New information on the use of ytterbium oxide Yb2O3 in 2021

 Overview of Ytterbium Oxide Yb2O3

Ytterbium oxide has the chemical formula Yb2O3. The molecular weight is 394.08. The pure product is colorless powder, light brown or yellow when it contains thulium oxide. Slightly hygroscopic, absorb carbon dioxide from the air. The proportion is 9.2. The melting point is 2,346°C. It is the weakest one in the yttrium group except for lutetium oxide. It is insoluble in water and cold acid, but soluble in hot dilute acid. Ytterbium oxide is used in the manufacture of permanent magnet materials, glass, ceramic colorants, laser materials, heat shielding coating materials, electronic materials, battery materials, biopharmaceuticals, electronics industry and chemical research applications showing superior performance. With the development of science and technology, large particles of ytterbium oxide are used in coating, sputtering, vacuum coating and other fields. For example, ytterbium oxide is coated on the surface of diamond, which increases the infrared transmittance of sewing by 12%, and has high resistance. Rain corrosion performance, the demand for large particles of ytterbium oxide is increasing. Because large particles of ytterbium oxide are used as thermal spraying powder, the amount of fine particles formed during thermal spraying will be reduced, and the fine particles formed by small particles during thermal spraying will adhere. The deposits deposited on the inner wall of the nozzle of the thermal spraying device fall off from the inner wall and are mixed into the thermal spray coating to reduce the accumulation resistance of the thermal spray coating, and directly prepare ytterbium oxide powder particles that meet the requirements of thermal spraying. Can improve coating density, accumulation resistance and abrasion resistance. The particle size of ytterbium oxide prepared by the traditional methods of ytterbium oxalate precipitation or ytterbium carbonate precipitation in the rare earth industry is generally in the range of 1 to 15μm. This ytterbium oxide is granulated as a thermal spray powder, and its coating is not as good as direct spray coating of large particles of ytterbium oxide. Layer performance.

Ytterbium is one of the elements that are difficult to separate and purify among all rare earth elements. Ytterbium oxide is a colorless solid, insoluble in water, soluble in hot dilute acid. Preparation method: Adjust the pH of the ytterbium salt solution to 2 with ammonia water, add saturated oxalic acid or ammonium oxalate solution, heat, filter, calcinate, or put the ytterbium hydroxide (or ytterbium carbonate) in the air at 900 Calcined at ℃. The application of high-purity ytterbium is currently still in the research and development or small-scale trial stage, mainly used for light, electricity, magnetism and some new functional materials, such as luminescent materials, optical glass, laser components, sensors, high temperature superconductors, medical imaging Agent, optical fiber, magnetic levitation, fuel cell, etc. Strengthening the research on the preparation process of high-purity Yb2O3 is of great significance for promoting its application research and giving full play to the advantages of my country's rare earth resources.

  Overview of Lithium Nitride  Li3N  Powder Lithium nitride is a metallic nitrogen compound with the molecular formula Li3N. It is the only stable alkali metal nitride. It is a purple or red crystalline solid, with a high melting point and a light green luster in reflected light and ruby color in transmitted light. Exposure to the air over a long period of time will eventually result in lithium carbonate. The chemistry of basic metal nitrides is extremely limited, and only lithium nitride is stable and easily prepared among binary compounds (sodium nitrite and potassium nitrite are prepared only under more extreme conditions). Lithium nitride belongs to the hexagonal crystal system. There are lithium and nitrogen layers composed of lithium and nitrogen atoms in lithium nitride crystal. The lithium atoms are arranged like carbon atoms in a graphite crystal, with nitrogen atoms at the center of a hexagon of lithium atoms. There is a lithium layer between the lithium and ni...

  Overview of Tungsten Disulfide Tungsten disulfide  as a potential battery material is also expected to benefit from more market replenishment. Tungsten disulfide is a layered material with remarkable surface effects, electron mobility, thermochemical stability and high electron density of states. It has been widely used for lithium and sodium storage. For example, nanocomposites as conductive additives or graphene composites as battery cathode materials can exhibit higher specific capacity and discharge efficiency, making up for the deficiencies of single-component WS2 or C as anode materials. The advent of sodium batteries is expected to alleviate the current shortage of lithium resources on the rapid development of the new energy industry, and will further stimulate the application of transition metal dichalcogenides such as tungsten disulfide WS2 in the field of power storage.  Lithium-ion batteries are a key raw material for developing energy devices and realizing t...
