Cov ntaub ntawv tshiab tshaj plaws yog qhov zoo dua li yav dhau los thiab lawv tau nrov heev nrog ntau tus neeg siv khoom.
Cov khoom ntawm recrystallized silicon carbide
Recrystallized silicon carbide (R-SiC) yog cov khoom siv ua haujlwm siab nrog hardness thib ob rau pob zeb diamond, uas yog tsim los ntawm qhov kub siab tshaj 2000 ℃. Nws khaws ntau yam khoom zoo ntawm SiC, xws li kub siab zog, muaj zog corrosion kuj, zoo heev oxidation kuj, zoo thermal shock kuj thiab lwm yam.
● Cov khoom siv kho tshuab zoo heev. Recrystallized silicon carbide muaj lub zog ntau dua thiab nruj dua li cov pa roj carbon fiber ntau, muaj kev cuam tshuam siab, tuaj yeem ua haujlwm zoo hauv qhov kub thiab txias, tuaj yeem ua si qhov kev ua tau zoo dua hauv ntau qhov xwm txheej. Tsis tas li ntawd, nws kuj muaj qhov hloov tau zoo thiab tsis yooj yim puas los ntawm kev ncab thiab khoov, uas ua rau nws ua tau zoo heev.
● High corrosion kuj. Recrystallized silicon carbide muaj kev tiv thaiv corrosion siab rau ntau yam xov xwm, tuaj yeem tiv thaiv kev yaig ntawm ntau yam corrosive media, tuaj yeem tswj nws cov khoom siv rau lub sijhawm ntev, muaj zog adhesion, kom nws muaj lub neej ntev kev pab cuam. Tsis tas li ntawd, nws kuj muaj qhov zoo thermal stability, tuaj yeem hloov kho rau qee qhov kev hloov pauv ntawm qhov kub thiab txias, txhim kho nws daim ntawv thov.
● Sintering tsis ntsws. Vim tias cov txheej txheem sintering tsis ntsws, tsis muaj kev ntxhov siab seem yuav ua rau deformation lossis tawg ntawm cov khoom, thiab cov khoom nrog cov duab nyuaj thiab siab precision tuaj yeem npaj tau.

Khoom piav qhia:
Peb zoo siab los qhia koj txog cov khoom lag luam uas tsim los ntawm Semicera Energy Technology Co., Ltd. - Semiconductor SiCNkoj Wafer. Raws li ib tug ua lag luam tshwj xeeb hauv wafers thiab advanced semiconductor consumables, peb tau cog lus los muab cov neeg muas zaub nrog cov khoom zoo, txhim khu kev qha. , thiab thawb cov khoom tshiab rau semiconductor manufacturing, photovoltaic kev lag luam thiab lwm yam kev lag luam.
Semiconductorsilicon carbide wafer nkojs yog tsim los siv recrystallized silicon carbide (R-SiC), cov khoom ua tau zoo nrog cov khoom tshwj xeeb. Cov khoom siv tau pom tau los ntawm cov txheej txheem kub siab tshaj 2000 ° C, thiab muaj qhov zoo tshaj plaws hardness thib ob tsuas yog pob zeb diamond.
