Description

Microwave sintering studies with boron carbide (B{sub 4}C) are being evaluated to compare properties of unidirectionally pressed and sintered microwaved pellets with gelcasting of B{sub 4}C. The particle blend is a 50/50 blend of 1-{micro}m and 0.1-{micro}m using 5 wt% carbon (Thermax{reg_sign}) addition. The large, dual-frequency microwave furnace was used to determine that scaleup of a large number of parts can be processed simultaneously using a microwave furnace. Microwave heat treatment of commercial silicon carbide (SiC) resulted in minimal densification, which is thought to result from the exclusion of liquid-phase eutectic, producing sintering aids.
