Silicon carbide fata pepa o se vaega autu o loʻo faʻaaogaina i faʻagasologa o gaosiga semiconductor. Matou te faʻaogaina a matou tekonolosi pateni e fai ai le fata pepa kalisikoni ma le mama maualuga, lelei faʻapipiʻiina tutusa ma se olaga sili ona lelei, faʻapea foʻi ma le maualuga o vailaʻau faʻamaʻi ma mea e mautu ai le vevela.
VET Energy o le gaosiga moni o graphite ma silicon carbide oloa faʻapipiʻi eseese e pei o SiC, Tac, pyrolytic carbon, tioata tioata, ma isi, e mafai ona tuʻuina atu vaega faʻapitoa mo semiconductor ma photovoltaic alamanuia. O la matou 'au fa'atekinisi e sau mai fa'alapotopotoga su'esu'e fa'apitonu'u pito i luga, e mafai ona tu'uina atu fa'afitauli fa'apitoa fa'apitoa mo oe.
O lo'o fa'aauau pea ona matou fa'atupuina faiga fa'agasolo e tu'uina atu ai mea e sili atu ona maualuga, ma ua fa'atinoina se tekonolosi pateni fa'apitoa, lea e mafai ona fa'amalosia atili ai le so'otaga i le va o le fa'apipi'i ma le mea fa'apipi'i ma fa'aitiitia ai le fa'ateteleina.
Vaega oa tatou oloa:
1. maualuga le vevela oxidation tetee atu i le 1700 ℃.
2. maualuga mama ma vevela tutusa
3. Lelei le fa'afefeteina: acid, alkali, masima ma meaola fa'aola.
4. Maaa maualuga, faʻapipiʻi luga, vaega laiti.
5. Le soifua tautua umi ma sili atu le umi
