Arụmọrụ
The TIG-BiTe-P/N-2 thermoelectric ingot na-eto na alloy nke Bi, Sb, Te, Se, pụrụ iche doping na anyị pụrụ iche crystallizing usoro.The Bi2Te3 dabeere na thermoelectric ingot na-eto n'ụzọ pụrụ iche na kacha maka ime ka thermoelectric modul na-eji n'ịtụgharị okpomọkụ isi sitere na 100 ℃ (373K) ka 350 ℃ (623K) n'ime ọkụ eletrik.N'ozuzu, nkezi ọnụ ọgụgụ nke uru ZT nke ụdị p-ụdị anyị na n-ụdị ingots karịrị okpomọkụ 300K ruo 600K karịrị 0.7.The modul mere na ndị dị otú ahụ ingots nwere ike nweta 5% arụmọrụ na 250 ℃ Delta T. Ka ọ dịgodị, anyị ingot na-apụta na ezi n'ibu ike na ukwuu kwụsiri ike ihe onwunwe, na-enye isi nkume maka amị elu arụmọrụ na a pụrụ ịdabere na ike ọgbọ modul.
