  • Method for preparing particulate zinc oxide shapes of high surface area and improved strength
    Patent number: 4071609
    Abstract: Particulate zinc oxide shaped of high surface area and improved crushing strength are prepared without extraneous binder by a process including forming normal surface area zinc oxide into shapes without binder, converting at least a portion of the zinc oxide to basic zinc carbonate by exposing the shapes in the presence of moisture, to a carbon dioxide-containing atmosphere and effecting substantially complete decomposition of the basic zinc carbonate. Conditions of bulk density, moisture content and temperature are controlled.
