Fa'amatalaga Puupuu:

O le WeiTai Energy Technology Co., Ltd. ose kamupani ta'uta'ua e fa'apitoa i mea fa'atau ma semiconductor.Matou te faʻamaoni i le tuʻuina atu o oloa maualuga, faʻatuatuaina, ma faʻafouina i le gaosiga o semiconductor, alamanuia photovoltaic ma isi faʻalapotopotoga faʻapitoa.

O la matou laina oloa e aofia ai SiC / TaC faʻapipiʻiina oloa graphite ma oloa sima, e aofia ai mea eseese e pei o le silicon carbide, silicon nitride, ma le alumini oxide ma isi.

I le taimi nei, ua na oi matou le gaosiga e tuʻuina atu le mama 99.9999% SiC coating ma le 99.9% recrystallized silicon carbide.Ole umi ole umi ole SiC e mafai ona tatou faia 2640mm.

Auina imeli ia matou

Fa'amatalaga Oloa

Faailoga o oloa

Silicon carbide (SiC) mea tioata tasi o loʻo i ai le lautele o le va tele (~ Si 3 taimi), conductivity vevela maualuga (~ Si 3.3 taimi po o GaAs 10 taimi), maualuga eletise saturation fua faatatau (~ Si 2.5 taimi), eletise malepe maualuga. fanua (~ Si 10 taimi po o GaAs 5 taimi) ma isi uiga mataʻina.

O masini SiC e le mafai ona suitulaga i le tulaga o le maualuga o le vevela, maualuga o le mamafa, maualuga le tele o taimi, masini eletise eletise ma faʻalavelave faʻapitoa tau le siosiomaga e pei o le aerospace, militeri, malosi faaniukilia, ma isi, faʻaoga mo le faaletonu o masini semiconductor masani i le aoga. talosaga, ma ua faasolosolo malie lava ona avea ma tulaga autu o eletise eletise.
