Introduction
The crystal growth furnace is suitable for Bridgman method (crucible descent method), crystal growth under vacuum, protective atmosphere, or oxidizing atmosphere.
It can store up to 15 sets of process curves, including temperature, gas flow rate, crystal feeding speed (crystal growth rate), and can be switched arbitrarily. When crystal growth is complete, it provides alarm prompts, generates experiment reports, and exports data (including but not limited to temperature, gas flow rate, feeding rate, etc.).
Main Features
1. Unique internal gradient temperature zone program for easily finding required temperature gradients.
2. Grating ruler for real-time sample position detection and accurate measurement of sample displacement.
3. Unique high-low-speed switching mode for easy sample handling and satisfying both low-speed and high-speed crystal growth operations. Speed is continuously adjustable, with crystal growth speed ranging from 30 to 20,000 um/h.
