Application

Cerium dioxide inoshandiswa sechinhu chinowedzera muindasitiri yegirazi uye sechinhu chekukuya chegirazi mahwendefa. Iyo yakawedzerwa kukuya girazi regirazi, optical lenses, uye cathode ray machubhu, uye ine mabasa akadai se decolorization, kujekesa, kunyura kweultraviolet uye electron rays mugirazi. Inoshandiswawo senge anti reflective agent yemaziso egirazi lenzi, cerium titanium yero inogadzirwa necerium kupa girazi reyero ruvara. Inoshandiswa sechinhu chinopinza pamuviri chepiezoelectric ceramics mune ceramic glazes uye indasitiri yemagetsi. Inoshandiswawo kugadzira macatalyst anoshanda zvakanyanya, incandescent zvivharo zvemarambi egasi, uye fluorescent skrini yeX-rays.
