The metal is used in alloys and other metallurgical applications and (because it oxidizes strongly and rapidly) in illumination, ignition , and signaling devices and in propellants. Misch metal, used in lighter flints, is 50% cerium.

铈及其化合物有很多用途，二氧化铈在光学工业中用于玻璃的精细拋光，在瓷器涂层中用作不透明剂，在玻璃制造业中用作脱色剂。

Ago a kind of misconception that the rare earth metals is very scarce in nature, in fact not the case, many of which elements such as lanthanum, cerium, praseodymium, neodymium and samarium in accordance with their distribution in nature is no less well-known people in some of the elements of industry, common There ore monazite, scandium yttrium stone, silicon and cerium stone, stone and brown curtains and other fluorocarbon calcium cerium ore.

以前有种错误概念，认为稀土金属在自然界很稀少，其实不然，其中很多元素如镧、铈、镨、钕和钐按其在自然界的分布不次于人们在工业上熟知的某些元素，常见的矿石有独居石、钪钇石、硅铈石、褐帘石和氟碳钙铈矿等。

Bastnaesite crystal about 12×20 mm in size collected from a pegmatitic aegirine augitebarite-bastnaesite vein of the Maoniuping rare earth deposit, Mianning County, Sichuan Province,has been analyzed for La, Ce, Pr and Nd by synchronous radiative X-ray fluorescence technics at the National BEPC Laboratory.

对采自四川省冕宁县牦牛坪稀土矿床中伟晶状霓辉石－重晶石－氟碳铈矿脉的一个氟碳铈矿晶体（约12×12mm）在BEPC国家实验室采用同步辐射X萤光技术分析了La、Ce、Pr和Nd。

Domestic products raw material, which bastnasite was used as active component for DeSOx additives, were selected to use for the first time, the bastnasite can replace industrial cerium nitrate, it may improve DeSOx activity and abrasive resistance, due to admission bastnasite, but also reduce cost of material of DeSOx additives.

本文采用三种方法拟在活性组分的选择、活性评价及作用机理等方面对DeSOx添加剂强度进行有益的探索；尤其首次选用国产原料——氟碳铈矿作为镁铝尖晶石DeSOx添加剂的活性载体，使得氟炭铈矿可以代替工业硝酸铈，它既可提高脱硫添加剂的活性和耐磨强度，还可以降低原料成本。

In order to obtain the optimal photoionzation scheme of cerium atom,odd-parity high-lying states were studied using this technique.
