WeiTai Energy Technology Co., Ltd. mutengesi anotungamira anonyanya hunyanzvi mune wafer uye yepamusoro semiconductor yekushandisa.Isu takatsaurirwa kupa zvemhando yepamusoro, zvakavimbika, uye zvigadzirwa zvitsva kune semiconductor kugadzira,photovoltaic industrynemimwe minda yakabatana.

Mutsetse wedu wechigadzirwa unosanganisira SiC/TaC yakavharwa magirafu zvigadzirwa uye zvigadzirwa zveceramic, zvinosanganisira zvinhu zvakasiyana siyana sesilicon carbide, silicon nitride, uye aluminium oxide nezvimwe.

Semutengesi akavimbika, tinonzwisisa kukosha kwezvinhu zvinobatika mukugadzira, uye takazvipira kuendesa zvigadzirwa zvinosangana nemhando yepamusoro-soro yekuzadzisa zvinodiwa nevatengi vedu.

Zvigadzirwa izvi zvinoshandiswa zvakanyanya muceramic kugaya vhiri, yakakwira aluminium zvigadzirwa, aluminium porcelain bhora, honi yeindasitiri, yemagetsi ceramic, yakakwira voltage yemagetsi porcelain, sanitary ware, zuva nezuva porcelain, nitride alloy uye furo ceramics uye mamwe maindasitiri.

Kupfeka kupikisa kweSi3N4-SiC zvinhu ndeye 3.13 nguva yesimbi isingagadzirike (Crl5Mo3), uye huremu hunongova 1/3 chete yesimbi isingapfekeki (Crl5Mo3).

Iyo corrosion resistance yemhando yekudzikisa kunaka kweSi3N4-SiC uye calcium carbide uye alumina mumhinduro dzakasiyana ndeidzi:
