Autu autu ole fa'avevela graphite:
1. tutusa o fausaga faamafanafana.
2. conductivity lelei eletise ma le mamafa eletise maualuga.
3. tete'e corrosion.
4. inoxidizability.
5. mama maualuga kemikolo.
6. malosi faʻainisinia maualuga.
O le lelei o le malosi lelei, maualuga le tau ma maualalo le tausiga. E mafai ona tatou gaosia le anti-oxidation ma le umi o le ola o le graphite crucible, graphite mold ma vaega uma o le graphite heater.

VET Malosiaga o o legaosi moni o graphite faʻapitoa ma oloa kalisika carbide faʻatasi ma le CVD coating,mafai ona sapalaieseesevaega fa'apitoa mo semiconductor ma photovoltaic alamanuia. Our vaega faʻapitoa e sau mai faʻalapotopotoga suʻesuʻe pito i luga, e mafai ona tuʻuina atu faʻamatalaga faʻapitoa faʻapitoamo oe.
Matou te faʻaauau pea ona atiaʻe faʻagasologa alualu i luma e tuʻuina atu mea e sili atu ona maualuga,maua galue i fafo se tekinolosi pateni faapitoa, lea e mafai ona faia le sootaga i le va o le ufiufi ma le substrate faʻamalosi ma faʻaitiitia ai le faʻalavelave.
Ftulaga oa tatou oloa:
1. maualuga le vevela oxidation tetee atu i le 1700℃.
2. maualuga mama matutusa vevela
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
