Isitini Esiphikisayo Se-Si3N4 Esibopha Ngama-Si3N4 ngokwezifiso esimelana nokugqwala

$I-SiC Bonded Si3N4 Refractory Brick imelana nokushisa okuphezulu ngokwezifiso Isithombe Esifakiwe$

Incazelo emfushane:

I-WeiTai Energy Technology Co., Ltd. ingumphakeli ohamba phambili ogxile ekusetshenzisweni kwe-wafer kanye ne-semiconductor ethuthukisiwe.Sizinikezele ekuhlinzekeni ngemikhiqizo yekhwalithi ephezulu, ethembekile, nentsha ekukhiqizeni ama-semiconductor,imboni ye-photovoltaicnezinye izinkambu ezihlobene.

Umugqa wethu womkhiqizo uhlanganisa imikhiqizo ye-graphite ehlanganiswe ne-SiC/TaC nemikhiqizo yobumba, ehlanganisa izinto ezihlukahlukene ezifana ne-silicon carbide, i-silicon nitride, ne-aluminium oxide nokunye.

Njengomhlinzeki othembekile, siyakuqonda ukubaluleka kwezinto ezisetshenziswayo ohlelweni lokukhiqiza, futhi sizibophezele ekuletheni imikhiqizo ehlangabezana namazinga aphezulu ekhwalithi ukuze sifeze izidingo zamakhasimende ethu.

Thumela i-imeyili kithi

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-Silicon nitride ehlanganiswe ne-silicon carbide kiln inezici zamandla okushisa aphezulu, ukumelana nokushaqeka okuhle kokushisa, ukuguquguquka okulula, ukumelana ne-oxidation, ukumelana nokugqwala, ukuhamba kahle kwe-thermal nokunye.

Izinkomba zokusebenza eziyinhloko

Imikhiqizo isetshenziswa kakhulu kumasondo okugaya e-ceramic, imikhiqizo ephezulu ye-aluminium, ibhola le-aluminium porcelain, iziko lezimboni, i-ceramic kagesi, i-porcelain kagesi ephezulu, i-sanitary ware, i-porcelain yansuku zonke, i-nitride alloy kanye ne-foam ceramics nezinye izimboni.

Ukumelana nokugqokwa kwezinto ze-Si3N4-SiC izikhathi ezingu-3.13 kunensimbi engagugi (Crl5Mo3), futhi isisindo singu-1/3 kuphela waleso sensimbi engagugi (Crl5Mo3).

Amanani okunciphisa izinga lokumelana nokugqwala kwe-Si3N4-SiC ne-calcium carbide ne-alumina ezixazululweni ezihlukahlukene ami kanje:
