Structure of Zinc sulfide (CAS NO.1314-98-3):
IUPAC Name: Sulfanylidenezinc
Canonical SMILES: S=[Zn]
InChI: InChI=1S/S.Zn
InChIKey: WGPCGCOKHWGKJJ-UHFFFAOYSA-N
Product Category of Zinc sulfide (CAS NO.1314-98-3): Inorganics;Chemical Synthesis;Catalysis and Inorganic Chemistry;Metal and Ceramic Science;Electronic Chemicals;Micro/Nanoelectronics
Uses
Zinc sulfide (CAS NO.1314-98-3) was used by Ernest Rutherford and others in the early years of nuclear physics as a scintillation detector, and is also used as an infrared optical material, transmitting from visible wavelengths to over 12 micrometres. It can be used planar as an optical window or shaped into a lens, and is used as phosphor in many applications, from cathode ray tubes through x-ray screens to glow in the dark products.
Production
Zinc sulfide (CAS NO.1314-98-3) is easily produced by mixing an amount of zinc and sulfur and then igniting it: Zn2+ + S2 → ZnS .This has formed the basis of a gravimetric analysis for zinc.

Specification
Zinc sulfide , its cas register number is 1314-98-3. It also can be called C.I. Pigment White 7 ; Cleartran ; and Zinc monosulfide . It is typically encountered in the more stable cubic form, known also as zinc blende or sphalerite. The first time its phosphorescence was observed by the French chemist Théodore Sidot in 1866. It is hazardous, so the first aid measures and others should be known. Such as: When on the skin: first, should flush skin with plenty of water immediately for at least 15 minutes while removing contaminated clothing. Secondly, get medical aid. Or in the eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Then get medical aid soon. While, it's inhaled: Remove from exposure and move to fresh air immediately. Give artificial respiration while not breathing. When breathing is difficult, give oxygen. And as soon as to get medical aid. Then you have the ingesting of the product: Wash mouth out with water, and get medical aid immediately. Notes to physician: Treat supportively and symptomatically.
In addition, Zinc sulfide (CAS NO.1314-98-3) could be stable under normal temperatures and pressures. It is not compatible with strong oxidizing agents, and you must not take it with incompatible materials. And also prevent it to broken down into hazardous decomposition products: Oxides of sulfur, hydrogen sulfide, zinc oxides.
