Mafotokozedwe Akatundu:
Silicon nitride ceramics ali ndi mwayi kuposa zitsulo pazinthu zambiri. Amagwiritsidwa ntchito kwambiri pazamlengalenga, nyukiliya, petrochemical, nsalu ndi mafakitale opanga makina.
Ubwino:
·Makina abwino kwambiri
·Kachulukidwe kochepa kwambiri
· Mphamvu zazikulu ndi kuuma
·Kugundana kocheperako
· Ntchito yabwino yopangira mafuta
·Kukana dzimbiri zachitsulo
· Kutsekereza magetsi

Silicon nitride ceramics ndizapamwamba kuposa zida zina chifukwa cha kukana kwake kugwedezeka kwamafuta. Siziwonongeka pakutentha kwambiri, chifukwa chake zimagwiritsidwa ntchito pama injini zamagalimoto ndi magawo amagetsi amagetsi, kuphatikiza turbocharger rotor.
Ortech imapereka banja lathunthu la zida za Silicon Nitride. Zidazi zili ndi zizindikiro zotsatirazi: Palibe zomatira zotsutsana ndi zitsulo, Kawiri molimba ngati chitsulo chachitsulo, Kukana kwa mankhwala abwino ndi 60% kulemera kochepa kuposa chitsulo.
Silicon nitrides (Si3N4) ndi mitundu ingapo ya zida zopangira uinjiniya zomwe zimadziwika ndi mphamvu zambiri, kulimba komanso kulimba komanso kukhazikika kwamankhwala komanso kutentha.
Silicon nitride idapezeka chapakati pazaka za m'ma 1900 koma sanabwereke kuti apange mosavuta, chifukwa cha chikhalidwe chake chogwirizana. Izi poyamba zidapangitsa kuti pakhale mitundu iwiri ya silicon nitride, reaction-bonded silicon nitride (RBSN) ndi hot pressed silicon nitride (HPSN). Pambuyo pake, kuyambira m'ma 1970 mitundu ina iwiri yapangidwa: sintered silicon nitride (SSN), yomwe imaphatikizapo ma sialons, ndi sintered reaction-bonded silicon nitride (SRBSN).
Chidwi chomwe chilipo pazida zaunjiniya za silicon nitride zidapangidwa kuchokera ku kafukufuku wazaka za m'ma 1980 kukhala magawo a ceramic a injini ya turbine ya gasi ndi pistoni. Zinkaganiziridwa kuti injini, yopangidwa makamaka kuchokera ku silicon nitride yochokera ku silicon nitride, monga sialon, idzakhala yolemera kwambiri ndipo imatha kugwira ntchito pa kutentha kwakukulu kuposa injini zachikhalidwe zomwe zimapangitsa kuti zikhale zogwira mtima kwambiri. Koma pamapeto pake, cholinga chimenechi sichinakwaniritsidwe chifukwa cha zinthu zingapo kuphatikizapo mtengo wake, kuvutika popanga mbalizo modalirika komanso kuwonongeka kwa chilengedwe cha zoumba.
Komabe, ntchitoyi idapangitsa kuti pakhale ntchito zina zambiri zamafakitale zopangira zida za silicon nitride, monga kupanga zitsulo, kuvala kwa mafakitale ndi kunyamula zitsulo zosungunuka.
Mitundu yosiyanasiyana ya silicon nitride, RBSN, HPSN, SRBSN ndi SSN, imachokera ku njira yawo yopangira, yomwe imayendetsa katundu wawo ndi ntchito zawo.
