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. Cerium compounds (in which it has valence 3 or 4)are used in the mantles of lanterns, in the ceramic, photographic, and textile industries, and in analytical chemistry.

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(代替铁丹)，在瓷器涂层中用作不透明剂，在玻璃制造业中用作脱色剂。硝酸铈用来制造汽灯纱罩，其它铈盐用于陶瓷、摄影和纺织工业，金属铈是渗碳弧光灯的配料之一。

用打火石生火

||1: The idea is spreading. In Britain, where childcare is costly-the average family with two earners spends 27% of after-tax income on it-day camps are popular. ||2: Super Camps, a national operator, charges ￡38 ($60) a day at most. ||3: A smaller rival, Camp Energy in Oxfordshire, charges ￡33. ||4: One of the founders of Mumsnet, a parenting website, calls such fees "eye-wateringly expensive". ||5: Yet to many, they are a bargain. ||6: The minimum hourly wage for childminders is ￡6.08 and they will not teach you how to make fire with flints .

||1: 这个主意正在传播。在英国，由于儿童托管的昂贵费用占到拥有两个收入者的普通家庭税后的27% ，因此日间夏令营很受欢迎。 ||2:国营的超级营地最多一天收费38英镑（合60美元）。||3: 一个规模较小的竞争对手—牛津郡的Camp Energy收费33英镑。 ||4:一个育儿网站Mumsnet网的创始人之一称这种费用"十分昂贵"。||5:然而对许多人来说,他们很便宜。||6:保育员每小时最低工资是6.08欧元，同时他们也不会告诉你如何用燧石生火。

For example , to improve the grinding of flints , which were used in the rising pottery industry .

例如，布林德雷努力的改良燧石的碾磨过程，燧石是新兴的陶瓷工业有用的材料。
