High Throughput Crystal Growth System By Zone Melting up to 1700C - SKJ1600HT

SKJ1600HT is a high throughput crystal growth system for metallic alloys via an induction heated zone melting method. A multi-hole graphite crucible with a thermal insulation layer is put in 5" quartz tube. 25 KW ultra-high-frequency induction coil will move from bottom to top slowly and melt and solidify multi-rod with different compositions into a single crystal. This system also can be used as zone melting purification and thermal gradient heat treatment
