Claicon Nitride: Qoob-ka-noole weyn oo silicon ah

Silicon Nitride waa shey muhiim u ah qaab dhismeedka qaab dhismeedka, oo lagu garto xasilloonida kuleylka sare, iska caabin adag, iyo sax ahaanta muuqaalka sare. Crystal atomic ah, waa shey heer sare ah oo leh saliido dhasha oo xidho iska caabbinta. Waxay ka dhagartaa oksidation heerkulka sare waxayna u adkeysan kartaa shoogga kuleylka. Waxaa lagu kululayn karaa hawada ilaa in ka badan 1000 ° C, ka dibna si dhakhso ah loo qaboojiyey oo lagu kululaaday iyada oo aan dillaacin.

Claitriquics-ka Silicon Nitride waa kuleylka u adkaysta, sii wadida xoog sare iyo adkaanta heerkulka ilaa 1400 ° C (inkasta oo ay xoog makaanikeyntu ka hooseyso 1200 ° C). Si kastaba ha noqotee, iyagu waa kuwo jajaban. Munaasabyo fiber ah oo joogto ah ayaa loo isticmaalaa in laga helo qaybaha marawaxadaha, gaar ahaan birta iyo dhagaxa kore, iyo sidoo kale hawada hawada ee matoorada yaryar. Intaa waxaa sii dheer, cufnaantooda gaarka ah ee gaarka ah, kaliya 41% taasi oo ka mid ah tiirarka birta, waxay si weyn u yareyn kartaa culeyska matoorrada diyaaradaha oo ay wanaajinayaan hufnaanta shidaalka.
