Abstract: The present invention relates to ultrafine comminution of mineral and organic powders with the aid of ball-milling techniques employing, as the grinding medium, solid (nonporous) metal-carbide microspheres with diameters of from 10 to 100 .mu.m fabricated with the aid of high-temperature plasma-torch reactors from fully liquefied carbides of tungsten, thallium, niobium and vanadium.
Abstract: Complex (multicomponent) functional microgels with rapid formation kinetics and compositions thereof, as well as process for synthesizing said complex microgels in aqueous media.
Abstract: Aggregate-TiO.sub.2 pigment products comprising in each 100 parts, by weight, at least 50 parts, by weight, particulate TiO.sub.2 materials bound intrinsically with other pigmentary, subpigmentary and nonpigmentary components with the aid of inorganic and/or organic cements/adhesives.
Abstract: Composite pigment products containing from 4.5% up to 50%, by weight, of particulate titanium dioxide in which particles of the latter and other particulate pigmentary, subpigmentary and nonpigmentary components are cemented intrinsically with the aid of in-situ synthesized complex microgels.
Abstract: A fundamentally new papermaking process for the manufacture of paper, board and other wet-laid products on a paper machine under conditions ranging from acidic to alkaline from aqueous furnishes treated with in-situ-synthesized complex functional microgels.
