摘　　要：研究了采用新体系的陶瓷悬浮体的分散性、流变行为、固化特性以及坯体的抗弯强度。The dispersion of the Al2O3 powder in a water solution that contained PVA （Pohyviny 1 alcohol） was investigated. The rheological and gelling behavior of the alumina suspension in the new system were studied along with the flexural strength and microstructure of the gelcast green and sintered bodies.
