  • Ceramic igniters and process for making same
    Patent number: 5191508
    Abstract: A process for producing a ceramic igniter comprising forming a slot in a green igniter body prior to densification and inserting into the slot an electrically non-conductive material is described. In addition, a ceramic igniter containing a slot insert produced by the process of the invention is disclosed. The inventon is particularly directed to single and double hairpin-shaped igniters.

  • Method for the preparation of sinterable nitrides
    Patent number: 4929433
    Abstract: Nitride powders of high surface area, uniform small particle size and high purity are prepared by forming in an aqueous medium a homogeneous combination of a soluble or colloidally dispersible compound of a multivalent metal with a water soluble oxygen oxygenated carbonaceous polymer, e.g., by mixing an aluminum or other metal salt with polyacrylic acid or mixing colloidal hydrated alumina, or other such metal oxide, with a water soluble oxygenated carbonaceous polymer such as sucrose or methyl cellulose. The resulting precipitate or gel is dried and calcined in a nitriding atmosphere, forming a nitride powder which is highly suitable for fabrication of ceramic bodies by sintering at lower than conventional temperatures.
