Ucoceko oluphezulu lweArsenic

Inkcazo

Ucoceko oluphezulu lweArsenicI-5N 6N 7N, ikristale enombala omdaka kunye nesilivere-ngwevu okanye i-amorphous metalloid eqinileyo enobunzima be-athomu yi-74.92, ubuninzi be-5.73g/cm³, indawo yokunyibilika i-817 ° C, eyona nto izinzile kwiqondo lokushisa lokushisa, inokusabela ngetsimbi, izinto ezingenayo i-metallic, i-alkali kunye ne-oxidizing acid, kodwa ingaphenduli nge-hydrochloric acid.Ucoceko oluphezulu lwe-arsenic lunokuhlanjululwa ngaphezu kwe-99.999%, 99.9999% kunye ne-99.99999% yococeko nge-hydrogen atmosphere vacuum sublimation, i-chlorination, i-distillation kunye nokunciphisa iinkqubo zokucoca njl.I-High Purity Arsenic 5N 6N 7N kwi-Western Minmetals (SC) I-Corporation ecocekileyo ye-99.999% 99.9999% kunye ne-99.99999% inokuhanjiswa ngobukhulu be-2-7mm, 2-10mm, 3-25mm iqhuma elingaqhelekanga, elipakishwe nge-1 kg. I-1.5kg kwibhotile yeglasi ye-Schott enegesi ye-argon ezaliswe, i-vacuum yeplastiki yeplastiki ngaphandle, okanye njengengcaciso elungiselelwe ukufikelela kwisisombululo esigqibeleleyo.

Usetyenziso

I-Arsenic ye-High Purity isetyenziswa ngokuyinhloko ekwenzeni i-alloys ephezulu yokucoceka, i-III-V i-semiconductors edibeneyo efana ne-Gallium Arsenide GaAs kunye ne-Indium Arsenide InAs, i-glass semiconductor, iityhubhu ze-electron, izinto ze-welding transistor, izixhobo zoqhagamshelwano ezichanekileyo, kunye nentonga yokulawula ye-atomic reactor. kwaye isetyenziswe njenge-dopant ye-silicon kunye ne-germanium yokukhula kwekristale enye.
