The invention is directed to a method for producing low sintering fine-particle multicomponent glass powder having a particle size of the primary particle in the nanometer range. The method utilizes microemulsion techniques with subsequent separation of the particles out of the emulsion and calcination for utilization as glass flow having a sintering temperature &lt;900.degree. C. or in a glass flow, for generating thin transparent layers or for generating color decorations on glass, glass ceramic or ceramic substrates after adding a coloring pigment to the glass flow. The microemulsion for producing the nanoscale glass powder particles is generated from a nonionic ambiphilic emulsifier with a component of 10 to 15 percent by weight on the emulsion, from an oil phase having a portion of 50 to 70 percent by weight and a glass precursor-containing aqueous salt solution having a portion of up to 31.3 percent by weight with salt contents of up to 45 percent by weight.

Method of producing fine-particle multicomponent glass powders for use

Large area decorations of glazings, ceramic paint or the like on glass ceramic, glass, ceramic or similar meltable substrates, in particular on glass ceramic cooking plates, are applied by the new method by means of a laser beam which is widened linearly over the entire width of the area to be decorated, as it were in a zone melting method. The linear energy supply zone is advanced at a speed high enough for essentially only the decorating material to be melted on or burnt in but ensuring that the thermal conduction front does not move appreciably into the substrate material.

Method for melting and/or burning-in of at least one layer

A process for centrifugal coating of large-surface, arched elements, especially of cathode-ray-tube displays or screens, in which during the centrifugal coating, a disk matched to approximately the shape of the surface to be coated is rotated at a distance of 1 to 10 mm above the surface to be coated at approximately the centrifugal speed equidirectional with the surface to be coated.

Coating process

In a process for manufacturing fiber reinforced composites made or inorganic sinterable material and inorganic fibers the fibers are continuously passed through a bath which works acccording to the fluidized bed principle and which contains a solution of at least one metal alkoxide of the elements of the first to the fourth main groups of the periodic table and the forth and fifth subgroups of the periodic table, which solution already comprises products of hydrolysis and their condensation products, and the fibers moistened with the solution are wound one upon the other to form layers, the moistened and wound fibers are dried, the metal alkoxides on the fibers are completely hydrolyzed and the products of hydrolysis are polycondensated, and the layers of the fibers being adhered by the powder and the polycondensation products of the products of hydrolysis of the metal alkoxides are hot pressed.

Fiber reinforced composites and process for manufacture

In a process for producing transparent, electrically conductive, augmented layers of indium oxide by means of a dipping process, during which the substrate to be coated is dipped into a solution containing hydrolyzable compounds of indium, whereupon the substrate is withdrawn from the solution, is dried, and tempered at temperatures of up to 500.degree. C., a dipping solution is used which, in addition to the indium compound, contains at least one additional hydrolyzable compound of an element in the 2nd, 4th or 5th main groups, in the 1st, 2nd, 4th, 5th or 8th subgroup of the periodic system of elements, or of the rare earths.

Dipping process for the production of transparent, electrically

Optical blanks, for example spectacle lenses, are produced by hot-blank pressing or injection molding of polyorganoheterosiloxanes which are obtainable by hydrolytic polycondensation of at least one titanium-, zirconium-or tin-compound, at least one organofunctional silane and, where applicable, at least one inorganic oxide component. For control of the optical characteristics and working properties, polyorganoheterosiloxanes which have a polymerizable organic radical may be modified by additional polymerization with other copolymerizable condensates or monomers.

Process of making optical blanks

A process for the production of transparent, electrically conductive, infrared-reflecting indium oxide-tin oxide layers, especially on glass panes, involves steps wherein the glass panes are dipped into a first solution containing a hydrolyzable silicon compound and hydrolyzable compounds of titanium, zirconium, aluminum, tin or tantalum;
