Zodziwika Kwambiri za Sayansi | mu World of Tellurium

1. [Mawu Oyambirira]
Tellurium ndi chinthu chofanana ndi chitsulo chokhala ndi chizindikiro cha Te. Tellurium ndi crystal yoyera ya rhombohedral series, sungunuka mu sulfuric acid, nitric acid, aqua regia, potassium cyanide ndi potaziyamu hydroxide, osasungunuka m'madzi ozizira ndi otentha ndi carbon disulfide. High purity tellurium idapezedwa pogwiritsa ntchito ufa wa tellurium ngati zopangira ndikuchotsa ndikuyenga ndi sodium polysulfide. Kuyera kunali 99.999%. Kwa chipangizo cha semiconductor, ma aloyi, zinthu zopangira mankhwala ndi zowonjezera zamafakitale monga chitsulo choponyedwa, mphira, galasi, etc.

2. [Chilengedwe]
Tellurium ili ndi ma allotropy awiri, omwe ndi ufa wakuda, amorphous tellurium ndi silvery white, metallic luster, ndi hexagonal crystalline tellurium. Semiconductor, bandgap 0.34 ev.
Mwa allotropy awiri a tellurium, imodzi ndi crystalline, zitsulo, silvery-white ndi brittle, yofanana ndi antimoni, ndipo ina ndi ufa wa amorphous, mdima wandiweyani. Kuchulukana kwapakatikati, kusungunuka kochepa komanso kuwira. Ndi nonmetal, koma imayendetsa kutentha ndi magetsi bwino kwambiri. Mwa anzake onse omwe si achitsulo, ndi zitsulo kwambiri.

3. [Mapulogalamu]
High purity tellurium single crystal ndi mtundu watsopano wa infrared material. Telurium wamba amawonjezeredwa kuzitsulo zachitsulo ndi zamkuwa kuti apititse patsogolo machinability awo ndikuwonjezera kuuma; mu chitsulo choyera choyera, telelurium wamba imagwiritsidwa ntchito ngati chokhazikika cha carbide kuti ikhale yolimba komanso yosavala; kutsogola, komwe kuli ndi kachulukidwe kakang'ono ka tellurium, kumawonjezedwa ku aloyi kuti kuwongolera machinability ndikuwonjezera kuuma kwake, kumathandizira kukana kwa dzimbiri kwa zinthu, kukana kuvala ndi mphamvu, ndipo kumagwiritsidwa ntchito ngati mchimake wa zingwe zam'madzi; kuwonjezera tellurium kutsogolera kumawonjezera kuuma kwake, ndipo amagwiritsidwa ntchito kupanga mbale za batri ndi mtundu. Tellurium angagwiritsidwe ntchito ngati chowonjezera kwa mafuta osokoneza mafuta chothandizira ndi monga chothandizira yokonza ethylene glycol. Tellurium oxide imagwiritsidwa ntchito ngati colorant mu galasi. High purity tellurium ingagwiritsidwe ntchito ngati chigawo cha alloying mu zipangizo za thermoelectric. Bismuth telluride ndi firiji yabwino. Tellurium ndi Mndandanda wa zida za semiconductor zomwe zimakhala ndi ma telluride angapo, monga cadmium telluride, m'maselo a dzuwa.
Pakalipano, makampani a cdte filimu yopyapyala mphamvu ya dzuwa ikukula mofulumira, yomwe imatengedwa kuti ndi imodzi mwa njira zamakono zopangira mphamvu za dzuwa.
