  • Method of forming ceramic igniters
    Patent number: 5785911
    Abstract: A method for forming thin green ceramic igniter shapes having a thickness characterized by a tolerance of no more than about +/-0.001 inch includes providing an apparatus having a porous mold having a well which defines a pair of opposing porous walls, and a plurality of vertical dividers positioned in the well in substantially parallel, substantially spaced relation where each divider contacting each opposing wall to define a plurality of compartments. A ceramic slip formed from a ceramic powder and a liquid carrier is poured into the compartments of the apparatus, dewatered through the opposing porous walls to form a plurality of green ceramic igniter shapes. The plurality of green ceramic igniter shapes are removed from the plurality of compartments.

  • Silicon nitride vacuum furnace process
    Patent number: 4970057
    Abstract: An improved process of preparing silicon nitride by the direct nitridation of silicon metal is disclosed. The process is a multi-step one which is substantially more efficient than prior processes and produces a silicon nitride having an oxygen content of less than 1%, a silicon metal content of less than 0.5%, and an alpha phase content of at least 85%, preferably at least 90%. The silicon nitride may be converted to a powder.
