Silicon nitride yakasungirirwa silicon carbide
Si3N4 yakasungirirwa SiC ceramic refractory material, yakasanganiswa nepamusoro yakachena SIC poda yakatsetseka uye Silicon poda, mushure mekutsvedza kukanda kosi, kuita sintered pasi pe1400 ~ 1500 ° C.Munguva yekupisa, kuzadza iyo yakakwira yakachena Nitrogen muchoto, ipapo silicon ichaita neNitrogen uye inogadzira Si3N4, Saka Si3N4 yakasungirirwa SiC zvinhu inoumbwa nesilicon nitride (23%) uye silicon carbide (75%) sechinhu chikuru mbishi. , yakasanganiswa ne organic material, uye yakaumbwa nemusanganiswa, extrusion kana kudira, yozoitwa mushure mekuoma uye nitrogenization.
Zvimiro uye zvakanakira:
1.High tembiricha kushivirira
2.High thermal conductivity uye shock resistance
3.High mechanical simba uye abrasion resistance
4.Excellent simba rekushandisa uye kusagadzikana kwekuora
Isu tinopa emhando yepamusoro uye nemachini akagadzirwa NSiC ceramic zvikamu izvo zvinogadzira
1.Slip casting
2.Extruding
3.Uni Axial Pressing
4.Isostatic Pressing

WeiTai Energy Technology Co., Ltd. inotungamira mutengesi wemhando yepamusoro semiconductor ceramics uye chete mugadziri muChina anogona panguva imwe chete kupa yakakwirira-kuchena silicon carbide ceramic (kunyanya iyo Recrystallized SiC) uye CVD SiC coating.Pamusoro pezvo, kambani yedu yakazvipirawo kuminda yeceramic yakadai sealuminium, aluminium nitride, zirconia, uye silicon nitride, nezvimwe.
Zvigadzirwa zvedu zvikuru zvinosanganisira: silicon carbide etching disc, silicon carbide boat tow, silicon carbide wafer boat (Photovoltaic & Semiconductor), silicon carbide furnace chubhu, silicon carbide cantilever paddle, silicon carbide chucks, silicon carbide beam, pamwe neCVD SiC coating uye TaC. coating.Zvigadzirwa zvinonyanya kushandiswa mu semiconductor uye photovoltaic maindasitiri, senge midziyo yekukura kwekristaro, epitaxy, etching, kurongedza, kupfekedza uye diffusion furnaces, nezvimwe.
Kambani yedu ine yakakwana yekugadzira michina senge kuumba, sintering, kugadzirisa, coating midziyo, nezvimwewo, iyo inogona kupedzisa ese anodiwa malink ekugadzirwa kwechigadzirwa uye kuve nepamusoro kutonga kwemhando yechigadzirwa;Iyo yakakwana chirongwa chekugadzira chinogona kusarudzwa zvinoenderana nezvinodiwa zvechigadzirwa, zvichikonzera kuderera kwemutengo uye kupa vatengi zvigadzirwa zvinokwikwidza;Isu tinokwanisa kuchinjika uye zvine hungwaru kuronga kugadzirwa kwakavakirwa pane odha yekutumira zvinodiwa uye takabatana neyepamhepo odha manejimendi masisitimu, ichipa vatengi nekukurumidza uye yakavimbiswa nguva yekutumira.
