Yakakurumbira Sayenzi Horizons | muNyika yeTellurium

1. [Sumo]
Tellurium chinhu chinonzi quasi-metallic chine chiratidzo cheTe. Tellurium icrystal-white crystal yerhombohedral series, soluble in sulfuric acid, nitric acid, aqua regia, potassium cyanide uye potassium hydroxide, isinganyunguriki mumvura inotonhora uye inopisa uye carbon disulfide. High purity tellurium yakawanikwa nekushandisa tellurium poda seyakabikwa uye kubvisa uye kunatswa ne sodium polysulfide. Kuchena kwaive 99.999%. Ye semiconductor mudziyo, alloys, makemikari mbishi zvinhu uye maindasitiri ekuwedzera akadai sesimbi yakakandwa, rabha, girazi, nezvimwe.

2. [Zvakasikwa]
Tellurium ine maviri allotropy, anoti, dema poda, amorphous tellurium uye silvery chena, metallic luster, uye hexagonal crystalline tellurium. Semiconductor, bandgap 0.34 ev.
Pakati pemaviri allotropy of tellurium, imwe icrystalline, metallic, silvery-white uye brittle, yakafanana neantimony, uye imwe iamorphous powder, yakasviba grey. Medium density, yakaderera kunyungudika uye kuvira. Haisi simbi, asi inoita kupisa nemagetsi zvakanyanya. Pakati pevamwe vayo vese vasiri simbi, ndiyo yakanyanya simbi.

3. [Chikumbiro]
High purity tellurium single crystal rudzi rutsva rwe infrared material. Conventional tellurium inowedzerwa kune simbi uye mhangura alloys kuvandudza machinability yavo uye kuwedzera kuoma; muchena simbi yakakandwa, yakajairika tellurium inoshandiswa se carbide stabilizer kuita kuti pasi ive yakaoma uye isingapfeke; lead, iyo ine diki diki yetellurium, inowedzerwa kune alloy kuti ivandudze machinability uye kuwedzera kuoma kwayo, inovandudza kusadzikiswa kwekuora kwezvinhu, kupfeka kusagadzikana uye simba, uye inoshandiswa sesheath yetambo dzepasi pemvura; kuwedzera tellurium kutungamirira kunowedzera kuoma kwayo, uye inoshandiswa kugadzira mahwendefa ebhatiri uye mhando. Tellurium inogona kushandiswa sechinhu chinowedzera petroleum cracking catalysts uye sechigadziriso chekugadzirira ethylene glycol. Tellurium oxide inoshandiswa se colorant mugirazi. High purity tellurium inogona kushandiswa sechinhu chinosanganisa muthermoelectric zvinhu. Bismuth telluride chinhu chakanaka chefiriji. Tellurium ndiyo Rondedzero yezvigadzirwa zve semiconductor zvine akati wandei macommunication, senge cadmium telluride, mumasero ezuva.
Parizvino, indasitiri ye cdte yakaonda firimu solar simba iri kukura nekukurumidza, iyo inoonekwa seimwe yeanovimbisa simba rezuva tekinoroji.
