Abstract
Gelcasting of ceramic components with the soldium alginate (Na-Alginate) as gelformers has received increasing attention. The aim of the present study is to improve the flexural strength of green body gelcast from nontoxic Na-alginate system by introducing a proper amount of water-soluble polymer, PVP. The rheological properties and gelling characteristics of PVP–Na-Alginate/Al2O3 suspensions were examined. Ceramic parts with uniform and homogeneous structure were fabricated as well as flexural strength and microstructure of the gelcast green and sintered bodies were highlighted.
