Taupānga
Ko te Cerium chloride heptahydrate, i roto i te ahua o te whakahiato karaihe, te whakahiato kowhai marama ranei, te mea nui mo te whakakorikori, karaihe, ūkuikui me nga paura whakakoi. 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. Ka whakamahia hoki hei aukati i nga polymer kia pouri i te ra me te pehi i te tae o te karaihe pouaka whakaata. Ka whakamahia ki nga waahanga whatu hei whakapai ake i te mahi. Ko te Cerium chloride he used i roto i nga ahumahi pērā i te hinu whakakōkī, automotive whakakōkī paura, pūhui takawaenga, me ētahi atu Kei te whakamahia hoki te reira mo te hanga cerium whakarewa, me ētahi atu Kei te whakamahia Cerium pūhaumāota i roto i ahumahi pērā i takawaenga ho'oraa, cerium tote raw rauemi, tāpiritanga koranu mārō, me te matū. reagents
