abstract |
The present invention is a vinyl alcohol polymer containing 2 to 19 mol% of ethylene units, having a polymerization degree of 200 to 2,000, a saponification degree of 80 to 99.99 mol%, and a carboxylic acid and lactone ring content of 0.02 to 0.4 mol% The present invention relates to a binder for molding ceramics having a main component as a main component. By using the ceramic molding binder, it provides a green molded body having excellent moldability and handling characteristics when molding a small green molded body having a more complicated shape, and also by sintering the green molded body with excellent quality, high yield When obtained, it is possible to provide a ceramic molded body having less ceramic cracks. |
