Taupānga waikura Cerium
1. Ko te Cerium Oxide, e kiia ana ko Ceria, e whakamahia nuitia ana i roto i te karaehe, te karaehe me te hanga whakakōkī.
2. I roto i te ahumahi karaihe, e kiia ana ko te tino pai rawa atu o nga kaihoko karaihe mo te whakakoi i te mata.
3. Ka whakamahia ano hoki hei whakakore i te karaehe ma te pupuri i te rino i roto i tona ahua ferrous.Ko te kaha o te karaihe Cerium-doped ki te aukati i te marama ultra violet ka whakamahia i roto i te hanga o nga karaihe rongoa me nga matapihi aerospace.
4. Ka whakamahia hoki hei aukati i te whakapouritanga o nga polymers i te ra me te pehi i te tae o te karaihe pouaka whakaata.
5. Ka whakamahia ki nga waahanga whatu hei whakapai ake i te mahi.Ka whakamahia hoki a Ceria ki te phosphors me te dopant ki te karaihe.
