Expand the knowledge about cerium;

Cerium is a rare earth metal. Cerium is a silver-gray active metal, belonging to rare earth elements, and the periodic system is a subfamily bedding element of11. The symbol of the element is Ce, and the powder is easy to spontaneously ignite in air, but soluble in acid and reducing agent. The name of cerium comes from the English name of the asteroid Ceres. The content of cerium in the earth's crust is about 0.0046%, which is the most abundant among rare earth elements. Atomic number 58, atomic weight 140.5438+0 15.

The expansion of the application scope of cerium;

In the field of magnetic materials, people have been looking for breakthroughs and hope to develop products with higher cost performance. The research on the preparation method of Ce-Fe-B alloy strip has never stopped. It is learned from relevant people in the rare earth industry that cerium, iron and boron technologies are relatively more mature this year. This undoubtedly opens up a new application way for the application of cerium.

Pure cerium is not easy to spontaneous combustion, but it is easy to spontaneous combustion when it is slightly oxidized or alloyed with iron. When heated, it burns in the air to generate cerium dioxide. Cerium is the most abundant metallic element among rare earth elements. The common flint is made of it. Cerium can also be used as an alloy additive, as well as in the production of cerium salts and other industries, such as medicine, tanning, glass and textiles. Cerium can be used as catalyst, arc electrode and special glass. Cerium alloy is resistant to high temperature and can be used to make jet propeller parts.
