Continuous pusher-type furnacing system for the production of high-quality uniform boron nitride |
摘要 |
A process for continuously manufacturing boron nitride utilizing a graphite capsule/vessel container for the reaction mixture and a pusher-type of high-temperature furnace. The process comprises the steps of: a) during the preheat step: pushing the graphite capsule/vessel through hot zones such that the reacting mixture is heated uniformly throughout its cross-sectional area and is held at or below 1000° C.: b) during the ultra-high-temperature heating step: pushing the graphite capsule/vessel through hot zones such that the reacting mixture is heated uniformly throughout its cross-sectional area and is held in the range of 1600 to 2200° C.
