HT-1650C is a 1650°C max. Bridgman furnace for directional solidification and single crystal growth with a boule size up to Ø37mm.The vertical furnace has three independently controlled heating zones with a total heating length of 300 mm to set up different temperature gradients for crystal growth.STA-1650C keeps the melt stationary while moving the furnace up to control the temperature gradient, ensuring the stability of the growth interface.
