摘要： Methyl silicone resins are pyrolized in a non-oxidizing atmosphere to form a translucent glass comprised of silicon, oxygen and carbon where silicon atoms are chemically bonded to carbon and oxygen atoms, but there are essentially no chemical bonds between carbon and oxygen atoms. The translucent silicon-oxy-carbide glasses of this invention resist devitrification and decomposition in oxidizing or reducing atmospheres at temperatures of about 1250.degree. C. or greater. Methods for forming silicon-oxy-carbide glass articles are disclosed, along with specific methods for forming silicon-oxy-carbide glass fibres, composites, and cellular structures.

摘要： A process for manufacturing open porous sintered bodies with large open pore volume and defined pore diameters and which at least predominantly consist of glass-ceramics. They are obtained by sintering a mixture of sinterable powder and an inorganic soluble salt with defined grade of grain, the melting point of which is above the densification temperature of the sinterable powder. For the formation of a molded body the mixture of sinterable powder and inorganic salt is submitted to a molding process. The molded body is sintered in a sintering process and the soluble salt being contained in the molded body is lixiviated. As a main constituent the sinterable powder contains a pulverized crystallizable glass powder. The sintering process is performed in such a way that the crystal phases being produced during the crystallization of the crystallizable glass, and therefore the material properties, too, are controlled by the guidance of the sintering process as well as by the ion exchange taking place between the sinterable powder and the inorganic salt and which is controlled by their composition. Afterwards, the sintered body is transformed to the final glass-ceramic texture.

摘要： New type porous cordierite ceramics having a new characteristic interconnecting open cellular structure and a hollow microspherical cordierite glass powder with a shell devoid of any pores or provided with a few or an abundance of open pores which is used as a starting material for the porous cordierite ceramics. The porous cordierite ceramics are produced by subjecting a starting solution containing an alkyl silicate, an aluminum salt and an magnesium salt optionally with other compounds in an organic or aqueous organic solvent to spray thermal decomposition to prepare the hollow microspherical cordierite glass powder, and then processing the cordierite glass powder to a shaped body after or before an optional heat treatment and firing the shaped body at a temperature below the melting point of cordierite. The porous cordierite ceramics are useful as a carrier for gas chromatography or various chemical reactions.

摘要： A method for the manufacture of foamed glass includes providing a mixture of a finely divided glass and a bonding agent. The bonding agent is selected from the group of aqueous solutions of the oxygen acids of beryllium, boron, aluminum, silicon, germanium, arsenic, antimony, tellurium, polonium, astatine and phosphorous, the aqueous solutions of the anhydrides of the oxygen acids, and the aqueous solutions of the salts formed by the oxygen acids and the basic oxides, and basic hydroxides of beryllium, boron, aluminum, silicon, germanium, arsenic, antimony, tellurium, polonium, astatine and of the transition metals having a variable oxidation number. The mixture is dried at a temperature from 20.degree. to 600.degree. C. to thereby transform the bonding agent into a gel having water bound thereto. The dried mixture is heated to a temperature from 800.degree. to 1,000.degree. C. to thereby melt the mixture and release the bound water from the gel. The released water forms a vaporous cellulating agent which effects the foaming of the molten glass.

摘要： To increase the thermal insulating properties of a vitreous material of closed cellular structure, the material while still in a molten state is subjected to pressure or stretching or a combination of the two forces in mutually perpendicular directions, whereby the cells become compressed or stretched or both, the height of the cells in the deformed material being reduced to a relatively considerable extent with respect to their original form. Deformation may be such that the cells resemble hollow fibres. The deformed material may be further treated, to roughen at least one surface, by placing the material while still plastic in contact with granular material, such as sand, of higher melting point so that the granular material becomes embedded on the surface. Tiles or bricks of the material can then be more easily cemented to other surfaces.
