  • Method and apparatus for the sintering and condensation of ceramic compacts
    Patent number: 4830607
    Abstract: A compact to be sintered is moved vertically through a zone in which it is heated locally above its sintering temperature. The body is supported at both its top and bottom ends so that the area being sintered at a given time is not exposed to stress due to the weight of the body. Apparatus includes an oven casing having inductive heating means about a sintering zone therein, a lower lifting system on which the compact is supported, and an upper pulling system for lifting the top of the compact.
