| Tellurium Dioxide |
| Nambala ya CAS 7446-7-３ |
| Tellurium dioxide (chophatikizana) ndi mtundu wa oxide wa tellurium. Fomula yake ya mankhwala ndi chigawo cha TeO2. Kristalo yake ndi ya mndandanda wa makristalo okwana sikweya. Kulemera kwa mamolekyu: 159.61; ufa woyera kapena mabuloko. |
Zokhudza Tellurium Dioxide
Chotsatira chachikulu cha kuyaka kwa tellurium mumlengalenga ndi tellurium dioxide. Tellurium dioxide imatha kusungunuka m'madzi koma imatha kusungunuka kwathunthu mu sulfuric acid yokhazikika. Tellurium dioxide imasonyeza kusakhazikika ndi asidi wamphamvu komanso oxidant wamphamvu. Popeza tellurium dioxide ndi amphoteric matter, imatha kuchitapo kanthu ku asidi kapena alkaline mu yankho.
Popeza tellurium dioxide ili ndi kuthekera kwakukulu koyambitsa chilema ndipo ndi poizoni, ikalowetsedwa m'thupi, imatha kupanga fungo (fungo la tellurium) lofanana ndi fungo la adyo mumpweya. Mtundu uwu wa chinthu ndi dimethyl tellurium yomwe imapangidwa ndi kagayidwe ka tellurium dioxide.

Kodi ufa wa Tellurium Dioxide umagwiritsidwa ntchito pa chiyani?
Tellurium Dioxide (TeO₂)Ufa ndi chinthu chosapangidwa bwino chomwe chimadziwika ndi mawonekedwe ake apadera a optoelectronic, kutentha, komanso kapangidwe kake. Kusinthasintha kwake kumaphatikizapo magawo apamwamba aukadaulo, kafukufuku wasayansi, ndi kupanga mafakitale, ndi ntchito zofunika kwambiri kuphatikizapo:
1. Zipangizo za Acousto-Optic
- Imagwira ntchito ngati gawo lalikulu mu makristalo amodzi a paratellurite (α-TeO₂), zomwe zimathandiza kuti kuwala kwa ultrafast kusinthe:
✓ Chiwongolero cha laser ndi kusintha kwa ma frequency
✓ Makina olumikizirana ndi kuwala (zosefera za DWDM, ma Q-switch)
✓ Kujambula kwa ultrasound ndi holography yeniyeni
- Ikuwonetsa chithunzi chapadera cha acousto-optic figure of merit (M₂) cha zida zapamwamba zomwe zimagwira ntchito mu spectra yooneka ndi yapakati pa IR.
2. Makina Apamwamba a Magalasi
- Imagwira ntchito ngati galasi lokhazikika lomwe limapangidwa m'magalasi apadera owonera:
✓ Magalasi a tellurite opanda mphamvu zambiri a ma amplifiers a fiber (Er³+/Pr³+-doped) mu ma telecommunications
✓ Magalasi owonetsa kuwala kwa dzuwa kwambiri a magalasi a infrared ndi kuwala kwa masomphenya ausiku
✓ Galasi lozindikira kuwala kwa dzuwa la dosimetry ndi scintillation
3. Ukadaulo wa Semiconductor
- Choyambirira chofunikira cha ma semiconductor a II-VI compound:
✓ Kukula kwa makristalo a CdTe/CdZnTe kwa zozindikira za X-ray/γ-ray ndi maselo a dzuwa
✓ Kupanga kwa dot ya quantum pogwiritsa ntchito HgTe kwa ma IR photodetectors osinthika
✓ Kuphatikiza mu kafukufuku wa topological insulator (monga, Bi₂Te₃/TeO₂ heterostructures)
4. Machitidwe Osinthira Mphamvu
- Zimathandiza zipangizo zamagetsi zogwiritsira ntchito mphamvu yamagetsi zomwe zimagwira ntchito bwino kwambiri:
✓ Zosakaniza za Bismuth telluride (Bi₂Te₃) za Peltier coolers mu microelectronics
✓ Ma module obwezeretsa kutentha (ZT >1.2 pa 300-500K)
✓ Ma thermocouple a cryogenic a zida zofufuzira mlengalenga
5. Zipangizo za Piezoelectric ndi Pyroelectric
- Dopant mu makhiristo osawoneka bwino (monga machitidwe a TeO₂-Li₂O):
✓ Masensa a pamwamba pa mafunde a acoustic (SAW) kuti azindikire mpweya
✓ Zipangizo zowunikira ma pyroelectric a IR zomwe zimayankha mwachangu (<10ms)
✓ Ma oscillator okhazikika pafupipafupi m'malo oyambira a 5G/6G
6. Mapulogalamu Omwe Akubwera
- Kupanga zinthu za Quantum:
✓ Chikhomo cha ma nanosheet a tellurene a 2D muzipangizo za spintronic
✓ Flux agent mu kukula kwa makristalo a superconductor okwera kwambiri
- Kutulutsa nthunzi ya mankhwala (CVD):
✓ Zophimba za TeO₂ zopyapyala za mawindo anzeru a electrochromic
✓ Zigawo za dielectric za Resistive RAM (ReRAM)
- Ukadaulo wa nyukiliya:
✓ Zosakaniza zoteteza ma neutron (magalasi a TeO₂-PbO-B₂O₃)
✓ Ma Scintillator matrices kuti azindikire neutrino
Ubwino Waukulu:
- Kutumiza kwa kuwala kwakukulu (0.35–5 µm)
- Kukhazikika kwa mankhwala m'malo okhala ndi asidi/oxidative
- Kugawanika kwa bandgap (3.7–4.2 eV) kwa ma optoelectronics okonzedwa
Chidziwitso: Imafunika kusamalidwa bwino chifukwa cha poizoni wochepa mu ufa. Nthawi zambiri imagwiritsidwa ntchito pogwiritsa ntchito mphamvu zake za amphoteric komanso zinthu ziwiri zoyeretsera (Te⁴+/Te⁶+).
Zinthu zambirizi zikupitirizabe kupangitsa kuti pakhale kupita patsogolo mu photonics, mphamvu zokhazikika, ndi ukadaulo wa quantum, ndi kafukufuku wopitilira wofufuza ntchito yake mu neuromorphic computing ndi terahertz waveguides.
