Resistance heating type pulling system (CZ method)

Resistance heating type pulling system
Resistance heating type crystal grower
Description
This system is is the most common CZ (Czochralski) method crystal grower using the resistance heating .
Putting a seed crystal in the melt within the crucible, then grows the single crystal by pull-up and rotation.
Our ADC (Automatic Diameter Control) system controls the crystal diameter automatically.
Application
LGS、Sapphire、YAG、NdYAG、YAP、NdYAP、LuAG、YbLuAG、NdCrGSGG、BGO、PM、YVO、LBO、BSO、LSO、CaF、Si等
