Silicon Nitride Ceramic

Silicon nitride ceramics (Si3N4)

Silicon nitride ke ceramic e bohlooho e nang le bothata bo phahameng ba ho robeha, ho hanyetsa mocheso o matla haholo, le thepa e batlang e sa kenellehe ho litšepe tse qhibilihisitsoeng.

U sebelisa litšoaneleho tsena, e sebelisoa ho likarolo tsa enjene e tukang ka hare joalo ka likarolo tsa enjene ea koloi, li-nozzles tsa mochini oa welding blowpipe, joalo-joalo, haholo likarolo tse hlokang ho sebelisoa libakeng tse thata joalo ka ho futhumatsa.

Ka khanyetso ea eona e phahameng ea ho roala le matla a phahameng a mochini, lits'ebetso tsa eona ho roala likarolo, li-bearings tse potolohang tsa shaft le lisebelisoa tsa tlhahiso ea semiconductor li ntse li eketseha.
