ABSTRACT:
A method of producing extruded ceramic products by extruding a ceramic forming material through an extruding opening, includes a step of coating a liquid, which is nonvolatile at ordinary room temperatures, on a surface of an extruded ceramic product. The liquid is preferably coated on the surface with the aid of capillary action. An apparatus for producing extruded ceramic products includes a forward end portion having an extruding opening for extruding a ceramic forming material and a guide passage for introducing the ceramic forming material into the extruding opening, a liquid supply section provided on the forward end portion for supplying a liquid, which is nonvolatile at ordinary room temperatures, to an outer surface of a product of the ceramic forming material extruded from the extruding opening, and a liquid supply device for supplying the liquid to the liquid supply section.
