Europium Sulfide powder is a black, air stable, inorganic compound powder with a cubic crystal system rock salt structure, a Curie temperature of 16.6 K and a melting point of 2250°C. It is ferromagnetic below its Curie temperature and paramagnetic above it. It is ferromagnetic below the Curie temperature and paramagnetic above it. It has a wide range of applications in magnetic recording, magneto-optical recording, spintronics, optics and catalysts.
Properties
Colour: Europium Sulfide is usually a black powder.
Density: Relatively high, approx. 5.75 g/cm³.
Melting point: Melting point up to 2250°C.
Solubility: insoluble in water, but soluble in acids.
Crystal structure: Europium Sulfide has a cubic crystal system rock salt structure.
Magnetic properties: Europium sulphide is an important magnetic material with ferromagnetism, the Curie temperature is 16.6K, it shows ferromagnetism when it is below the Curie temperature, and paramagnetism when it is higher than this temperature.
Optical properties: Europium Sulfide has photoluminescent properties, and can emit specific wavelengths of light under the excitation of light.
Stability: Stable in air, stable within a certain temperature range (below 500°C), oxidation will occur with continued heating.
APPLICATIONS
Magnetic recording field: due to its high magnetic moment and Curie temperature, it can be combined with other magnetic materials such as iron, cobalt, nickel, etc. and used in the manufacture of high-density magnetic recording media, such as magnetic tapes, magnetic discs, etc., which can improve the density and stability of magnetic recording.
Magneto-optical recording: Used as the magnetic layer of magneto-optical discs, in magneto-optical recording, laser beams and magnetic fields are used to write and read data, europium sulphide plays an important role in it.
Spintronics: It is a promising material for spintronic devices and has been used in the development of magnetic tunnel junctions, which have important applications in spintronic devices such as magnetic random access memory (MRAM).
Optical field: Its photoluminescent property makes europium sulphide powder can be applied in the field of optoelectronics, such as used in the manufacture of light-emitting diodes (LEDs), lasers and other optical devices.
Catalyst: As a potential catalyst, it has been studied for various chemical reactions, including hydrogenation, desulfurisation, oxidation and so on.
