Abstract
Alumina bushing used for manufacturing glass fiber was fabricated by gel-casting which can fabricate complex forms. When solid loading is increased, density was increased and shrinkage and absorption were decreased. The sample loading with 57 vol% solid was optimum for alumina suspension, which showed the best physical properties. The cast sample was sintered at $1550{^{\circ}C}$ for two hours with sintering additive, $Y_2O_3$. The result showed that the alumina bushing with $Y_2O_3$ sintering additive has a density of 98%, shrinkage of 11% and bending strength of 196 kg/$cm^2$.
