  • Hollow borosilicate microspheres and method of making
    Patent number: 5534348
    Abstract: The present invention provides hollow borosilicate microspheres having a mean particle size between 15 and 20 microns, and a true density below 0.25 g/cc. The invention also provides a method for making such microspheres comprising spray drying a solution of sodium silicate and sodium borate in a spray tower to form a precursor, milling the precursor, and heating the crushed precursor to a temperature in excess of 600.degree. F. to form hollow borosilicate microspheres.

  • Process for the production of alkali metal chlorites
    Patent number: 4087515
    Abstract: Alkali metal chlorites are produced by the reaction of chlorine dioxide with an alkali metal amalgam in a reaction mixture where the pH is maintained at from about 9.5 to about 11.5 by providing an excess of the alkali metal to the chlorine dioxide of at least 10 mole percent.Alkali metal chlorites obtained by this process are free of insoluble mercury and have reduced concentrations of soluble mercury as a contaminant.
