Kev txhim kho ntawm cov khoom siv silicon carbide muaju thiab khoom siv

Tuam Tshoj yog cov neeg tsim khoom loj tshaj plaws thiab xa tawm ntawm cov roj silicon carbide hauv lub ntiaj teb, nrog lub peev xwm ncav cuag 2.2 lab tons, cheem ntau dua 80% ntawm tag nrho ntiaj teb. Txawm li cas los xij, ntau qhov kev muaj peev xwm nthuav tawm thiab kev saib xyuas ntau tshaj ua rau cov kev siv muaj peev xwm tsawg dua 50%. Nyob rau xyoo 2015, qhov tso zis silicon carbide hauv Suav tau tag nrho 1,02 lab tons, nrog kev siv tus nqi tsuas yog 46.4%; Xyoo 2016, tag nrho cov khoom tsim tawm tau kwv yees kwv yees li 1.05 lab tons, nrog rau kev siv tus nqi ntawm 47.7%.
Txij li Tuam Tshoj lub tshuab roj silicon carbide export raug muab tshem tawm, Tuam Tshoj cov silicon carbide export ntim loj hlob sai heev thaum xyoo 2013-2014, thiab tended kom ruaj khov thaum xyoo 2015-2016. Nyob rau xyoo 2016, Tuam Tshoj cov khoom siv silicon carbide tuaj txog 321,500 tons, nce 2,1% xyoo rau xyoo; nyob rau, Ningxia cov lag luam xa tawm ntau npaum li cas rau 111,900 tons, suav 34.9% ntawm tag nrho cov xa tawm thiab ua raws li lub ntsiab silicon carbide tus xa khoom hauv Suav teb.
Raws li lub teb chaws Suav silicon carbide cov khoom lag luam feem ntau yog cov khoom lag luam qis ua ntej nrog cov khoom muaj nqi nruab nrab, qhov sib txawv tus nqi nruab nrab ntawm kev xa tawm thiab ntshuam yog loj heev. Xyoo 2016, Tuam Tshoj cov silicon carbide xa tawm muaj cov nqi nruab nrab ntawm USD0.9 / kg, tsawg dua li 1/4 ntawm tus nqi nruab nrab ntshuam (USD4.3 / kg).
Silicon carbide yog siv dav hauv hlau & hlau, refractories, ceramics, photovoltaic, hluav taws xob thiab lwm yam. Xyoo tsis ntev los no, silicon carbide tau muab tso rau hauv tiam thib peb ntawm cov khoom siv semiconductor ua qhov kub kub ntawm lub ntiaj teb R & D thiab kev siv. Hauv xyoo 2015, lub ntiaj teb silicon carbide substrate kev ua lag luam loj tau txog kwv yees USD111 lab, thiab qhov loj ntawm silicon carbide zog khoom siv tau ncav cuag li USD175 lab; ob ntawm lawv yuav pom qhov nruab nrab txhua xyoo kev nce qib ntau dua 20% hauv tsib xyoos tom ntej.
Tam sim no, Tuam Tshoj tau ua tiav R & D ntawm semiconductor silicon carbide, thiab paub txog cov khoom lag luam loj ntawm 2-nti, 3-nti, 4-nti thiab 6-nti silicon carbide monocrystalline substrates, silicon carbide epitaxial wafers, thiab silicon carbide Cheebtsam Cov. Cov tuam txhab sawv cev muaj xws li TanKeBlue Semiconductor, SICC Cov Khoom Siv, EpiWorld International, Dongguan Tianyu Semiconductor, Thoob Ntiaj Teb Fais Fab Technology thiab Nanjing SilverMicro Electronics.
Niaj hnub no, kev txhim kho ntawm cov khoom siv silicon carbide muaju thiab cov cuab yeej siv tau tsim nyob rau hauv Suav Tebchaws 2025, Cov Khoom Siv Kev Tsim Kho Khoom Siv Tshiab, Kev Qhia Txog Kev Lag Luam Hauv Tebchaws Nruab Nrab thiab Nthuav Dav thiab Kev Kawm Txuj Ci (2006-2020) thiab lwm yam kev cai lij choj ntxiv. Tsav los ntawm ntau txoj cai muaj txiaj ntsig thiab kev lag luam tawm tshiab xws li lub zog tsheb tshiab thiab daim phiaj hluav taws xob ntse, Suav cov khoom lag luam semiconductor silicon carbide yuav pom cov kev txhim kho sai tom ntej.
