The slip casting studies on well optimised slips of Sic, Si3N 4 and silicon have been applied to fabricate some components with complicated shapes eg. after burner catalytic ignitor housings, super charger stator rings etc. The green densities of slip cast bodies of Sic, Si3N4 and silicon slips ranges from 50 to 60 of theoretical value, indicating that good compacts can be obtained by the slip casting procedure by using these optimised slips
