Cerium (Ⅳ) Hydroxide (Ce (OH))4CAS Nr .: 12014-56-1
Kev piav qhia ntawm cov khoom
Cerium hydroxide muaj cov khoom siv kho qhov muag zoo, cov khoom siv hluav taws xob thiab cov khoom siv catalytic, yog li nws tau siv dav hauv TFT-LCD (thin film transistor kua siv lead ua zaub), OLED (organic light emitting diode), LCOS (reflective kua siv lead ua zaub), automobile exhaust purifying. tus neeg sawv cev thiab IT kev lag luam.Nws kuj yog siv los npaj ceric ammonium nitrate, ceric sulfate, ceric ammonium sulfate thiab lwm yam tshuaj reagents.
WONAIXI lub tuam txhab (WNX) tau pib tsim cov cerium hydroxide nyob rau hauv 2011 thiab officially muab tso rau hauv loj ntau lawm nyob rau hauv 2012. Peb tsis tu ncua txhim kho cov txheej txheem ntau lawm thiaj li yuav muab cov neeg muas zaub nrog cov khoom zoo, thiab nrog rau cov txheej txheem siab heev thov rau cerium hydroxide. ntau lawm txheej txheem teb chaws invention patent.Peb tau tshaj tawm cov kev tshawb fawb thiab kev txhim kho kev ua tiav ntawm cov khoom no mus rau lub teb chaws science thiab technology department, thiab kev tshawb fawb ua tau zoo ntawm cov khoom no tau raug soj ntsuam raws li cov theem ua nyob rau hauv Suav teb.Tam sim no, WNX muaj peev xwm tsim tau txhua xyoo ntawm 2,500 tons ntawm cerium hydroxide.
