摘要： A ceramic kiln-fired product which comprises glass, fly ash, and a clay binder. Further provided is a method for preparing raw material suitable for forming a shaped, kiln-fired, ceramic product. The method comprises mixing glass, fly ash, and a clay binder with from about 10 wt. % to about 15 wt. % water, on a dry weight basis, to form an aqueous mixture, separating the aqueous mixture using a mesh of from about 10 to about 12 screen into first and second portions, the first portion comprising the aqueous mixture which does not pass through the mesh and the second portion comprising the aqueous mixture which passes through the mesh, and drying the second portion until the moisture content of the second portion is less than about 0.5 wt. % to form the raw material. The present invention also provides a tile glazing formulation which may be used with the ceramic product of the present invention, as well as a method of using the formulation. The glazing formulation comprises, on a dry weight basis, about 70 wt. % to about 75 wt. % frit, about 8 wt. % to about 11 wt. % clay, about 2 wt. % to about 6 wt. % feldspar, about 1 wt. % to about 2 wt. % flint, about 6 wt. % to about 8 wt. % zinc oxide, about 6 wt. % to about 8 wt. % alumina.

摘要： A method for producing a highly loaded, aqueous suspension having a pourable viscosity and containing from 20 to 50 volume percent colloidal ceramic or metal particles. A biologically produced polymer dispersant having a high density of carboxyl functional groups and an average molecular weight of at least 1,000 is solubilized in water in a quantity of less than 1.0 percent dry weight basis of particles. The ceramic or metal particles are then introduced to the solution, and agitated to form a substantially nonagglomerated suspension. The polymer dispersant may be produced by a bacterium grown in situ with the particles. A biologically produced polymer gelling agent that is miscible with the polymer dispersant may be admixed into the suspension, which is then maintained in a nongelled state while being supplied to a mold. The suspension is then exposed to a gel-triggering condition to form a gelled, sinterable article.

摘要： A novel alkaline earth metal carbonate product for use as a raw material in the glass manufacturing process is disclosed. The alkaline earth metal carbonate becomes a part of the liquid phase in the glass furnace more readily and at a lower temperature; it decomposes to release carbon dioxide gas more rapidly so that all of the gas can escape from the molten glass more easily. Using these alkaline earth metal carbonate compositions, the production capacity of a glass furnace is increased.

摘要： A process for the elimination of iron from silica sand, comprising: abrasive-attritioning sand particles by subjecting the sand particles, in a single step and under dry conditions, to centrifugal rotation and simultaneously imparting an agitation with a translative eccentric movement and downstream and upstream movements causing that substantially all the sand particles be abrasive attritioned to each other wearing their surfaces to remove impurities covering said sand particles; and separating said iron impurities from said sand particles by magnetic separation, flotation or other known methods, thus simplifying the conventional processes just to one attrition step and suppressing the chemical treatment with acids or alkalis which was necessary in conventional processes.

摘要： An improved sol-gel process is disclosed for fabricating large monoliths of silica or ceramic material, which are substantially free of cracks. Following formation of the gel, but before the gel is dried, the gel is subjected to a hydrothermal aging treatment, in which it is heated in an autoclave to a temperature of between 100.degree. and 300.degree. C., for a time duration of at least about one hour. This hydrothermal aging treatment causes silica (or ceramic) particles to migrate and fill small pores in the porous gel matrix, such that the average pore size increases and capillary forces encountered in the subsequent drying step are reduced to a point where cracking of the gel is substantially eliminated.

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： The present invention relates to a process for the production of a glass from silica as a raw material by a vacuum melting method, in which a high quality glass is produced efficiently by compounding a silica powder containing an excess amount of the accelerator for phase conversion and silica powders containing substantially no such accelerator or by introducing silica powders in a solution containing an accelerator for phase conversion, adding an acid or basic component to the mixture to adjust the pH thereof, stirring the mixture for mixing, and subjecting the mixture to dehydration and drying to obtain silica powders containing the accelerator for phase conversion in proper quantities, filling the resultant silica powders in a vessel and heating the powder to form a sintered molded body having cristobalite phase having a self-supporting property and also having a proper matrix strength and a high porosity, and then heating the sintered body under vacuum.
