Cerium oxide Application
1. Cerium Oxide, yomwe imatchedwanso Ceria, imagwiritsidwa ntchito kwambiri pagalasi, zoumba ndi kupanga chothandizira.
2. M'makampani agalasi, amaonedwa kuti ndiwothandiza kwambiri popukuta magalasi kuti azitha kupukuta bwino.
3. Amagwiritsidwanso ntchito kuyeretsa galasi posunga chitsulo mu ferrous state.Kutha kwa magalasi a Cerium-doped kutsekereza kuwala kwa ultra violet kumagwiritsidwa ntchito popanga zida zamagalasi azachipatala ndi mawindo apamlengalenga.
4. Amagwiritsidwanso ntchito kuteteza ma polima kuti asadere ndi kuwala kwa dzuwa komanso kupondereza magalasi a kanema wawayilesi kuti asasinthe.
5. Amagwiritsidwa ntchito pazigawo za kuwala kuti apititse patsogolo ntchito.Kuyera kwakukulu Ceria amagwiritsidwanso ntchito mu phosphors ndi dopant to crystal.
