Zinc sulfide particles are an important inorganic compound material with various properties and wide applications.
Basic properties:
Appearance: Zinc sulfide particles are white to slightly yellow.
Crystal structure: There are two main crystal structures, the α variant and the β variant. The alpha variant is a colorless hexagonal crystal with a density of 3.98g/cm³. The β variant is a colorless cubic crystal with a density of 4.102g/cm³, and can be converted to the α type at 1020℃.
Solubility: Insoluble in water, but soluble in acid.
Melting point: High melting point, about 1700 ° C (α variant).
Preparation method:
Common method: It is usually obtained by the interaction of hydrogen sulfide and zinc salt solution.
Uniform precipitation method: This is a more special preparation method, the use of a chemical reaction to make the crystalline ions in the solution slowly and evenly released from the solution, by controlling the concentration of precipitating agent in the solution, to ensure that the precipitation in the solution is in a state of equilibrium, so as to uniformly precipitate zinc sulfide particles.
Applications:
Optical coating: Zinc sulfide has a high refractive index and good uniformity, which can be used for optical coating, such as manufacturing cold light film, decorative film, light filter, high reflection film, infrared film and so on.
Optical components: It is an important material for making infrared window, fairing and infrared optical components, which is suitable for thermal imaging systems.
Electronic field: It has application potential in semiconductor components, piezoelectricity, optoelectronics, thermoelectric devices, etc., such as substrate materials that can be used as phosphors for electroluminescent devices.
Pigment field: Due to its color and hiding power and other characteristics, it can be used in the manufacture of dyes, coatings, pigments and glass, which can provide good color and hiding effect for products.
Fluorescence characteristics: Adding trace amounts of copper, manganese, silver and so on to the crystal zinc sulfide as activators, after light can emit different colors of fluorescence, this characteristic makes zinc sulfide in phosphor, fluorescent luminescent materials and other aspects have important applications.
