Inkjet ink systems comprising a gelling agent

Abstract: Inkjet ink systems are disclosed which comprise a) a liquid vehicle, b) a colorant, and c) a gelling agent. The gelling agent may be incorporated either into the liquid vehicle, into a second jettable composition, or onto a substrate. The gelling agent may also be attached to the colorant. In addition, several methods of generating an image are also described which utilize compositions comprising a gelling agent.

Process for the production of finely-divided metal and metalloid oxides

Abstract: There is disclosed an improved process and apparatus for the production of finely-divided metal and metalloid oxides by flame hydrolysis of corresponding metal and metalloid halides whereby fouling of burner apparatus is substantially completely avoided.

Method of producing extremely finely-divided oxides

Abstract: Finely divided metalliferous powders composed predominantly of metal oxides, metal carbides, free metals or mixtures thereof are produced by distributing heat convertible compounds of the corresponding metals together with a lesser amount by weight of carbon black throughout a volatile liquid medium, spraying the resultant dispersion through a heated zone to evaporate the volatile liquid and produce dried, fine particles of the metal compound in association with carbon black, and thermally treating the particles to obtain the required product. Possible starting materials are heat convertible compounds of Cu, Zn, Pb, Sn, Fe, Co, Ni, W, Mo, Al, Zr, Ti, Cr, B, Si, Ta, Ba, Mn, Th, Hf, U and Nb with sulphates, chlorides, bromides, iodides, fluorides, nitrates, perchlorates, sulphides, acetates, citrates, oxalates, formates, benzoates, carbonates, and tartrates preferred. The product may contain residual carbon which can be removed by oxidation or steam treatment. Alternatively, for certain purposes the product may contain up to 90% residual carbon. Carbon-free metals may be produced by using slightly less than the stoichiometric amount of carbon black and treating the product in a reducing atmosphere to reduce any minor amounts of oxides still present. The production of nickel oxide, nickel ferrite, nickel dispersion-strengthened with alumina, iron titanium dioxide, nickel-nickel oxide, ferro-molybdenum, ferro-tungsten, aluminium carbide and tungsten carbide is specifically described.ALSO:Finely divided metal oxides or metal carbides are produced by distributing heat-convertible compounds of the corresponding metals together with a lesser amount by weight of carbon black throughout a volatile liquid medium, spraying the resultant dispersion through a heated zone to evaporate the volatile liquid and produce dried, fine particles of the metal compound in association with carbon black, and thermally treating the particles to obtain the required product.
