    C09K 300
  • US Classification:
    25218313
  • Abstract:
    High purity silica powder formed from a sol-gel process is made from a quantity of an industrial grade hydrolizable silicon organometallic substance mixed with a quantity of an industrial grade organic solvent miscible in said organometallic substance and with a quantity of an acidified water having a pH less than 2 to form a solution. The solution is heated, then dried to form a gel, milled, and calcined to form the pure silica powder and the pure powder used to form encapsulated micro-miniature circuits.

  • US Patent:
    51889897, Feb 23, 1993
  • Filed:
    Dec 1, 1987
  • Appl. No.:
    7/127268
  • Inventors:
    Howard M. Winkelbauer - McKeesport PA
    Eugene T. Rushe - Port Vue PA
  • Assignee:

  • US Patent:
    45336466, Aug 6, 1985
  • Filed:
    May 24, 1984
  • Appl. No.:
    6/613941
  • Inventors:
    Ke-Chin Wang - Pittsburgh PA
    Howard M. Winkelbauer - Mifflin PA
  • Assignee:
    Dresser Industries, Inc. - Dallas TX
  • International Classification:
    C04B 3558
    C04B 3518
    C04B 3510
  • US Classification:
    501 97
  • Abstract:
    This invention relates to a method for producing nitride bonded refractory shapes in which the bonding matrix is formed in situ. The method comprises forming a batch including a coarser portion selected from the group calcined and fused aggregates of alumina, aluminosilicate, and magnesium aluminate spinel and a finer portion consisting essentially of finely divided silicon metal and alumina as well as fines of the above mentioned refractory aggregate needed to achieve the desired screen analysis. The silicon metal and alumina react in the nitriding atmosphere to form a low porosity matrix generally comprising silicon oxynitride with corundum distributed therethrough.

  • US Patent:
    45006440, Feb 19, 1985
  • Filed:
    Dec 19, 1983
  • Appl. No.:
    6/562770
  • Inventors:
    Howard M. Winkelbauer - West Mifflin PA
    Kenneth W. Hill - Lynchburg VA
    Ke-Chin Wang - Pittsburgh PA
  • Assignee:
    Dresser Industries, Inc. - Dallas TX
  • International Classification:
    C04B 3558
  • US Classification:
    501 98
  • Abstract:
    Dense sialon grain is produced by briquetting mixtures of micronized silicon and reactive alumina. Sialon powder is produced by ball milling the briquettes after nitriding. The starting mixtures can contain from 10 to 38% reactive alumina with the balance of the mixture micronized silicon. Mixtures made within this range when pressed into dense briquettes and nitrided produce useful sialon grain having minimal free alumina contamination.
