CYKY-BG1500 is a Bridgman furnace with the maximum temperature of 1500℃. It is designed for the directional solidification of Polycrystalline Ingots up to 25mm diameter. The heating module & cooling fan with adjustable speed is beneficial to create a large temperature gradient at the interface of the molten / crystalline state. An automatic crucible retrieving system enables the most convenient way for sample loading/unloading. The optional crucible rotation stage can be added at additional cost for single crystal ingot growth.

Technical parameters:
