China ndi yomwe imapanga komanso kugulitsa kwambiri silicon carbide padziko lapansi, yomwe imatha kufikira matani 2.2 miliyoni, ikusesa kuposa 80% yapadziko lonse lapansi. Komabe, kukulitsa mphamvu zochulukirapo komanso kupitirira muyeso kumabweretsa kugwiritsidwa ntchito kosachepera 50%. Mu 2015, ndi silikoni carbide linanena bungwe ku China okwana matani miliyoni 1.02, ndi mphamvu mphamvu ya ntchito 46.4% okha; mu 2016, linanena bungwe okwana pafupifupi pafupifupi mamiliyoni 1.05 miliyoni, ndi mphamvu mphamvu ntchito 47.7%.
Popeza kuti gawo la China silicon carbide logulitsa kunja lidathetsedwa, voliyumu yakunyumba yaku China yotumiza kunja idakulirakulira mwachangu mu 2013-2014, ndipo idakhazikika nthawi ya 2015-2016. Mu 2016, zogulitsa kunja ku China za carbide zidafika matani 321,500, mpaka 2.1% pachaka; momwe, kuchuluka kwa kunja kwa Ningxia kunafika matani 111,900, kuwerengera 34,9% yazogulitsa zonse ndikukhala ngati wogulitsa wamkulu wa silicon carbide ku China.
Monga mankhwala a silicon carbide aku China ali makamaka otsika kumapeto omwe amasinthidwa kale ndi mtengo wowonjezera wowonjezera, kusiyana pakati pamitengo pakati ndi kutumizira kunja ndi kwakukulu. Mu 2016, China yotumiza pakachitsulo ya carbide inali ndi mtengo wapakati pa USD0.9 / kg, yochepera 1/4 yamtengo wapakatikati (USD4.3 / kg).
Pakachitsulo carbide chimagwiritsidwa ntchito chitsulo & chitsulo, refractories, ziwiya zadothi, photovoltaic, zamagetsi ndi zina zotero. M'zaka zaposachedwa, silicon carbide yaphatikizidwa m'badwo wachitatu wa zida zama semiconductor ngati malo otentha a R & D yapadziko lonse lapansi ndi ntchito. Mu 2015, kukula kwa msika wa silicon carbide substrate pamsika kudafika pafupifupi USD111 miliyoni, ndipo kukula kwa zida zamagetsi zamagetsi za silicon zidafika pafupifupi USD175 miliyoni; Onsewa adzawona kuchuluka kwapachaka kwapakati pa 20% pazaka zisanu zikubwerazi.
Pakadali pano, China yakwanitsa kupanga R & D ya semiconductor silicon carbide, ndikuzindikira kuchuluka kwa magawo awiri-inchi, 3-inchi, 4-inchi ndi 6-inchi silicon carbide monocrystalline substrates, silicon carbide epitaxial wafers, ndi silicon carbide . Mabizinesi oimira monga TanKeBlue Semiconductor, SICC Materials, EpiWorld International, Dongguan Tianyu Semiconductor, Global Power Technology ndi Nanjing SilverMicro Electronics.
Lero, kupangidwa kwa makhiristo ndi zida za silicon carbide zapezeka mu Made in China 2025, Buku Lopanga Zida Zamakampani, National Medium and Long-term Science and Technology Development Plan (2006-2020) ndi njira zina zambiri zamakampani. Yoyendetsedwa ndi mfundo zingapo zabwino ndi misika yomwe ikubwera kumene monga magalimoto atsopano amagetsi ndi gridi yanzeru, msika waku China semiconductor silicon carbide udzawona chitukuko chamtsogolo mtsogolo.
