Zinc Compound Containing (zn) Patents (Class 106/419)
  • Patent number: 11884548
    Abstract: A method of preparing a transparent zinc carbonate is disclosed. The method includes dissolving a zinc source in aqueous ammonium carbonate, removing metal impurities from the solution, injecting CO2 into the zinc ammonia carbonate solution, heating a resulting slurry to a temperature of about 100° C. or more until the ammonia is substantially absent from the solution, and drying the resulting zinc carbonate at a temperature from around 150° C. to 300° C. for a length of time that removes water, but retains a significant part of the CO2 content. The ammonia and the carbon dioxide are present in the aqueous solution in a ratio by moles or by weight effective to dissolve the zinc. A nano zinc oxide can be prepared by drying the zinc carbonate at a temperature of 300-400° C. for a length of time sufficient to remove substantially all of the CO2.

  • Patent number: 8075684
    Abstract: An aqueous liquid solution containing soluble salts of coloring metals—particularly manganese and ferric nitrate along with a sugar source and fulvic and/or humic acid can be readily applied to rock, soil or artificial construction surfaces impart a natural color tone to such surfaces. In this manner the visibility manmade disturbances is quickly and easily reduced and disturbed areas readily blend into the natural background. The liquid solution can be readily sprayed on rock or other surfaces. When the ambient temperature is warm natural color will develop in 4-8 days.

  • Patent number: 8016935
    Abstract: An anticorrosion ferrite-based pigment, derived from a hydrometallurgical purification process of EAF dust. EAF dust is generated in an electric arc furnace for carbon steel production by processing scrap metal, direct reduced iron and/or pre-reduced hematite, and using CaO-rich slag; from a condensation reaction of metals vapors of Fe, or Zn and of Mn, Mg, Si and/or Al, and suspended CaO particles and oxygen. The pigment contains a non-toxic amount of lead, and includes condensed metal oxides, comprising ferrites MOFe2?3, M being Zn, Fe, Mn and Mg, and combinations thereof. The condensed oxides have ferrite structures preserved from the EAF dust, and form aggregates thereof. The pigment includes CaO entrapped by the ferrite structures and being partially available to react with humid air and/or water to protect the substrate against corrosion. The pigments are coated or uncoated. They are used for antifouling or paint formulations.

  • Patent number: 7789958
    Abstract: Corrosion-inhibiting pigments based on manganese are described that contain a trivalent or tetravalent manganese/valence stabilizer complex. An inorganic or organic material is used to stabilize the trivalent or tetravalent manganese ion to form a compound that is sparingly soluble, exhibits low solubility, or is insoluble in water, depending upon the intended usage. Specific stabilizers are chosen to control the release rate of trivalent or tetravalent manganese during exposure to water and to tailor the compatibility of the powder when used as a pigment in a chosen binder system. Stabilizers may also modify the processing and handling characteristics of the formed powders. Manganese/valence stabilizer combinations are chosen based on the well-founded principles of manganese coordination chemistry. Many manganese-valence stabilizer combinations are presented that can equal the performance of conventional hexavalent chromium or tetravalent lead systems.

  • Patent number: 7754106
    Abstract: A release agent is flash evaporated and deposited onto a support substrate under conventional vapor-deposition conditions and a conductive metal oxide, such as ITO, is subsequently sputtered or deposited by reactive electron beam onto the resulting release layer in the same process chamber to form a very thin film of conductive material. The resulting multilayer product is separated from the support substrate, crushed to brake up the metal-oxide film into flakes, and heated or mixed in a solvent to separate the soluble release layer from the metallic flakes. Thus, by judiciously controlling the deposition of the ITO on the release layer, transparent flakes may be obtained with the desired optical and physical characteristics.
