I-China ingumkhiqizi nomthumeli omkhulu kunabo bonke we-silicon carbide emhlabeni, ngomthamo ofinyelela kumathani ayizigidi ezingama-2.2, ushanela ngaphezu kuka-80% wengqikithi yomhlaba jikelele. Kodwa-ke, ukwanda kwamandla amaningi ngokweqile nokusebenzisa ngokweqile kuholela ekusetshenzisweni komthamo ngaphansi kwama-50%. Ngo-2015, ukukhishwa kwe-silicon carbide eChina kwafinyelela kumathani ayizigidi eziyi-1.02, ngesilinganiso sokusetshenziswa komthamo sika-46.4% kuphela; ngo-2016, inani lokukhishwa lalinganiselwa kumathani ayizigidi eziyi-1.05, ngesilinganiso sokusetshenziswa komthamo esingu-47.7%.
Kusukela ukuqedwa kwesilinganiso se-silicon carbide eChina, ivolumu yokuthekelisa ye-silicon carbide yaseChina ikhule ngokushesha phakathi kuka-2013-2014, futhi ithambekele ekuqineni phakathi kuka-2015-2016. Ngo-2016, ukuthunyelwa kwamanye amazwe kwe-silicon carbide yaseChina kwafika kumathani ayi-321,500, kukhuphuke ngo-2.1% unyaka nonyaka; lapho, ivolumu yokuthekelisa yaseNingxia yaba ngamathani ayi-111,900, ebalwa ngama-34.9% wokuthekelisa okuphelele futhi esebenza njengomthumeli omkhulu we-silicon carbide eChina.
Njengoba imikhiqizo ye-silicon carbide yaseChina ikakhulukazi iyimikhiqizo esetshenzisiwe esezingeni eliphansi enenani elingeziwe elingeziwe, igebe lentengo eliphakathi kokuthekelisa nokungenisa likhulu kakhulu. Ngo-2016, ukuthunyelwa kwe-silicon carbide yaseChina kwaba nentengo emaphakathi ku-USD0.9 / kg, ngaphansi kuka-1/4 wentengo emaphakathi yokungenisa (USD4.3 / kg).
I-silicon carbide isetshenziswa kakhulu ku-iron nensimbi, ama-refractories, i-ceramics, i-photovoltaic, i-electronics njalonjalo. Eminyakeni yamuva nje, i-silicon carbide ifakiwe esizukulwaneni sesithathu sezinto ze-semiconductor njengendawo eshisayo ye-R & D yomhlaba nezinhlelo zokusebenza. Ngo-2015, usayizi wemakethe yomhlaba we-silicon carbide substrate wafinyelela cishe ezigidini ezingama-USD111, futhi ubukhulu bamadivayisi kagesi we-silicon carbide afinyelela cishe kwizigidi ezingama-USD175; bobabili bazobona isilinganiso sokukhula sonyaka esingaphezu kuka-20% eminyakeni emihlanu ezayo.
Njengamanje, iChina iphumelele ku-R & D ye-semiconductor silicon carbide, futhi yaqaphela ukukhiqizwa okukhulu kwamasentimitha ama-2-intshi, ama-intshi ama-3, ama-intshi ama-4 ne-6-intshi we-silicon carbide monocrystalline, ama-silicon carbide epitaxial wafers, kanye nezinto ze-silicon carbide . Amabhizinisi amele abandakanya iTanKeBlue Semiconductor, izinto ze-SICC, i-EpiWorld International, iDongguan Tianyu Semiconductor, iGlobal Power Technology kanye neNanjing SilverMicro Electronics.
Namuhla, ukwakhiwa kwamakristalu namadivayisi e-silicon carbide kuqukethwe kwi-Made in China 2025, i-New Material Industry Development Guide, i-National Medium and Long-term Science and Technology Development Plan (2006-2020) nezinye izinqubomgomo eziningi zezimboni. Iqhutshwa yizinqubomgomo eziningi ezithandekayo nezimakethe ezisafufusa njengezimoto ezintsha zamandla negridi ehlakaniphile, imakethe yaseChina yama-semiconductor silicon carbide izofakazela intuthuko esheshayo ngokuzayo.
