ʻO Kina ka mea nui a hoʻopuka o ka silicon carbide ma ka honua, me ka hiki i 2.2 miliona mau tona, ka nui o 80% o ka huina o ka honua. Eia nō naʻe, hoʻonui nui i ka hiki a hoʻonui i ka oversupply alakaʻi i ka hiki ke hoʻohana ma lalo o 50%. I ka makahiki 2015, he 1.02 miliona mau tona o ka silicon carbide i hoʻopuka ʻia ma Kina, me ka helu o ka hiki ke hoʻohana ʻia he 46.4% wale nō; i ka 2016, ua hoʻohālikelike ʻia ka huina huahana e pili ana i 1.05 miliona mau tona, me ka hiki ke hoʻohana ʻia me 47.7%.
Ma muli o ka hoʻopau ʻia ʻana o ka quota hoʻoilina silikone carbide a Kina, ua ulu wikiwiki ka nui o ka lawe ʻia ʻana o kā silicon carbide export i ka makahiki 2013-2014, a ua hoʻomau ʻia e hoʻokūpaʻa ma waena o 2015-2016. I ka 2016, ua lawe ʻia mai kā Kina mau kālika silikona i 321,500 tone, a i 2.1% makahiki i ka makahiki; kahi o, Ningxia ka nui o ka hoʻolilo ʻana i lilo i 111,900 mau tona, e helu ana no 34.9% o ka huina o nā mea hoʻolilo a ke hana nei ma ke ʻano he mea hoʻopuka nui silikona carbide ma Kina.
ʻOiai ʻo nā huahana silicon carbide a Kina ke kumu haʻahaʻa i hana mua ʻia me nā huahana i hoʻonui ʻia me ka waiwai i hoʻohui ʻia, nui ka awelike kumukūʻai ma waena o ka lawe aku a lawe mai. I ka makahiki 2016, ua loaʻa i ko Kina mau silikona carbide waiwai kūʻai ke kumukūʻai awelika ma USD0.9 / kg, ma lalo o 1/4 o ke kumukūʻai awelika lawe ʻia (USD4.3 / kg).
Hoʻohana nui ʻia ka silicon carbide i ka hao & kila, nā mea hoʻopili, nā pālolo, nā photovoltaic, nā uila uila a pēlā aku. I nā makahiki i hala iho nei, ua hoʻokomo ʻia ka silicon carbide i ke kolu o ka hanauna o nā mea semiconductor ma ke ʻano he wahi wela o ka honua R & D a me nā noi. I ka 2015, ua hōʻea ka nui o ka mākeke silikone karbide substrate honua ma kahi o USD111 miliona, a ua hōʻea ka nui o nā hāmeʻa silicon carbide ma kahi o USD175 miliona; e ʻike lāua ʻelua i ka awelika o ka ulu ulu makahiki ma mua o 20% i nā makahiki ʻelima e hiki mai ana.
I kēia manawa, ua kūleʻa ʻo Kina i ka R & D o ka semiconductor silikone carbide, a ʻike i ka hana nui o 2-inch, 3-inch, 4-inch a me 6-inch silicon carbide monocrystalline substrates, silicon carbide epitaxial wafers, a me silicon carbide partide . ʻO nā ʻoihana ʻāpana e komo pū me TanKeBlue Semiconductor, SICC Materials, EpiWorld International, Dongguan Tianyu Semiconductor, Global Power Technology a me Nanjing SilverMicro uila uila.
I kēia lā, ʻo ka hoʻomohala ʻana o nā aniani kilika silika a me nā hāmeʻa i loaʻa i Hana ʻia ma Kina 2025, Kahi Alakaʻi Hoʻolālā ʻĀpana Hou, National Medium a me ka Hoʻolālā Hoʻolālā ʻEpekema a me Ke Keʻena Hana Nui (2006-2020) a me nā kulekele ʻenehana ʻē aʻe. Kipaku ʻia e nā kulekele maikaʻi a me nā mākeke e kū mai nei e like me nā kaʻa ikehu hou a me ka mākia akamai, e ʻike maka koke ʻia ka mākeke silikone semiconductor silikone carbide i ka wā e hiki mai ana.
