  • Urea-zinc oxide composition and process
    Patent number: 3981713
    Abstract: A particulate fertilizer comprising urea particles having a fertilizing quantity of available zinc in the form of zinc oxide which is homogeneously dispersed throughout the urea particles. The urea-zinc oxide particles may be prepared by dissolving zinc oxide into molten urea containing less than 12% by weight water, based on water/urea + water, and solidifying the molten urea-zinc oxide blend into particles of any desired form.
    Type: Grant
    Filed: July 23, 1971
    Date of Patent: September 21, 1976
    Assignee: Mississippi Chemical Corporation
    Inventors: Gerald L. Tucker, Elmer Ladelle Blanton
  • Zinc oxide coated urea
    Patent number: 3941578
    Abstract: Urea particles uniformly coated with zinc oxide having excellent adherence and uniformity of the zinc oxide coating are obtained by using a zinc oxide composition characterized by having a purity of 90 to 99% zinc oxide and a uniform particle size of at least 90% smaller than 12 microns and at least 95% smaller than 37 microns. Outstanding coatings are obtained if the zinc oxide composition additionally contains traces of carbon, iron oxide, magnesium oxide, or calcium oxide. High zinc-content coatings of excellent uniformity and adherence may be obtained with these coating compositions.
