The main application of dysprosium oxide Dy2O3 products

Overview of dysprosium oxide Dy2O3

Dysprosium oxide Dy2O3 is a white crystalline powder with strong magnetism, and its magnetic force is 12.8 times that of ferric oxide. The relative density is 7.81 (27/4°C), and the melting point is 2391°C. It is insoluble in water, but soluble in acid to generate the corresponding acid dysprosium salt solution. It is easy to absorb carbon dioxide from the air and become dysprosium basic carbonate. It is obtained by burning dysprosium hydroxide, dysprosium carbonate or dysprosium nitrate at 900°C. Used in industrial sectors such as electronics, radio and atomic energy.

Application of Dysprosium Oxide Dy2O3

Dysprosium oxide is a white powder, slightly hygroscopic, and can absorb moisture and carbon dioxide in the air. Dysprosium oxide is an important rare earth material with a wide range of uses. In addition to the nuclear reactor control rod used in the atomic energy industry, it can also be used for metal halide lamps, magneto-optical memory materials, glass, neodymium iron boron permanent magnet additives, etc. Dysprosium oxide is an important raw material for the preparation of metal dysprosium. Dysprosium is a strategic metal with extremely important uses. It is an important part of infrared generators and laser materials. Examples of its applications are as follows:

1) Preparation of a graphene-coated nanometer dysprosium oxide. The method includes the following steps: 1. Prepare dysprosium oxide nanoparticles by pyrolysis; 2. Prepare dysprosium oxide nanopillars by hydrothermal method; 3. Prepare graphene oxide solution Four, adding dysprosium oxide nanoparticles and dysprosium oxide nanocolumns to the graphene oxide solution, stirring and filtering to obtain a filter residue, the filter residue is subjected to heat treatment to obtain graphene-coated nanometer dysprosium oxide. In addition, the present invention also provides an application of the graphene-coated nanometer dysprosium oxide prepared by the above-mentioned method in the preparation of binary doped magnesium diboride superconducting bulk materials. The process method of the present invention is simple, and graphene with high surface area is used as the coating, which is beneficial for dysprosium oxide nanoparticles and dysprosium oxide nanopillars to be uniformly dispersed on the graphene without agglomeration, and is beneficial to improve the binary doping The critical current density Jc performance of magnesium boride superconducting bulk materials in low and high fields.

2) Prepare a kind of dysprosium oxide and scandium oxide as an additive to produce high-performance silicon nitride (Si3N4) ceramics by pressureless sintering. Its composition and mass percentage content are: dysprosium oxide 3%~7%, scandium oxide 5%~8%, silicon nitride 85%~92%. The purpose is to overcome the shortcomings of the prior art and provide a method for producing high-performance silicon nitride ceramics by pressureless sintering with dysprosium oxide and scandium oxide as an additive, which can be widely used in the preparation of parts in the fields of chemical industry, machinery, metallurgy, aerospace, etc.

3) Prepare molybdenum-based dysprosium oxide material, under the protection of inert gas, dry dysprosium oxide powder with a purity of more than 99% and dried molybdenum powder with a purity of more than 99.5%, according to the mass percentage Mo? (3~55)wt%Dy2O3 After weighing and mixing, add process control agent and make the final mass concentration not exceed 2.5wt% to obtain mixed powder; put the above mixed powder at ball-to-battery ratio 0.8~35:1, filling coefficient 0.05~0.85, ball mill speed 80 Under the condition of ~650rpm, follow the ball milling method for 45~60min—stop 4~12min for 2~100h; then, the mixed powder after ball milling is cold isostatically pressed under the condition of 80~550MPa for 0.05~4h to form a green body ; Then the green body is sintered under the protection of inert gas at 1200~1900℃ for 2~110h to obtain molybdenum-based dysprosium oxide core block, which is an excellent neutron absorber core block material for ash control rod.
