  • Process and installation for making extruded sintered ceramic artifact
    Patent number: 6063323
    Abstract: A process and installation are provided for making an extruded sintered ceramic product. The method involves extruding a moist profile and simultaneously drying it with microwave radiation as it is extruded. As the profile is extruded and dried, it is supported at a position where it has been at least partially dried. The installation comprises extrusion means for extruding a moist profile, support means for supporting the extruded profile at an at least partially dried part thereof, and a microwave radiation source for directing microwaves at the profile.

  • Method of drying a porous body
    Patent number: 5979073
    Abstract: A method of making a dried porous ceramic body having interconnected surface pores and interior channels. The body is formed by extrusion from a paste and is irradiated with microwave radiation to heat it for an initial period at a rate of at least 15.degree. C./minute, after which the irradiation is reduced so that the body is heated at a rate of at most 1.degree. C./minute. Heat loss from the external surface of the body, during heating, is resisted.
