PBN Boat
Main Features:
1. Capable of producing large-sized boats (up to a maximum height of 17 inches).
2. High density (up to 2.20 g/cm³).
3. High purity (>99.99%).
4. Resistant to cracking (high interlayer strength).
5. Excellent high-temperature resistance (up to 2300°C in vacuum).
6. Good thermal shock resistance.
7. Long service life.
Product Overview: The horizontal directional solidification method is used to synthesize polycrystals. The directional solidification furnace consists of three temperature zones. Taking gallium arsenide (GaAs) polycrystals as an example, arsenic sublimates in the low-temperature zone (around 630°C), passes through the intermediate-temperature zone, and gradually reacts with gallium in the high-temperature zone (1250–1255°C) to form GaAs polycrystals. PBN boats are used as reaction vessels in the high-temperature zone.
Product Applications:
Used in horizontal directional solidification methods for growing III-V compound polycrystals and other related applications.
