properties | erbium oxide (erbium trioxide) is pink powder, which easily absorbs moisture and carbon dioxide. It turns into hexagonal crystal when heated to 300C. Unhappy. Slightly soluble in inorganic acid, insoluble in water. Relative density 8.64. It's irritating. |
Structure | Erbium trioxide has only one stable compound, which is a powder with two structures of body-centered cubic and monoclinic. |
application | erbium oxide can be used as a control material for nuclear reactors, an additive material for yttrium iron garnet, and a rose red colorant for glass; it is also used to make infrared absorption And special luminescent glass. |
toxicity | see cerium oxide products. |
Use | Used as an additive for magnetic materials and phosphors, and a raw material for special luminescent glass Mainly used as yttrium iron garnet doping agent and nuclear reactor control material. It can also be used to make special luminous glass and infrared absorbing glass. It is also used as a glass colorant to give the glass a rose red color. scientific research reagents, biochemical research used as additives for magnetic materials and phosphors, coloring raw materials for special luminescent glass, and reactor control materials. |
Production method | Burning method Erbium nitrate or erbium sulfate solution is precipitated with hydroxide to generate erbium hydroxide or its alkaline salt, which is separated and burned to produce erbium oxide. Its 2Er(OH)3 → Er2O3 3H2O |
