  • For the process control of silicon nitride gelcasting, the effect of MeOH on the apparent gel induction time of slip, drying rate, and mechanical property of gelcast body were investigated. The apparent gel induction time showed maximum at 10~20 vol% MeOH and the drying rate of gelcast body increased in the ranged of 25~40%. The gelcast body was still machinable in the 40% of MeOH, though the mechanical property and relative density slightly decreased with increasing the amount of MeOH.
