Chemical element with the atomic number of 58.
1CATALYSTS - Petroleum cracking catalysts and auto catalysts use lanthanum and cerium.
2Its loparite concentrate holds light rare earths such as lanthanum and cerium.
3Few elements beyond cerium, the second lanthanide, were known in 1869.
4There are 17 rare earth metals including lutetium, cerium and europium.
5Likewise, cerium oxide might change its properties once mixed into soil.
6Nano-cerium oxide, meanwhile, accumulated around soybean roots and stunted plant growth.
7After cerium, he dotted his table with row after row of frustrating blanks.
8Objects are exposed by an X-ray beam from a cerium target.
9Separation is done by atomic weight, starting with cerium, the most abundant rare earth.
10How much thorium, not to speak of cerium, could they take at a maximum.
11Despite its name, cerium is not scarce and is as common as copper or zinc.
12The oxalate of cerium pill she swallowed with her tea is already disagreeing with her.
13On boiling, the cerium is precipitated as dioxide, which is filtered off, ignited, and weighed.
14Some light rare earths, like cerium and lanthanum, are very common, and therefore not as valuable.
15When water vapor was used, the catalyst would strip out its oxygen to re-form cerium dioxide.
16There is more cerium on Earth than copper, more neodymium and lanthanum than cobalt or nitrogen.
