  • Method of making heat and impact resistant composite ceramic material
    Patent number: 5554328
    Abstract: The invention provides a ceramic composite material which includes 50-90% boron carbide, 5-30% silicon carbide, and 3-22% titanium carbide. All constituents are in powder form, and have a particle size of between 1 and 40 microns, and a purity of at least 97%. The powdered constituents are blended and consolidated by either hot isostatic pressing (HIPing) or by hot pressing, although blanks of less quality can be formed by mere sintering.
    Type: Grant

  • Fire-resistant and thermal shock-resistant composite ceramic material and method of making same
    Patent number: 5500394
    Abstract: The invention provides a ceramic composite material which includes 60-85% silicon carbide, 4-15% titanium carbide, 4-20% titanium boride, 4-13% aluminum oxide, and 1-8% titanium oxide. All constituents are in powder form, and have a particle size of between 1 and 40 microns, and a purity of at least 97%. The powdered constituents are blended and consolidated by sintering, although either hot isostatic pressing (HIPing) or by hot pressing can be used to improve certain properties such as impact resistance.
