Kuj paub, qhov twg tellurium pom nyob rau hauv lub ntiaj teb no?

Tellurium yog tam sim no nyob rau hauv lub ntiaj teb crust tsuas yog nyob rau hauv hais txog 0.001 qhov chaw ib lab. Tellurium Cov zaub mov muaj xws li calaverite, sylvanite thiab tellurite. Nws kuj yog pom uncombined nyob rau hauv qhov, tab sis tsuas yog heev tsawg. Nws tau txais kev lag luam los ntawm cov av nkos anode tsim thaum lub sij hawm electrolytic refining tooj liab.

Kuj Paub, dab tsi yog tellurium ntawm chav tsev kub? Tellurium yog ib yam khoom ntawm chav kub , thiab nws feem ntau tuaj raws li tsaus, grey hmoov. Nrog rau kev ua crystalline thiab silver-dawb, lub caij no muaj qhov kub thiab txias thiab melting point.

Raws li txoj cai, tellurium feem ntau pom nyob qhov twg?

Qhov chaw ntawm Tellurium qhia yog feem ntau pom raws li calaverite, cov telluride kub, thiab kuj ua ke nrog lwm yam hlau. Nws yog pom ua lag luam nyob rau hauv electrolytic refining ntawm blister tooj liab los ntawm anode av nkos thaum lub sij hawm tus txheej txheem. Nws yog qee zaus pom nyob rau hauv nws haiv neeg lub xeev.

Puas yog tib neeg lub cev siv tellurium?

Hauv tib neeg thiab lwm yam tsiaj, tellurium muaj tsis paub txog kev lom neeg lub luag hauj lwm, tab sis cov cev ua metabolise nws los tsim cov volatile gaseous compound, dimethyl telluride, (CH3)2Te, uas yog tawm hauv hws thiab exhaled, thiab yog lub hauv paus ntawm charmingly potent "qej ua tsis taus pa", zoo ib yam li dab tsi tshwm sim nrog selenium ingestion.
