| In conjunction with catalytic particles, such as cerium oxides, the filter has both a mechanical and chemical action. |
| By the usual convention, the element he obtained became known as cerium. |
| Misch metal, which contains a high proportion of cerium, is used to manufacture pyrophoric alloys. |
| For example, an alloy of calcium and cerium is used in flints in cigarette and other types of lighters. |
| The Sichuan ore has more lanthanum, less praseodymium and neodymium, and about the same amount of cerium as the Bayan Obo deposit. |
| Most of the other rare earths are fairly transparent to thermal neutrons with cross sections ranging from 0.7 barn for cerium to 170 for erbium. |
