Cerium oxide Application
1. Cerium Oxide, inonziwo Ceria, inoshandiswa zvakanyanya mugirazi, ceramics uye catalyst kugadzira.
2. Muindasitiri yegirazi, inoonekwa seyakanyanya kushanda girazi yekupuruzira mumiriri weiyo chaiyo optical polishing.
3. Inoshandiswawo kuita decolorize girazi nekuchengeta simbi iri muferrous state.Kugona kwegirazi reCerium-doped kuvharisa mwenje we ultra violet kunoshandiswa mukugadzira girazi rekurapa uye mahwindo emuchadenga.
4. Inoshandiswawo kudzivirira mapolima kuti asasviba muchiedza chezuva uye kudzvanyirira kushanduka kwegirazi reterevhizheni.
5. Inoshandiswa kune optical components kuvandudza kushanda.Kuchena kwepamusoro Ceria inoshandiswawo muphosphors uye dopant kune crystal.
