Txog Tellurium Dioxide
Qhov tshwm sim tseem ceeb ntawm tellurium hlawv hauv huab cua yog tellurium dioxide. Tellurium dioxide tsis tshua yaj hauv dej tab sis tuaj yeem yaj tag nrho hauv cov kua qaub sulfuric concentrated. Tellurium dioxide qhia txog kev tsis ruaj khov nrog cov kua qaub muaj zog thiab cov tshuaj oxidant muaj zog. Vim tellurium dioxide yog cov khoom amphoteric, nws tuaj yeem ua rau cov kua qaub lossis alkaline hauv cov tshuaj.
Vim tias tellurium dioxide muaj feem ua rau muaj kev puas tsuaj thiab lom, thaum nqus mus rau hauv lub cev, nws tuaj yeem tsim cov ntxhiab tsw (tsw ntxhiab tellurium) zoo ib yam li cov ntxhiab qej hauv cov pa. Hom khoom no yog dimethyl tellurium uas tsim los ntawm kev ua haujlwm ntawm tellurium dioxide.
