| ʻO ka Tellurium dioxide (hui) kahi ʻano oxide o ka tellurium. ʻO kona ʻano kemika ka hui ʻana o TeO2. No ka moʻo kristal huinahā kona kristal. Kaumaha molekala: 159.61; pauka keʻokeʻo a i ʻole nā poloka. |
E pili ana i ka Tellurium Dioxide
ʻO ka hopena nui o ka puhi ʻana o ka tellurium i ka lewa, ʻo ia ka tellurium dioxide. ʻAʻole hiki i ka tellurium dioxide ke hoʻonā i ka wai akā hiki ke hoʻonā piha i ka waikawa sulfuric i hoʻohuihui ʻia. Hōʻike ka Tellurium dioxide i ka paʻa ʻole me ka waikawa ikaika a me ka oxidant ikaika. ʻOiai he mea amphoteric ka tellurium dioxide, hiki iā ia ke pane i ka waikawa a i ʻole ka alkaline i loko o ka hopena.
ʻOiai he kiʻekiʻe loa ka hiki o ka tellurium dioxide ke hoʻoulu i ke ʻano ʻino a he mea ʻawahia, ke komo i loko o ke kino, hiki iā ia ke hoʻopuka i kahi ʻala (ʻala tellurium) e like me ke ʻala o ke kālika i ka hanu. ʻO kēia ʻano mea ka dimethyl tellurium i hana ʻia e ka metabolism o ka tellurium dioxide.

He aha ka mea e hoʻohana ʻia ai ka Tellurium Dioxide Powder?
Tellurium Dioxide (TeO₂)He hui inorganic hana kiʻekiʻe ka pauka i kaulana no kona mau waiwai optoelectronic, thermal, a me ke kūkulu kūikawā. ʻO kona versatility e uhi ana i nā ʻāpana ʻenehana holomua, ka noiʻi ʻepekema, a me ka hana ʻoihana, me nā noi koʻikoʻi e like me:
1. Nā Mea Acousto-Optic
- Hana ma ke ʻano he ʻāpana mua i loko o nā kristal hoʻokahi paratellurite (α-TeO₂), e hiki ai ke hoʻololi wikiwiki i ka mālamalama no:
✓ Ke hoʻokele kukuna laser a me ka hoʻololi pinepine ʻana
✓ Nā ʻōnaehana kamaʻilio optical (nā kānana DWDM, nā kuapo Q)
✓ Ke kiʻi ʻana o Ultrasonic a me ka holography manawa maoli
- Hōʻike i ka helu kūpono acousto-optic (M₂) kūikawā no nā hāmeʻa hoʻonā kiʻekiʻe e hana ana i nā spectra ʻike ʻia e ka mid-IR.
2. Nā ʻōnaehana aniani holomua
- Hana ma ke ʻano he mea hana aniani kūlana i nā aniani maka kūikawā:
✓ Nā aniani tellurite haʻahaʻa-phonon-energy no nā mea hoʻonui fiber (Er³+/Pr³+-doped) i nā kamaʻilio kelepona
✓ Nā aniani kiʻekiʻe-refractive-index no nā aniani infrared a me nā optics ʻike pō
✓ Aniani i ʻike ʻia i ka radiation no nā mea dosimetry a me scintillation
3. ʻenehana Semiconductor
- Mea hoʻomaka koʻikoʻi no nā semiconductors hui II-VI:
✓ Ka ulu ʻana o ke aniani CdTe/CdZnTe no nā mea ʻike X-ray/γ-ray a me nā cell solar
✓ Hana ʻana i nā kiko quantum ma muli o HgTe no nā mea ʻike kiʻi IR hiki ke hoʻololi ʻia
✓ Hoʻohui ʻia i loko o ka noiʻi insulator topological (e laʻa, Bi₂Te₃/TeO₂ heterostructures)
4. Nā ʻōnaehana hoʻololi ikehu
- Hoʻāla i nā polokalamu thermoelectric kiʻekiʻe-ka pono:
✓ Nā hui Bismuth telluride (Bi₂Te₃) no nā mea hoʻoluʻu Peltier i loko o ka microelectronics
✓ Nā modula hoʻōla wela ʻōpala (ZT >1.2 ma 300-500K)
✓ Nā thermocouples cryogenic no nā lako ʻimi lewa
5. Nā Mea Hana Piezoelectric & Pyroelectric
- Dopant i loko o nā kristal optical non-linear (e laʻa, nā ʻōnaehana TeO₂-Li₂O):
✓ Nā mea ʻike nalu leo (SAW) no ka ʻike ʻana i ke kinoea
✓ Nā mea ʻike pyroelectric IR me ka pane wikiwiki (<10ms)
✓ Nā oscillator i hoʻopaʻa ʻia i ka alapine (frequency-stabilized) ma nā kikowaena kumu 5G/6G
6. Nā Polokalamu e kū mai ana
- Hoʻohuihui mea Quantum:
✓ Kumu hoʻohālike no nā nanosheets tellurene 2D i nā mea spintronic
✓ Mea hoʻoheheʻe i ka ulu ʻana o ke kristal superconductor Tc kiʻekiʻe
- Hoʻokomo mahu kemika (CVD):
✓ Nā uhi ʻili lahilahi TeO₂ no nā puka makani akamai electrochromic
✓ Nā papa dielectric Resistive RAM (ReRAM)
- ʻenehana nukelea:
✓ Nā hui pale neutron (nā aniani TeO₂-PbO-B₂O₃)
✓ Nā matrices scintillator no ka ʻike ʻana i ka neutrino
Nā Pōmaikaʻi Koʻikoʻi:
- Ka laulā hoʻoili ʻike ākea (0.35–5 µm)
- Paʻa kemika kiʻekiʻe i nā wahi waikawa/oxidative
- ʻO ka bandgap hiki ke hoʻololi ʻia (3.7–4.2 eV) no nā optoelectronics i hana ʻia
Nānā: Pono ka lawelawe ʻana i kāohi ʻia ma muli o ka ʻawahia iki i ke ʻano pauka. Hoʻohana pinepine nā noi i kona ʻano amphoteric a me nā kūlana oxidation pālua (Te⁴+/Te⁶+).
Ke hoʻomau nei kēia mea multifunctional i ka hiki ʻana i nā holomua i ka photonics, ka ikehu hoʻomau, a me nā ʻenehana quantum, me ka noiʻi e hoʻomau nei e ʻimi nei i kāna kuleana i ka helu neuromorphic a me nā waveguides terahertz.
