Analytical reagent Zinc sulfide

What is zinc sulfide?

Zinc sulfide (molecular formula: ZnS) category, main dimensions, color, purity, packaging, storage method, sintering and pressing φ 10*6mm φ 30 * 10mm white to light yellow 99.99% 1kg/bag, protected from light and acid, dried and stored particles 1-3 mm; 3-5 mm crystal particles with a size of 1-40 mm are selected according to the requirements. The particle size is light yellow, translucent, 99.99%, and the chemical purity is above 99.999%. The total content of impurities in aluminum, arsenic, cobalt, copper, iron, magnesium, manganese, lead, and tin is less than ten ppm Product parameters: CAS number, density (g/cm3), evaporation temperature (), refractive index (550nm), transparency, waviness μ m) Evaporation source 1314-98-3 4.1 1100 2.3-2.4 0.35-14.5 E use of cold light film; Decorative film; Filter; High reflection film; Infrared film; Mainly used as pigments and fillers as necessary fluorescent materials. Used for battery screens, fluorescent powders, fluorescent luminescent materials, applied in semiconductor components, piezoelectric, optoelectronic, and thermoelectric devices, can be used for ultraviolet radiation, anode rays, X-ray, r-rays, laser radiation detector materials, laser window materials, ZnS thin film heterojunction optoelectronic devices, etc.

 

The Use of Zinc Sulfide

Promoting physical development: Zinc sulfide is a zinc supplement that can boost the human body's metabolic process and promote growth and development, playing a significant role. Improving anemia: Poor nutrition or poor appetite may lead to anemia symptoms. The use of zinc sulfide can improve anemia symptoms. Improving diet: When the body lacks zinc, it may cause a lack of appetite. By using it, it can effectively improve diet and increase body nutrition. In addition to the above effects, zinc supplementation can be used for the auxiliary treatment of colitis and oral cavity and can be used under the guidance of a doctor.

 

Synthesis method of zinc sulfide

The double decomposition method adds a zinc sulfate solution to a reactor and slowly adds ammonium sulfide under stirring for the double decomposition reaction to generate zinc sulfide and ammonium sulfate. After filtering out the ammonium sulfate, it is evaporated, concentrated, cooled, crystallized, and centrifuged to obtain a finished zinc sulfide product. The reaction formula follows: adding ammonium acetate to an aqueous zinc sulfate solution and maintaining a pH between 2 and 3. Then, while heating, hydrogen sulfide is introduced to precipitate. Add the deposit to a 2% acetic acid aqueous solution saturated with hydrogen sulfide; After shaking, filter and dry under isolated air conditions. To prepare a sample with good crystallinity, the residue can be heated to above 1100 in a 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 is on our company's official website.
