Neodymium Sulfide

Neodymium Sulfide Powder is a rare earth sulfide powder with grey appearance, chemical formula Nd₂S₃, density 5.46 g/cm³, produced by high temperature reaction of neodymium oxide and hydrogen sulphide, with certain chemical stability and potential applications in permanent magnetic materials, catalysts, optical materials and other fields.

Characteristic

Appearance: Neodymium Sulfide is usually grey powder.

Density: Neodymium Sulfide has a relatively high density of about 5.46 g/cm³, which makes neodymium sulfide powder need to pay attention to prevent piling up and extrusion during storage and transport.

Melting point: The melting point is high, about 1200℃, it has good high temperature resistance, and can still maintain a stable physical state under high temperature environment.

Solubility: Neodymium Sulfide is poorly soluble in water, but moderately soluble in acids, which means that chemical reactions may occur under some specific acidic conditions.

STABILITY: It is chemically stable at room temperature and pressure, but may react chemically under special conditions such as high temperatures, strong oxidising agents or strong acids. For example, the reaction with oxygen at high temperature will produce the corresponding oxide.

Oxidising and reducing properties: Neodymium element has certain oxidising and reducing properties in compounds, and neodymium sulphide powder may show similar chemical properties, and can be used as an oxidising or reducing agent in some chemical reactions.

Rare earth element properties: Neodymium Sulfide, as a kind of rare earth sulfide, has some typical chemical properties of rare earth elements, such as strong ability to form complexes or compounds with other elements, which can be used to prepare various rare earth compounds.

Magnetic properties: as neodymium is a magnetic element, neodymium sulphide powder may have certain magnetic properties, but the specific magnetic strength and magnetic properties will be affected by the preparation method of the powder, particle size distribution and other factors.

Optical properties: Neodymium Sulfide may have certain properties in optics, such as the ability to absorb or reflect light of specific wavelengths, which makes it potentially useful in the field of optical materials.

Applications

In the field of permanent magnetic materials: it can be used as an additive or auxiliary material for the production of permanent magnetic materials such as NdFeB, which can improve the performance of permanent magnetic materials, such as increasing the magnetic energy product and improving the coercivity. These permanent magnetic materials are widely used in motors, generators, loudspeakers, computer hard discs and other devices.

Catalyst field: It can be used as a catalyst in some chemical reactions, such as in hydrogenation, dehydrogenation, oxidation, etc. Neodymium sulphide powder can reduce the activation energy of the reaction and improve the reaction rate and selectivity.

Optical materials: due to its unique optical properties, it can be used in the preparation of optical glass, optical fibres, lasers and other optical materials, and can improve the performance of optical materials, such as improving the refractive index, increasing the optical transmittance and so on.

Electronic device field: it can be used as dopant of semiconductor materials to improve the electrical properties of semiconductors, and has potential applications in the manufacture of electronic devices such as smart phones, computers, solar cells and other products.

Chemical synthesis field: It is used in the preparation of other rare earth sulfides or compounds containing neodymium, and is an important raw material for chemical synthesis.

Ceramic materials field: added to ceramic materials, it can improve the performance of ceramics, such as increasing the hardness, wear resistance and high temperature resistance of ceramics.
