Some, such as a glass and oxides, can have a lot to absorb slow neutrons to the nature of radiation, in which cerium oxide added is a better one, such as γ-ray irradiation by the radiation of glass, the visible light The transmission rate has dropped less. Cerium oxide in the glass and generally 0.1-1.6 after anti-105-107γ ray radiation, radiation with a glass of this nature can be observed as nuclear facilities and other porous materials and optical instruments. Solar cells can produce glass and so on. In addition, CeO2 glass can also be used as a clarifying agent, but also make glass welding goggles, sunglasses, glass, light colored glass and colored glass, a qualitative change. CeO2 in the glass industry is an excellent additive material.
