Studies on Gelcasting of Alumina Matrix Ceramic

Abstract

Abstract: The gelcasting of α-alumina and binary zirconia-alumina composites ceramic was further studied. Special emphasis was placed on the preparation and gelation
of concentrated suspension with low viscosity and high solide volume loading. By using dispersant MN made in our laboratory, basic α-alumina concentrated
suspension whose solide loading as high as 65Vol% while viscosity as low as 267 mPa·s was prepared, besides,basic 10Vol% zirconia(3Y)-alumina concentrated
suspension with 55Vol% solide loading and low viscosity was prepared. The properties of gelcasting body were also studied.

Key words: gelcasting, α-alumina, zirconia(3Y)-alumina, suspension,electrosteric stabilization
