| abstract |
A ceramic-molding binder includes a vinyl alcohol polymer having an ethylene unit content of 2 to 19 mole %, a polymerization degree of 200 to 2,000, a degree of saponification of 80 to 99.99 mole %, and a carboxylic acid and lactone ring content of 0.02 to 0.4 mole %. The use of the ceramic-molding binder provides green moldings with better formability and handling properties during the formation of smaller green moldings of more complex shape, and also provides ceramic products of good quality, higher yields, and fewer ceramic cracks when obtained by sintering such green moldings. |
