Kodi Tantalum Oxides ndi Tantalum Pentoxides zimagwiritsidwa ntchito bwanji?
Madera ofunikira kwambiri
1. Zipangizo zamagetsi zogwirira ntchito
1. Chosefera cha Surface Acoustic Wave (SAW) Substrate:
- Zipangizo zazikulu zopangira makhiristo amodzi a lithiamu tantalate (LiTaO₃), omwe amagwiritsidwa ntchito popanga zosefera zama radio pafupipafupi pazida zolumikizirana zam'manja.
- Mapulogalamu a terminal: mafoni/mapiritsi (chithandizo cha gulu la 5G), ma module a GPS, mita zanzeru za IoT
- Ubwino wa magwiridwe antchito: kukhazikika kwa pafupipafupi ± 0.5ppm (-40℃ mpaka +85℃)
2. Zoyambira za Semiconductor:
- Zinthu zopangira za Tantalum carbide (TaC): zopangira zida zolimba kwambiri (kulimba pang'ono ≥ 2200 HV)
- Cholinga chothira madzi: DRAM capacitor dielectric layer deposition (dielectric constant εr = 25-30)
2. Ukadaulo wa Maso
1. Dongosolo la kuwala lapamwamba kwambiri:
- Chowonjezera chizindikiro cha Refractive: Wonjezerani chizindikiro cha refractive cha galasi la kuwala kufika pa nd=1.75-2.20 (400-700nm)
- Chophimba chochepa cha kuyamwa: Kukonzekera filimu yotsutsana ndi kuwunikira (kuchuluka kwa kutha kwa mpweya k<0.001@550nm)
2. Ntchito zapadera za ulusi:
- Fiber Bragg Grating dopants: Sinthani kutentha kufika pa 15pm/°C
- Zigawo za kuwala za infrared: Kutumiza kwa magetsi mu gulu la mid-infrared la 3-5μm > 92%
3. Kukonza ndi Kusintha kwa Mafakitale
1. Kukonza Mankhwala:
- Chothandizira cha Olefin epoxidation: kuchuluka kwa kusintha > 95% (chotengera chokhazikika cha bedi)
- Photocatalyst yopangira haidrojeni kuchokera m'madzi (yopangidwa ndi CdS)
2. Kusintha kwa zinthu:
- Zowonjezera za aloyi zosagwira dzimbiri: Zimathandizira kukana okosijeni kwa aloyi okhala ndi nickel pa 1100°C
- Gawo lolimbitsa la Ceramic: Kulimba kwa kusweka kwa zinthu zopangidwa ndi alumina kwawonjezeka ndi 40%

Chitetezo ndi Kutsatira Malamulo
Gulu la Mayendedwe: OSATI OPSA (Nambala ya UN sikugwira ntchito)
Zofunikira pakusungira: malo ouma kutentha kwa chipinda, pewani kukhudzana ndi asidi wamphamvu
Chitsimikizo cha chilengedwe:
- Kutsatira malangizo a RoHS 3.0 (2015/863/EU)
- Zinthu zomwe sizinatchulidwe pansi pa REACH SVHC
- Kutsatira Ndondomeko ya Migodi Yotsutsana (CMRT 6.0)
Kuwongolera Ubwino
1. Miyezo ya Giredi:
- Giredi yowunikira: ISO 10110-7 giredi yozungulira A
- Kalasi yamagetsi: SEMI C8.1 kulamulira kuipitsidwa kwachitsulo
2. Chitsimikizo cha kuyesa:
- Perekani lipoti la kusanthula kwa XRF kwa gulu lililonse
- Kuzindikira malo a BET pamwamba (0.5-10m²/g yosinthika)
- Kuwunika kwa Radionuclide (U/Th < 1 ppb)

Milandu yodziwika bwino yogwiritsira ntchito
- Wopanga zosefera za siteshoni ya 5G amagwiritsa ntchito Ta₂O₅ yamagetsi, zomwe zimachepetsa kutayika kwa insertion kufika pa 1.2dB (3.5GHz band)
- High-end camera lens manufacturers use optical-grade products to achieve a refractive index of nd=2.15@587.6nm
Zinthu zofunika kuziganizira
• Kusamalira ufa wa nano kuyenera kutsatira miyezo ya ISO 13137 yoteteza kupuma
• Ma crucible a Corundum amalimbikitsidwa kuti agwiritsidwe ntchito pochotsa kutentha kwambiri
• Zophimba za kuwala ziyenera kulamulira kuchuluka kwa malo osungiramo zinthu kufika pa 0.5nm/s

Kufotokozera kumeneku kumachokera ku makhalidwe onse a tantalum pentoxide. Magawo enieniwo amadalira COA (lipoti lowunikira khalidwe).
Mayankho aukadaulo opangidwa mwamakonda angaperekedwe pamitundu yapadera (nanopowders/sputtering target/single crystal substrates).
