CERIUM
The chemical symbol of cerium is CE and the atomic number is 58. Cerium is a soft, malleable silver white metal that discolors when exposed to air and is soft enough to be cut with a knife. Cerium is the most abundant rare earth. Its chemical characteristic is that it has two valence states, namely + 3 CE state and + 4 CE state. Cerium state is the only stable non trivalent rare earth ion in aqueous solution. Therefore, it is a strong acid and strong oxidant. Cerium state is very similar to other trivalent rare earth.
CESIUM OXIDE
Cesium oxide is a kind of inorganic compound, which is composed of cesium and oxygen. It belongs to oxide. Its chemical formula is CS Е o. The known binary cesium oxides are CS ₁₁ o ₃, CS ₄ o, CS ₇ O and CS ₇ o. They are brightly colored. The appearance of cesium oxide CS ξ o is orange yellow hexagonal crystal.
Cerium Dioxide
Light yellow or yellow brown powder. The density is 7.13g/cm³. Melting point 2397 °C. Insoluble in water and alkali, slightly soluble in acid. At 2000 °C and 15MPa, cerium oxide can be obtained by hydrogen reduction of cerium oxide. When the temperature is free between 2000 °C and the pressure is free at 5MPa, cerium oxide is yellowish red and pink. Its performance is used as polishing material, catalyst, catalyst carrier (Assistant), ultraviolet absorber, fuel cell electrolyte, automobile exhaust absorber, electronic ceramics Wait.
Cobalt
Steel gray metal powder, easily oxidized in the air at room temperature. It is widely used in aviation, aerospace, electrical appliances, machinery manufacturing, chemical and ceramic industries. Cobalt-based alloys or cobalt-containing alloy steels are used as blades, impellers, ducts, jet engines, rocket engines, missile components and various high-load heat-resistant components in chemical equipment and important metal materials in the atomic energy industry. As a binder in powder metallurgy, cobalt can ensure the toughness of cemented carbide. Magnetic alloy is an indispensable material in modern electronics and electromechanical industries, used to make various components of sound, light, electricity and magnetism. Cobalt is also an important component of permanent magnetic alloys. In the chemical industry, in addition to high-alloy and anti-corrosion alloys, cobalt is also used in colored glass, pigments, enamels, catalysts, and desiccants.
Cobalt Oxide
Cobalt oxide is also called cobalt oxide and cobalt monoxide, chemical formula CoO, light grayish green crystalline powder. The relative density is 6.45 and the melting point is 1935°C. Insoluble in water and alcohol, soluble in dilute acid to become a light red solution, and blue when soluble in hot concentrated sodium hydroxide. It is insoluble in ammonia, but when oxygen is present, it can react with ammonia to form a complex and dissolve. Roasting in the air produces black cobalt tetroxide. It can be reduced to metallic cobalt by carbon powder, hydrogen or carbon monoxide. Cobalt oxide can be obtained by oxidizing metal cobalt powder in oxygen or air, or heating and decomposing cobalt nitrate, cobalt carbonate or cobalt hydroxide in a vacuum or in an inert atmosphere.
DYSPROSIUM
