Wide range of applications: (1) As a glass additive, it can absorb ultraviolet and infrared rays and has been widely used in automotive glass. It not only protects against UV rays, but also reduces the temperature inside the car, thus saving air conditioning power. Since 1997, Japan's auto glass has been added to yttrium oxide. In 1996, at least 2,000 tons of yttrium oxide was used for automotive glass, and about 1,000 tons in the United States. (2) At present, it is being applied to automobile exhaust gas purification catalysts, which can effectively prevent a large amount of automobile exhaust gas from being discharged into the air. The United States consumes one-third of the total consumption of rare earths in this respect. (3) cerium sulfide can replace lead, cadmium and other harmful to humans and the environment applied to the metallic pigment, colored plastics may also be used for paints, inks and paper industries. Currently leading is the French company Rhône Planck. (4) The CeiSAF laser system is a solid-state laser developed in the United States. It can be used to probe biological weapons by monitoring the concentration of tryptophan and can also be used in medicine.铈The application field is very extensive, and almost all rare earth applications contain bismuth. Such as polishing powder, hydrogen storage materials, thermoelectric materials, tantalum tungsten electrodes, ceramic capacitors, piezoelectric ceramics, silicon carbide abrasives, fuel cell raw materials, gasoline catalysts, some permanent magnet materials, various alloy steels and non-ferrous metals.
