    Abstract: The invention relates to producing continuous organic fibers by stretching from molten minerals. These fibers can be used for producing heat resistant threads, rovings, cut fibers, fabrics, composite materials and products based thereon. The inventive glass has the following chemical composition in mass percentage: 15.9-18.1 Al2O3, 0.75-1.2 TiO2, 7.51-9.53 Fe2O3+FeO, 6.41-8.95 CaO, 2.5-6.4 MgO, 1.6-2.72 K2O, 3.3-4.1 Na2O, 0.23-0.5 P2O5, 0.02-0.15 SO3, 0.12-0.21 MnO, 0.05-0.19 BaO, impurities up to 1.0, the rest being SiO2. The inventive method consists in loading a ground composition in a melting furnace, in melting said composition, in homogenizing a melt, in consequently stabilizing the melt in the melting furnace feeder, in drawing and oiling the fiber and in winding it on a spool. Prior to loading, the composition is held in an alkali solution for 15-20 minutes, and is then washed with flowing water for 20-30 minutes and dried.

  • Patent number: 7946131
    Abstract: The subject invention is directed to a method for producing a raw material or materials that can be used by themselves or in combination with other ingredients to make glass of high quality at high efficiencies and short production times. The raw materials are capable of high reactivity in a glass melting furnace and therefore will allow glass to be produced either at lower temperatures or shorter residence times at the same temperatures as compared with known methods.

  • Patent number: 7946130
    Abstract: In the process of producing a glass, a glass melt is formed from an initial glass batch, an inorganic or organic peroxide is include in the glass melt as a refining agent in an amount suitable for refining, and then the glass melt is refined at a refining temperature equal to or greater than a decomposition temperature of the inorganic or organic peroxide. The inorganic peroxides used in the glass-making process only include cations that are already present in components of the initial glass batch. The organic peroxides used in the glass-making process are chosen so that the organic residue remaining in the melt after release of oxygen is decomposed to volatile water and CO2.

  • Patent number: 7897534
    Abstract: Precursor materials and methods of making are disclosed. The precursor materials include at least one of a silica source, and a carbon source, with or without liquid and a binder The methods described include pyrolyzing the precursor material to form a carbonaceous mixture and heat treating the mixture for a pre-determined time and at an elevated temperature during which carbon and/or nitrogen react with silica in the mixture to form carbides and/or nitrides. The carbides and nitrides formed from said methods 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.
