Ceo22 is used as optical materials , polishing agents , ultraviolet absorption materials , the cleaning catalyst of car ' s waste gases , chemical decolorant of glass , radiation - resisting glass permanent magnet , electronic ceramics etc . if it is processed into nanoparticles , it will exhibit some novel properties led to varied applications . for example , ceo22 nanocrystal is a better promoter of cytochrome c and the stabilizer of zro22 ceramics . because of its high index of refraction and good stability , it is used to produce reduced reflection film Ceo _ 2是一种廉价而用途极广的材料，如用于发光材料、抛光剂、紫外吸收材料、汽车尾气净化催化剂、玻璃的化学退色剂、耐辐射玻璃、永磁体、电子陶瓷等，其纳米化后将出现一些新的性质及应用，如ceoz纳米晶是细胞色素c的良好的催进剂，还用作zro :陶瓷的稳定剂，由于ceo :折射率高，稳定性好，常用于制备减反射膜等。
