Cerium metal is a rare-earths metal. Cerium metal is a solid and golden metal at normal pressure and temperature, it is a very hard metal. It easily oxidizes turning its surface in black. Cerium metal is the most frequent of the lanthanoids (rare-earths), most of it occurs mixed with the others of them. Often it is used as mischmetal, which contains a natural lanthanoid mixture and is cheaper than the separated lanthanoids. This typically consists of 50% cerium, 20% lanthanum and neodymium, 5% praseodymium and the other lanthanoids in fewer amounts as well as iron and other elements. Iron and cerium are the only elements, where by hard and fast friction sparks can be produced.
Amazing Cerium metal standard density cube 10x10x10mm, 99.99% pure. The sample weighs 6.6 grams (with a tolerance of ± 0.1gram), which is the theoretical density of the Cerium metal itself. This cube is amazing for any science classrooms, schools, universities and collectors. Pure Cerium metal cube for element collection.
The sample comes under argon sealed ampoule.
