摘要： The firing shrinkage of ceramic film casting mixtures can be increased by adding a high molecular weight mixed ester or a mixture of various high molecular weight mixed esters to them. The ceramic material of the ceramic film casting mixtures is composed preferably of lead titanate, silicon carbide, silicon nitride, beryllium oxide or aluminum oxide. Preferably, the mixed esters are derived from at least one C.sub.2 -C.sub.10 -dicarboxylic acid and at least one C.sub.8 -C.sub.24 -monocarboxylic acid. The proportion of high molecular weight mixed ester in the film casting mixture amounts to up to 5% by weight, based on the proportion of solids in the casting mixture, including sintering aids.The process makes it possible to alter the composition of a slip and still use the old tools which require an unaltered firing shrinkage.
