Metallurgical Product Description
Silicon carbideyog insoluble nyob rau hauv dej, thiab muaj ob feem ntau siv ntau yam: dub silicon carbide thiab ntsuab silicon carbide. Silicon carbide yog ib qho carbide nrhiav pom nyob rau hauv chav kuaj los ntawm American Acheson xyoo 1891 thaum lub sij hawm fused pob zeb diamond sim. Lub sijhawm ntawd, Acheson tab tom sim npaj pob zeb diamond. Thaum nws rhaub av nplaum (aluminosilicate) thiab hmoov coke (carbon) nyob rau hauv ib lub tais hlau, xiav crystals tsim. Lub sijhawm ntawd, nws yuam kev xav tias lawv yog cov pob zeb diamond sib xyaw, yog li ntawd nws thiaj li hu ua emery.

Daim ntawv thov
Silicon carbide deoxidizer yog ib hom tshiab ntawm cov muaj zog sib xyaw deoxidizer nrog cov nyhuv deoxidation zoo heev, uas ua rau lub sijhawm deoxidation luv, txuag lub zog, txhim kho steelmaking efficiency, txo cov khoom siv, txo cov pa phem, thiab txhim kho kev ua haujlwm. Cov khoom siv no muaj txiaj ntsig zoo rau kev txhim kho cov txiaj ntsig kev lag luam ntawm cov hluav taws xob hluav taws xob.
Vim nws cov corrosion kuj, kub-resistant, thiab thermal conductivity, silicon carbide yuav siv tau nyob rau hauv ntau yam smelting furnace linings, high-temperature furnace Cheebtsam, silicon carbide daim hlau, liners, txhawb, saggers, silicon carbide crucibles, thiab lwm yam. Tsis tas li ntawd, silicon carbide kuj tseem tuaj yeem siv los ua cov khoom siv cua kub tsis ncaj rau hauv kev lag luam uas tsis yog-ferrous hlau smelting, xws li txhuas electrolytic hlwb, tooj liab melting rauv hauv ob sab phlu, thermocouple tiv thaiv raj, thiab lwm yam .; nws yog siv los ua qib siab silicon carbide ceramics uas hnav-tiv taus thiab kub-resistant cov ntaub ntawv; nws tseem tuaj yeem ua rau hauv lub foob pob hluav taws xob, roj turbine hniav, thiab lwm yam. Tsis tas li ntawd, silicon carbide kuj yog ib qho ntawm cov khoom siv zoo tshaj plaws rau lub hnub ci dej rhaub ntawm txoj kev loj, aviation runways, thiab lwm yam.
Silicon carbide muaj cov khoom zoo heev xws li cov thermal conductivity, loj bandgap, siab electron saturation mobility tus nqi, thiab siab tseem ceeb heev tawg hluav taws xob teb. Nws cov khoom zoo tshaj plaws them nyiaj rau qhov tsis txaus ntawm cov khoom siv semiconductor thiab cov cuab yeej siv hauv kev siv tswv yim. Nws yog dav siv hauv tsheb fais fab thiab kev sib txuas lus hauv xov tooj ntawm tes. Chips thiab lwm qhov chaw muaj kev cia siab rau kev thov dav dav. Vim tias SiC muaj kev ntseeg siab dua, kev ua haujlwm siab dua, qhov me me, thiab qhov hluav taws xob ntau dua tuaj yeem siv tau, nws tuaj yeem siv rau hauv cov khoom siv hluav taws xob xws li lub rooj tsav tsheb loj, lub tsheb chargers, thiab lub zog hluav taws xob, uas tuaj yeem txhim kho kev ua tau zoo thiab kev ua haujlwm ntawm lub tsheb fais fab. .
