  • Crucibles for a microwave sintering furnace
    Publication number: 20050211702
    Abstract: Incidents of fracturing of crucibles during microwave sintering are reduced through the use of low thermal shock resistance crucibles comprised predominately of an alloy of silicon nitride and aluminum oxide.
    Type: Application

  • Method and apparatus for transporting green work pieces through a microwave sintering system
    Patent number: 6066290
    Abstract: This disclosure sets forth a method and apparatus for microwave processing of green work pieces. Typically, individual green work pieces are formed in a small mold cavity crucible, and individual crucibles are then indexed into and out of a tube for a controlled transit time along the tube. The tube extends in one embodiment through a preheater and then into the microwave cavity, the preheater providing an initial heating step to change the rate of absorption of microwave energy so that microwave sintering is accomplished in the cavity.
    Type: Grant
