Horizons Sayensị ewu ewu | n'ime ụwa nke Tellurium

1. [Okwu mmalite]
Tellurium bụ ihe na-acha ọla edo nwere akara Te. Tellurium bụ kristal ọlaọcha na-acha ọcha nke usoro rhombohedral, soluble na sulfuric acid, nitric acid, aqua regia, potassium cyanide na potassium hydroxide, nke na-adịghị ike na mmiri oyi na mmiri ọkụ na carbon disulfide. Enwetara tellurium dị ọcha dị elu site n'iji tellurium ntụ ntụ dị ka ihe eji eme ihe na ịwepụta na imezi ya na sodium polysulfide. Ịdị ọcha bụ 99.999%. Maka ngwaọrụ semiconductor, alloys, akụrụngwa kemịkalụ na mgbakwunye ụlọ ọrụ dị ka nkedo, roba, iko, wdg.

2. [Nature]
Tellurium nwere allotropy abụọ, ya bụ, ntụ ntụ ojii, amorphous tellurium na ọlaọcha na-acha ọcha, luster metal, na hexagonal crystalline tellurium. Semiconductor, bandgap 0.34 ev.
N'ime allotropy abụọ nke tellurium, otu bụ crystalline, ọla, ọlaọcha-acha ọcha na kenkuwa, yiri antimony, na nke ọzọ bụ amorphous ntụ ntụ, ọchịchịrị isi awọ. Ọkara njupụta, obere agbaze na ebe esi. Ọ bụ igwe anaghị agba nchara, mana ọ na-eduzi ọkụ na ọkụ eletrik nke ọma. N'ime ndị enyi ya niile na-abụghị ọla, ọ bụ ihe kacha mma.

Ịdị ọcha tellurium otu kristal bụ ụdị ihe infrared ọhụrụ. A na-agbakwunye tellurium omenala na ígwè na ọla kọpa alloys iji mee ka ọrụ ha dịkwuo mma ma mụbaa ike; na ígwè nkedo na-acha ọcha, a na-eji tellurium omenala eme ihe dị ka carbide stabilizer iji mee ka elu ahụ sie ike ma ghara iyi; ndu, nke nwere obere tellurium, a na-agbakwunye ya na alloy iji meziwanye machinability ya ma mee ka ike ya dịkwuo elu, ọ na-eme ka ihe mgbochi corrosion nke ihe ahụ dịkwuo mma, na-eyi nguzogide na ike, ma jiri ya mee ihe dị ka mkpuchi maka eriri ụgbọ mmiri; ịgbakwụnye tellurium na ndu na-abawanye ike ya, a na-ejikwa ya emepụta efere batrị na ụdị. Enwere ike iji Tellurium mee ihe dị ka ihe mgbakwunye maka ndị na-agbawa mmanụ ala yana dị ka ihe na-akpali maka nkwadebe nke ethylene glycol. A na-eji Tellurium oxide mee ihe dị ka agba na iko. Enwere ike iji tellurium dị ọcha dị ka ihe na-eme ka ihe na-ekpo ọkụ na-ekpo ọkụ. Bismuth telluride bụ ezigbo ihe nju oyi. Tellurium bụ ndepụta nke ihe semiconductor nwere ọtụtụ ogige telluride, dị ka cadmium telluride, na sel anyanwụ.
Ka ọ dị ugbu a, ụlọ ọrụ nke cdte thin film ike anyanwụ na-etolite ngwa ngwa, nke a na-ewere dị ka otu n'ime teknụzụ ike anyanwụ na-ekwe nkwa.
