摘要： In-situ formation of glass-ceramic composites by the Self-propagating High temperature Synthesis (SHS) technique. The reagents used are: TiO.sub.2, B.sub.2 O, Al, Ti, B and MO where MO represents BaO, MgO, CaO and other similar oxides. BaCO.sub.3 may be substituted for BaO. The composition of the reaction products can be adjusted by adjusting the ratios of the reagents. All reagents are in powder form and the reaction can be carried out either in inert atmosphere inside a reaction chamber or in air without a chamber. The materials produced have crystalline TiB.sub.2 particles in a glassy matrix (aluminoborate glass). The TiB.sub.2 particles have a size of about 0.5 .mu.m. Advantages include processing simplicity and cost savings. The glass-ceramic composites produced are electrically conductive and find application where high strength, hardness and electrical conductivity are required.

摘要： Quartz is purified by removing mineral impurities, particularly alkali metal impurities, from within the quartz crystal lattice structure. According to the disclosed process, quartz crystals are subjected to a pretreatment that removes surface bound impurities and then contacted with gaseous HCl at a temperature of from 800.degree. C. to 1600.degree. C. for a period of time of from a few minutes to several hours, thereby diffusing the mineral impurities to the quartz crystal surface where they form salts with chloride ion, removing the salts, and recovering the purified quartz crystals.

摘要： Silica is reacted with sodium carbonate to form sodium silicate as a preliminary step in a glass melting process. Preferably, calcium carbonate-containing batch materials are calcined separately and then combined with the sodium silicate as liquefying is initiated. The materials may be substantially free of bubble-producing carbonates as the molten phase begins to form.

摘要： The disclosed process separates impurities, including admixed minerals other than quartz and quartz particles having relatively high levels of lattice impurities, from a quartz containing particulate material to recover a high purity quartz product. The process involves treatment with a solvent to reduce the size of the impurities relative to the quartz product and the thus treated material is then classified by size to recover the purified product. If impurities less soluble than the quartz product are also present, a second solvent treatment is conducted to reduce the size of the quartz particles relative to the less soluble impurity and a second classification by size is conducted. In a preferred embodiment, the quartz is subjected to a heat/quench cycle to fracture quartz particles thereby exposing occluded and interstitial impurities to the solvent leach. The intermediate product exiting the final solvent treatment and classification steps is dried, blended and roasted in a vacuum to remove gases.

摘要： An improved process to benefit colemanite and/or howlite minerals comprising the stages of: treating mineral with sulfuric acid in order to dissolve boron compounds; separating the solution formed from the solids in suspension; reacting said solution with hydrogen sulfide in order to precipitate the arsenic and iron impurities contained in the solution, and separating the impurities precipitated from the remaining solution as a beneficiated colemanite with boron. Said solution of the beneficiated colemanite with boron can be dried by spray fluidizing in order to obtain solid beneficiated colemanite with boron or said solution can be reacted with calcium hydroxide to precipitate a beneficiated colemanite with calcium borate which is separated from the remaining solution. This can be recycled for treatment with sulfuric acid to concentrate the mineral.The beneficiated colemanite with precipitated calcium borate, can be reacted with sulfuric acid in order to separate gypsum from the solution, while evaporating the remaining solution to precipitate boric acid. Said evaporation could be partial, while recycling the remaining solution to the evaporation stage to concentrate the boric acid.
