What can you do with zinc sulfide?
What is Zinc Sulfide?
Zinc sulfide's chemical formula is ZnS. Zinc sulfide is white to yellow powder or crystal. It is poorly soluble in water and glows from exposure to alpha particles. Zinc sulfide mainly exists in the form of sphalerite and wurtzite. Both of these structures are wide bandgap semiconductor materials and are widely used in optoelectronic devices. The structure of sphalerite is a cubic crystal system with a bandgap of 3.54eV at 300K. Wurtzite structure is hexagonal and the bandgap is 3.91eV. The pure sphalerite will change to wurtzite at 1020°C, but the presence of impurities will lower the temperature.
Is zinc sulfide harmful?
Chronic: Zinc-containing fumes may cause metal fume fever. Sulfides may cause irritation to the skin, ... Hydrogen sulfide, if generated, is toxic, a severe irritant, and flammable. Effects include conjunctivitis, headache, nausea, dizziness, coughing, pulmonary edema, and leading to death.
Physicochemical properties of zinc sulfide
Zinc sulfide physical properties
Zinc sulfide is a white or slightly yellow powder. It turns into crystals when burning in H2S gas. Its alpha variant is a colorless hexagonal crystal with a density of 3.98g/cm3 and a melting point of 1700°C. Its beta variant is a colorless cubic crystal with a density of 4.102g/cm3, which is transformed into an alpha type at 1020°C. Zinc sulfide exists in sphalerite. Insoluble in water, soluble in acid. See the sunlight dimmed.
Zinc sulfide chemical properties
Zinc sulfide is converted into zinc sulfate in humid air for a long time. It is generally derived from the action of hydrogen sulfide and zinc salt solution. If a small amount of Cu, Mn, Ag is added as an activator in the crystalline ZnS, it can emit different colors of fluorescence after being illuminated. Zinc sulfide can be used as analytical reagents and coatings. It can be used to make paint, opaque glass, rubber, plastic, and phosphor.
Is ZnS an acid or base?
It is obvious that ZnS is stable in acidic pH when Eh is below zero. At alkaline pH, however, ZnS is stable at a more negative Eh value. The oxidation product of ZnS is zinc sulfate in acidic solution and zinc hydroxide precipitate in alkaline solution.
Is zinc sulfide a fluorescent material?
Zinc sulfide is one of the most common phosphorescent materials. Phosphorescence is a special type of photoluminescence. Unlike fluorescent substances, a phosphorescent material emits absorbed energy at once.
What can you do with zinc sulfide?
The most common use of ZnS is as a pigment for paints, plastics, and rubber. Lithopone, a mixture of ZnS and barium sulfate (BaSO4), is a widely used pigment for low-gloss paints. ZnS is phosphorescent, which makes it useful for several electronic and decorative applications.
