发明名称 PRODUCTION OF CERAMICS
摘要 PURPOSE:To prevent cracking and crazing during the production of dry gel, to shorten the drying time and to enable the formation of largesized ceramics when ceramics is produced by a sol-gel process by carrying out conversion into gel in the presence of a water soluble polymer. CONSTITUTION:A metal alkoxide is hydrolyzed, the resulting hydrolyzate is converted into gel and this gel is dried and sintered to produce ceramics. At this time, the conversion into gel is carried out in the presence of a water soluble polymer. The polymer is preferably used by 0.1-10wt.% of the amt. of the metal alkoxide. The polymer may be PVA, sodium polyacrylate, polyethylene oxide, polyethylene glycol, starch, gelatin or gum arabic.
