Pyrolytic Boron Nitride Samfuran PBN
Bayanin Samfura
Pyrolytic Boron Nitride (PBN) an ƙirƙira shi ta hanyar sanannen tsari na Chemical Vapor Deposition (CVD) wanda iskar ammonia (NH3) da gaseous boron halide irin su boron trichloride (BCI3) ke amsawa a cikin tanderun CVD mai zafi don ajiya. PBN akan madaidaicin madauri kamar Pyrolytic Graphite.
An san PBN a matsayin kyakkyawan zaɓi don tanderun zafin jiki da kayan aikin lantarki, semiconductor, da lu'ulu'u na microwave kamar germanium (Ge), gallium arsenide (GaAs), da indium phosphate (InP) saboda tsabtar sa na ciki, ingantaccen kayan aikin injiniya. , da kwanciyar hankali na physicochemical. PBN na iya jure wa 1800°C a sarari da 2000°C a cikin nitrogen, yana gabatar da shi azaman zaɓi mai kyau don abubuwan tanderu da tasoshin narkewa.
