1. Ko te Cerium Oxide, e kiia ana ko Ceria, e whakamahia whānuitia ana i roto i te hanga karāhe, uku me te whakakorikori.
2.I roto i te umanga karāhe, e kiia ana koinei te mea whakakanapa karāhe tino whai hua mō te whakakanapa whatu tino tika.
3. Ka whakamahia hoki hei tango tae i te karāhe mā te pupuri i te rino i roto i tōna āhua rino. Ko te kaha o te karāhe kua pania ki te Cerium ki te aukati i te mārama ultra violet ka whakamahia i roto i te hanga i ngā karāhe hauora me ngā matapihi rererangi.
4. Ka whakamahia hoki hei ārai i te whakapouri o ngā pūmua i te rā, hei pehi hoki i te taekore o te karāhe pouaka whakaata.
5. Ka whakamahia ki ngā wāhanga whatu hei whakapai ake i te mahi. Ka whakamahia hoki ngā Ceria tino parakore ki roto i ngā phosphor me ngā tāpiringa ki te tioata.
