A na-ejikarị crucibles carbon-carbon eme ihe na sistemu ọkụ dị ka ọkụ ọkụ ọkụ fotovoltaic na semiconductor kristal.
Isi ọrụ ha bụ:
1. Ọrụ ibu ọkụ dị elu:A ga-edobe crucible quartz nke jupụtara na akụrụngwa polysilicon n'ime ikuku carbon/carbon. Carbon/carbon crucible ga-ebu ibu nke quartz crucible na polysilicon akụrụngwa iji hụ na akụrụngwa agaghị awụpụ mgbe oke okpomọkụ quartz crucible dị nro. Tụkwasị na nke ahụ, a ghaghị iburu ihe ndị ahụ na-eme ka ọ gbanwee n'oge usoro ịdọrọ kristal. Ya mere, a na-achọrọ akụrụngwa akụrụngwa ka ọ dị oke elu;
2. Ọrụ nnyefe ọkụ:The crucible na-eduzi okpomọkụ a chọrọ maka agbaze nke polysilicon akụrụngwa site na ya magburu onwe okpomọkụ conductivity. Okpomọkụ na-agbaze bụ ihe dịka 1600 ℃. Ya mere, crucible ga-enwe ezigbo okpomọkụ okpomọkụ;
3. Ọrụ nchekwa:Mgbe a na-emechi ọkụ ọkụ na mberede, a ga-enwe nrụgide dị ukwuu na crucible n'ime obere oge n'ihi mmụba olu nke polysilicon n'oge oyi (ihe dịka 10%).
Atụmatụ nke VET Energy's C/C crucible:
1. Ịdị ọcha dị elu, obere volatility, ọdịnaya ash <150ppm;
2. High okpomọkụ na-eguzogide, ike nwere ike nọgidere na-enwe ruo 2500 ℃;
3. Ọmarịcha arụmọrụ dị ka nguzogide corrosion, iyi nguzogide, acid na alkali resistance;
4. Ọnụ ọgụgụ mgbasawanye ọkụ dị ala, ike na-eguzogide okpomọkụ;
5. Ezigbo ihe eji arụ ọrụ okpomọkụ dị elu, ogologo ndụ ọrụ;
6. Ịnabata echiche nhazi n'ozuzu, ike dị elu, usoro dị mfe, ịdị arọ dị arọ na ọrụ dị mfe.
