Daim ntawv thov

ammonium cerium nitrate (CAN), yog cov khoom tseem ceeb rau kev ua Chrome etchant uas yog ib qho tseem ceeb heev micro electronic circuit corroding cov ntaub ntawv rau LCD; CAN kuj tseem siv rau hauv cov iav tshwj xeeb thiab catalyst. Hauv cov hlau, Cerium degasifies thiab tuaj yeem pab txo cov Sulfides thiab Oxides, thiab nws yog cov nag lossis daus hardening tus neeg sawv cev hauv stainless hlau. Cerium alloys yog siv rau hauv cov hlau nplaum ruaj khov, thiab hauv tungsten electrodes rau roj tungsten arc vuam. Nws kuj yog siv nyob rau hauv carbon-arc teeb pom kev zoo, tshwj xeeb tshaj yog nyob rau hauv lub motion picture industry.
