Sayansi Yodziwika Kwambiri | mu Dziko la Tellurium

1. [Mau Oyamba]
Tellurium ndi chinthu chachitsulo chokhala ndi chizindikiro cha Te. Tellurium ndi galasi loyera ngati siliva la mndandanda wa rhombohedral, losungunuka mu sulfuric acid, nitric acid, aqua regia, potassium cyanide ndi potassium hydroxide, losasungunuka m'madzi ozizira ndi otentha komanso carbon disulfide. Tellurium yoyera kwambiri idapezeka pogwiritsa ntchito ufa wa tellurium ngati zopangira ndi kutulutsa ndi kuyenga ndi sodium polysulfide. Kuyera kwake kunali 99.999%. Pa chipangizo cha semiconductor, alloys, mankhwala opangira ndi zowonjezera zamafakitale monga chitsulo choponyedwa, rabara, galasi, ndi zina zotero.

Tellurium ili ndi allotropy ziwiri, zomwe ndi ufa wakuda, tellurium yopanda mawonekedwe ndi yoyera yasiliva, kunyezimira kwachitsulo, ndi tellurium ya hexagonal crystalline. Semiconductor, bandgap 0.34 ev.
Mwa mitundu iwiri ya tellurium, imodzi ndi yofiira, yachitsulo, yoyera ngati siliva komanso yofooka, yofanana ndi antimony, ndipo inayo ndi ufa wosaoneka bwino, imvi yakuda. Yochepa, yosungunuka pang'ono komanso yowira. Sichitsulo, koma imatulutsa kutentha ndi magetsi bwino kwambiri. Pa mitundu yonse ya tellurium, ndi yachitsulo kwambiri.

Krustalo imodzi ya tellurium yoyera kwambiri ndi mtundu watsopano wa zinthu za infrared. Tellurium yoyera kwambiri imawonjezeredwa ku zitsulo ndi mkuwa kuti iwonjezere mphamvu ya makina awo ndikuwonjezera kuuma; mu chitsulo choyera, tellurium yoyera imagwiritsidwa ntchito ngati chokhazikika cha carbide kuti pamwamba pake pakhale wolimba komanso wosawonongeka; lead, yomwe ili ndi tellurium yochepa, imawonjezeredwa ku alloy kuti iwonjezere mphamvu ya makina ake ndikuwonjezera kuuma kwake, imawonjezera kukana dzimbiri kwa zinthuzo, kukana kuvala ndi mphamvu, ndipo imagwiritsidwa ntchito ngati chivundikiro cha zingwe zam'madzi; kuwonjezera tellurium ku lead kumawonjezera kuuma kwake, ndipo kumagwiritsidwa ntchito kupanga mbale za batri ndi mtundu wake. Tellurium ingagwiritsidwe ntchito ngati chowonjezera cha ma catalyst osweka mafuta komanso ngati chothandizira kukonzekera ethylene glycol. Tellurium oxide imagwiritsidwa ntchito ngati utoto mugalasi. Tellurium yoyera kwambiri ingagwiritsidwe ntchito ngati gawo lophatikiza muzinthu za thermoelectric. Bismuth telluride ndi chinthu chabwino choziziritsira. Tellurium ndi Mndandanda wa zinthu za semiconductor zokhala ndi mankhwala angapo a telluride, monga cadmium telluride, m'maselo a dzuwa.
Pakadali pano, makampani opanga mphamvu ya dzuwa ya cdte thin film akukula mofulumira, zomwe zimaonedwa ngati imodzi mwa ukadaulo wodalirika kwambiri wa mphamvu ya dzuwa.
