Daim ntawv thov

Phosphors thiab Luminescent Cov Khoom Siv: Calcium tungstate yog dav siv los ua cov phosphor hauv cov roj fluorescence thiab lwm cov kev siv teeb pom kev zoo. Nws emits xiav lub teeb thaum zoo siab los ntawm ultraviolet (UV) hluav taws xob, ua rau nws haum rau siv nyob rau hauv ntau yam teeb pom kev zoo thev naus laus zis. Nws tseem siv nyob rau hauv scquillation detectors uas hloov hluav taws xob hluav taws xob rau hauv pom kev, ua rau nws muaj txiaj ntsig zoo hauv kev kho mob thiab kev kuaj kom muaj hluav taws xob.
Xoo hluav taws xob thiab gamma-duab detectors: Vim tias nws cov siab atomic naj npawb thiab ntom ntom, calcium tungstate tuaj yeem pom zoo X-Rays thiab Gamma Rays. Feem ntau nws siv nyob rau hauv kev kho mob cov kev ntsuas, xws li sau cov tshuab ntsuas thiab xoo hluav taws xob, txhawm rau hloov hluav taws xob ntsuas. Daim ntawv thov no yog qhov tseem ceeb los txhim kho qhov tseeb thiab kev nyab xeeb ntawm kev kuaj mob ntawm kev kuaj mob.
Ceramics Thiab Cov Iav: Calcium tungstate yog siv nyob rau hauv kev tsim cov ceramic thiab cov ntaub ntawv iav. Nws cov peev txheej txhim kho cov neeg kho tshuab muaj zog thiab thermal ruaj ntawm cov ntaub ntawv no, ua rau lawv haum rau cov ntawv thov kub siab. Calcium tungstate feem ntau ntxiv rau iav tsim qauv los txhim kho opacity thiab durability, tshwj xeeb tshaj yog cov khoom lag luam iav tshwj xeeb.
Twj huam: Calcium tungstate tuaj yeem siv ua catalyst lossis catalyst kev txhawb nqa hauv ntau yam tshuaj lom neeg, tshwj xeeb tshaj yog nyob hauv kev tsim cov tshuaj zoo thiab cov chaw muag tshuaj. Nws cov khoom tshwj xeeb tuaj yeem nce cov tshuaj tiv thaiv nce thiab xaiv tau, ua rau nws muaj txiaj ntsig zoo hauv cov txheej txheem kev muaj. Cov kws tshawb nrhiav tau tshawb txog nws lub peev xwm hauv cov ntawv thov Chemistry Green, qhov twg muaj txiaj ntsig thiab ib puag ncig cov txheej txheem yog qhov tseem ceeb.
