Nrov Science Qab Zib | Rau Hauv Lub Ntiaj Teb Ntawm Tellurium

1. [Taw qhia]
Qhia me ntsis yog ib qho Qasi-Metallic caij nrog lub cim Te. Qhia tawm cov nyiaj-dawb ntawm rhombohedral series, soluble hauv sulfburic acid, nitricium cynrows, insoluble nyob rau hauv dej txias thiab dej kub thiab carbon disulfide. Kev Purity Heev tau txais los ntawm kev siv Tovurium hmoov zoo li cov khoom siv raw thiab rho tawm thiab ua kom zoo dua nrog sodium polysulfide. Lub purity yog 99.999%. Rau semiconductor ntaus ntawv, alloys, tshuaj raw cov ntaub ntawv thiab kev siv tshuaj ntxiv xws li cam khwb cia hlau, roj hmab, iav, thiab lwm yam iav, thiab lwm yam.

Cov ntaub ntawv qhia tau muaj ob feem ntau, hmoov dub, amorphous seldurium thiab sivertaluvuter, thiab hexagonal crystalline qhia. Shamiconductor, bandgap 0.34 ev.
Ntawm ob feem ntawm cov lus qhia, yog xim hlau, sithallic, zoo ib yam li cov hmoov txhuas, thiab lwm yam yog hmoov zoo, tsaus grey. Nruab nrab ceev, tsawg melting thiab boiling point. Nws yog qhov tsis ua haujlwm, tab sis nws ua thaum kub thiab hluav taws xob zoo heev. Ntawm tag nrho nws cov khub uas tsis yog xim hlau, nws yog xim hlau tshaj plaws.

Kev Purity Turelurium High Sensurium Ib Crystal yog ib hom khoom tshiab ntawm infrared. Cov lus qhia qhia ntxiv rau cov hlau thiab cov tshuab loj los txhim kho lawv lub tshuab luam ntawv thiab nce kev nyuaj; Hauv dawb cam khwb cia hlau, cov pa qhia tas yog siv los ua lub carbide stabilizer kom lub saum npoo tawv thiab hnav-resistant; Txhuas, uas muaj me me ntawm selurium, yog ntxiv rau lub alloy los txhim kho nws cov khoom siv tsis khov, thiab siv los ua lub txaj rau subeatrine cable; Ntxiv cov lus qhia rau cov hmoov txhuas ua rau nws lub hardness, thiab yog siv los ua roj teeb phaj thiab hom. Cov ntaub ntawv qhia tuaj yeem siv los ua cov roj av ntxiv rau cov portalum tawg thiab ua ib qho kev ua yeeb yam rau kev npaj ntawm ethylene glycol. Cov tshuaj tiv thaiv oxide yog siv los ua cov xim hauv iav. Kev pham purity showurium tuaj yeem siv los ua kev sib xyaw ua ke hauv thermoelectric ntaub ntawv. Bismuth qhia rau yog cov khoom siv txias. Qhia rau cov ntaub ntawv semiconductor nrog ntau cov lus teb qhia, xws li cadmium qhia, hauv cov hlwb sollmium.
Tam sim no, kev lag luam ntawm CDTE nyias zaj duab xis hnub ci zog yog tsim kom sai, uas tau pom tias yog ib qho kev cog lus ntau tshaj plaws thev naus laus zis.
