Induction

A Lely-type furnace utilizing 10 kHz induction heating has proved to have significant advantages over resistance-heated furnaces for the growth of high quality α-SiC crystals. A massive graphite susceptor, with good thermal isolation from the cooled parts of the furnace, can be used. This design leads to low thermal gradients and freedom from hot spots — conditions ideal for reproducible
