I-Silicon Carbide Ceramics kanye ne-Silicon Nitride Ceramics

Uhlolojikelele lweI-Silicon Carbide Ceramics
I-silicon carbide ceramics iwuhlobo olusha lwe-ceramic material eyenziwe ngokuyinhloko nge-silicon carbide powder ngokusebenzisa i-high-temperature sintering. I-silicon carbide ceramics inobulukhuni obuphezulu, ukumelana nokugqoka, ukumelana nokugqwala, kanye nokumelana okuhle kakhulu nezinga lokushisa eliphezulu, okunemishini emihle kakhulu, eshisayo, kanye nezakhiwo zikagesi. Izitsha zobumba ze-silicon carbide zingahlukaniswa zibe izitsha ezihlanganisiwe ze-silicon carbide ceramics kanye ne-reaction sintered silicon carbide ceramics ngenxa yezinqubo ezahlukene zokudubula.

Uhlolojikelele lwe-Silicon Nitride Ceramics
I-Silicon nitride ceramics iyimpahla ebalulekile ye-ceramic esebenza kahle kakhulu. Inezici ezinhle kakhulu zemishini, ukumelana nokushisa okuphezulu, ukumelana nokugqwala, kanye ne-thermal conductivity. Uma kuqhathaniswa ne-silicon carbide ceramics, i-silicon nitride ceramics izinzile. I-silicon nitride ceramics inobulukhuni obuphakeme kakhulu namandla, ngakho-ke isetshenziswa kabanzi ekukhiqizeni izimboni kanye nokwenza imishini enembile ngaphansi kwezinga lokushisa eliphezulu nengcindezi.
Umehluko phakathi kwe-silicon carbide ceramics kanye ne-silicon nitride ceramics
1. Izakhiwo ezahlukene
Isakhiwo se-silicon carbide ceramics sakhiwe ngamandla okubopha phakathi kwezinhlamvu ze-silicon carbide, kuyilapho ukwakheka kwe-silicon nitride ceramics yakhiwe ngamabhondi e-silicon nitrogen akhiwa i-silicon nama-athomu e-nitrogen. Ngakho-ke, izitsha zobumba ze-silicon nitride zizinzile kune-silicon carbide ceramics.
2. Ukusetshenziswa okuhlukile
Izitsha zobumba ze-silicon carbide zivame ukusetshenziswa ezindaweni zokwelapha ukushisa okushisayo, njengezindwangu zokushisa ukushisa, amafasitela okubuka embonini ye-semiconductor, nezinkambu zokucubungula imishini. Ama-ceramics e-silicon nitride asetshenziswa kakhulu ekusikeni, ekugayeni, ekufakweni kukagesi, ekuvikelweni nakwezinye izinkambu ngaphansi kokushisa okuphezulu nezimo zokucindezela okukhulu embonini yokukhiqiza.
3. Ukusebenza okuhlukile
I-Silicon carbide ceramics inezakhiwo ezinhle kakhulu zokushisa okuphezulu, ukumelana nokuguga, kanye nezindawo ezivimbela ukugqwala, kuyilapho izitsha zobumba ze-silicon nitride azinayo nje kuphela izinga lokushisa eliphezulu, ukumelana nokuguga, kanye nezakhiwo ezivimbela ukugqwala, kodwa futhi nokuhamba kahle kwe-thermal kanye nezakhiwo zokuvala ugesi, ngakho-ke zingasetshenziswa ezinhlobonhlobo ezibanzi zezinkambu.
Ngamafuphi, nakuba kokubili i-silicon carbide ceramics kanye ne-silicon nitride ceramics kungokwezinto zokwakha ze-ceramic ezisebenza kahle, izakhiwo zazo, izinhlelo zokusebenza, kanye nezakhiwo zihlukile. Abasebenzisi kudingeka bakhethe izinto ezifanele ngokwezidingo zabo.
