Kungani i-Boron Nitride isetshenziswa kabanzi ezinhlelweni zokugcoba ezishisa kakhulu
Isakhiwo kanye nokumelana nokushisa kwe-Boron Nitride Powder
Ungathembela ku-boron nitride powder ukuze igcine isakhiwo sayo ngisho noma ibhekene nokushisa okukhulu. Ifomu eliyi-hexagonal, elivame ukubizwa ngokuthi "i-white graphite," liyinika uhlaka oluqinile noluzinzile. Lesi sakhiwo sisiza i-powder ukuthi imelane nokuqhekeka emazingeni okushisa aphezulu. Ukubona lokhu ekhonweni layo lokusingatha ukushisa okufika ku-3000 °C emoyeni we-nitrogen kanye nokufika ku-2000 °C ezimweni ezingathathi hlangothi. I-powder iphinde ifane ne-quartz ekukhuleni kokushisa kodwa ine-conductivity yokushisa ephindwe kayishumi. Lokhu kusho ukuthi isakaza ukushisa ngokushesha nangokulinganayo, okuvikela imishini yakho ekushiseni ngokweqile.
Nasi ithebula elibonisa ukuthi i-boron nitride powder ivelele kanjani ekumelaneni nokushisa kanye nezakhiwo zokushisa:
| Impahla | Inani |
|---|---|
| Ukuqhuba kwe-thermal | Iphakeme ngokuphindwe kayishumi kune-quartz |
