Ku saabsan Tellurium Dioxide
Natiijada ugu weyn ee ka dhalata gubashada tellurium ee hawada waa tellurium dioxide. Tellurium dioxide si dhib yar ayuu ugu milmi karaa biyaha laakiin si buuxda ayuu ugu milmi karaa aashitada sulfuric ee xooggan. Tellurium dioxide waxay muujinaysaa xasillooni darro leh aashito xooggan iyo oksaydh awood leh. Maadaama tellurium dioxide uu yahay maaddo amphoteric ah, waxay ka fal celin kartaa aashito ama alkaline oo ku jirta xalka.
Maadaama tellurium dioxide ay leedahay fursad aad u sarreysa oo ay ku keento qaab-dhismeed xumo waana sun, marka uu jirka galo, waxay soo saari kartaa ur (urta tellurium) oo la mid ah urta toonta ee neefta ku jirta. Noocan walaxdu waa dimethyl tellurium oo ay soo saarto dheef-shiid kiimikaadka tellurium dioxide.
