Ohun elo Cerium oxide
1. Cerium Oxide, tun npe ni Ceria, ti wa ni lilo pupọ ni gilasi, awọn ohun elo amọ ati iṣelọpọ ayase.
2. Ni ile-iṣẹ gilasi, o gba pe o jẹ oluranlowo didan gilasi ti o munadoko julọ fun didan opiti pipe.
3. O tun lo lati decolorize gilasi nipa titọju irin ni awọn oniwe-ferrous ipinle.Agbara ti gilasi Cerium-doped lati ṣe idiwọ ina violet ultra ni iṣelọpọ ti awọn gilasi iṣoogun ati awọn ferese afẹfẹ.
4. O tun lo lati ṣe idiwọ awọn polima lati ṣokunkun ni imọlẹ oorun ati lati dinku discoloration ti gilasi tẹlifisiọnu.
