What is zinc sulfide? Zinc sulfide,main dimensions: color, purity, packaging, storage method, sintering, and tablet pressing φ 10*6mm: φ 30 * 10mm white to light yellow 99.99% 1kg/bag, dry and stored from light and acid. The total content of aluminum, arsenic, cobalt, copper, iron, magnesium, manganese, lead, and tin impurities are less than ten ppm. Mainly used as important fluorescent material for pigments and fillers, used for battery screens, phosphors, fluorescent luminescent material, used for semiconductor components, piezoelectric, photoelectric, and thermoelectric devices, and can be used for ultraviolet radiation, anode ray, X-ray, it r it ray It, laser radiation detector material, laser window material.
Use of zinc sulfide As an important semiconductor of two or six compounds, zinc sulfide material has attracted great attention, not only because of its excellent physical properties, such as wide band gap, high refractive index, and high transmittance in the visible light range but also because of its huge potential for application in optical, electronic and optoelectronic devices. Zinc sulfide has an excellent fluorescence effect and electroluminescence function, nano-zinc sulfide has a unique photoelectric effect, and zinc sulfide is used in electricity; the fields of magnetism, optics, mechanics, and catalysis have shown many excellent properties, so the research of nanometer zinc sulfide has attracted more attention. In particular, Bhargava reported in 1994 that the surface passivation of nanometer zinc sulfide: manganese phosphor has not only an external quantum efficiency of up to 18% at high temperatures. Five orders of magnitude have shortened its fluorescence lifetime, and its luminescence performance has changed greatly. It opens up a new way to use zinc sulfide. Zinc sulfide can make white pigments, glass, luminous powder, rubber, plastic, paint, etc. It is undeniable that zinc sulfide has been used more and more widely at present. Due to the particularity of zinc sulfide, many research institutes will continue to explore the use of zinc sulfide.
Synthesis method of zinc sulfide The double decomposition method adds the zinc sulfate solution into the reactor, slowly adds the ammonium sulfide under the stirring to carry out the double decomposition reaction, generates the zinc sulfide and the ammonium sulfate, after filtering out the ammonium sulfate, and then evaporates, condenses, cools, crystallizes, and centrifuges to prepare the zinc sulfide finished product, adds the ammonia acetate to the zinc sulfate aqueous solution and maintains the pH value between 2 and 3. Then, while heating, the hydrogen sulfide is added to the residue and precipitation to the 2% acetic acid aqueous solution saturated with hydrogen sulfide; After shaking, filter and dry under the condition of isolating the air. To prepare the sample with good crystallinity, the residue can be heated to above 1100 ℃ in the hydrogen sulfide gas stream.
Price of zinc sulfide Zinc sulfide particle size and purity will affect the product's price, and the purchase volume can also affect the cost of zinc sulfide. A large amount of large amount will be lower. The price of zinc sulfide can be found on our company's official website.
