ZnS can be used in luminous coatings

What happens when you mix zinc and sulfur?
Mix them (carefully) and at least place them firmly on the laboratory bench. . When the mixture comes into contact with the heated metal rod, a reaction occurs (this reaction is called exotherm; heat is generated) to form zinc sulfide. Zinc sulfide is an inorganic compound with a chemical formula of ZnS and an appearance of white to off-white or light yellow powder. See the light darken.

It is stable in dry air and is gradually oxidized to zinc sulfate when it is placed in humid air for a long time or contains moisture. Converts dilute inorganic acid, can decompose alkali and is insoluble in water. The relative density is 3.98 (α type), (d25) 4.102 (β type). It is irritating. It exists in nature as the mineral sphalerite, which can be prepared by treating zinc salt solution with hydrogen sulfide.
What is the role of zinc sulfide?
Usually used as a white pigment. The alpha ray detector makes it glow. Infrared optics. It is used as a phosphor in a variety of applications, including X-ray screens and cathode-ray tubes
Is ZnS poisonous?
Chronic: Zinc-containing fumes may cause fever from metal fumes. Sulfides may irritate the skin. Hydrogen sulfide, if produced, is toxic, severely irritating and flammable. Effects include conjunctivitis, headache, nausea, dizziness, cough, pulmonary edema and cause death.
Why does ZnS show fluorescence?
The electrons corresponding to some impurities have different energy levels than Zn atoms, so when the cathode ray irradiates the cathode, it lifts the electrons to a different energy level (higher) corresponding to the impurity atoms. Therefore, when these electrons fall back to a lower energy level, it will emit light.
Zinc sulfide powder has always been the most widely used luminescent material. The light emitted by the paint is due to the radiant energy of the alpha and/or beta particles deposited in the luminescent crystal. Almost no light is caused by gamma rays. When the activator is excited, it emits photons.
What is the structure of ZnS?
The lattice parameter of the crystal is 0.541nm. The crystal structure is also called rhombohedral cubic crystal, which can be considered as two interpenetrating fcc lattices, one is sulfur and the other is zinc. Their origins are staggered by a quarter of the diagonal.
Shakhaliban zinc sulfide HD-S is now Venator zinc sulfide
After the German Shahari product was merged by Huntsman of the United States, it was re-established as a Venator company in 2017.
Sachtolith HD-S is imported high-purity zinc sulfide, low-hardness blue-phase white pigment. It is refined by the German SACHTLEBEN company through complex processes such as precipitation, filtration, drying, and high-temperature calcination to remove heavy metal content and has the best particle size (about 0.3 um). ) Of synthetic zinc sulfide. Sachtolith HD-S specification is organic treatment and micro treatment, no large particles, suitable for high-quality applications such as plastics, powder coatings and glass fiber.
