic acid and then reacting the fluosilicic acid with ammonia or ammonium fluoride. In a second aspect, the invention provides a method of separately recovering high purity silica and ammonium fluoride from an impure aqueous fluosilicic acid solution by reacting the fluosilicic acid solution with ammonia or ammonium fluoride for a time and at a temperature sufficient to form ammonium fluosilicate solution, recovering solid ammonium fluosilicate from the solution, purifying the solid ammonium fluosilicate by dissolving the solid in high purity water or ammonium fluosilicate solution, recrystallizing solid ammonium fluosilicate, and recovering purified ammonium fluosilicate crystals from the solution, forming an aqueous solution of the purified ammonium fluosilicate crystals and ammoniating the solution for a time and at a temperature sufficient to precipitate silica, and separately recovering high purity silica and ammonium fluoride.

Abstract: This invention relates to abrasive products having a resinous binder which holds and supports abrasive grains on a backing sheet or in a fibrous sheet. Generally, thermally curable binders provide coated abrasives having excellent properties, e.g., heat resistance. In order to obtain the proper coating viscosities, solvent is commonly added to these binders. When polyester backings are used, curing temperature is limited to about 130 DEG C, resulting in long cure times. The long cure time along with solvent removal necessitate the use of festoon curing areas. Disadvantages of festoon curing areas include the formation of defects at the suspension rods, inconsistent cure due to temperature variations in the ovens, sagging of the binder, wrinkling of flexible webs, and shifting of abrasive grains. Although radiation curable resins solve the problems associated with thermally curable resins, with respect to festoon ovens, radiation curable resins are generally more expensive than thermally curable resins. This invention provides an abrasive product comprising abrasive grains bonded together or bonded to at least one major surface of a backing sheet, by a binder formed from a precursor comprising an aminoplast resin having on average at least 1.1 pendant  alpha , beta -unsaturated carbonyl groups per molecule. The binder is formed by curing the precursor at the  alpha , beta -unsaturated site of the carbonyl group, by radiation energy or by heat, in the presence of an appropriate initiator system. The aminoplast resin can also contain pendant amino or hydroxy functional groups, which allow polymerization with condensation curable resins, such as phenolic, melamine, urea, urethane, and furfural resins. Polymerization at the unsaturated site of  alpha , beta -unsaturated carbonyl group can be effected either by radiation energy or by heat, and curing at the sites of the amino or hydroxy functional group can be subsequently effected by heat.
