Abstract
A method of manufacturing shaped bodies from ceramic or glass, in which a green body is formed from the starting material for the shaped body in the form of a plastic mass consisting of microdispersed solid particles and water as a dispersing liquid and, if necessary, a binder, after which said green body is dried and sintered, the still wet green body being immersed in water miscible organic liquid having a lower surface tension and a lower enthalphy of vaporization than water, until the water in the green has at least largely been replaced by the organic liquid due to diffusion.
Claims9
A method of manufacturing a shaped ceramic body comprising:
- (a) shaping into a desired shape a wet green body formed of a plastic mass comprising microdispersed solid particles and water as a dispersing liquid;
- (b) immersing said shaped wet green body in a water-miscible organic liquid having a lower surface tension and a lower heat of vaporization than water, until the water in the green body has at least been substantially replaced by the organic liquid, and then
- (c) drying and sintering said shaped body.
