Advantages of Zinc Sulfide in the chemical field

What is Zinc Sulfide?
Zinc sulfide is a white or yellowish powder that darkens when exposed to light. It is stable in dry air and will gradually oxidize to zinc sulfate when placed in humid air or contains moisture for a long time. Soluble in dilute inorganic acids, insoluble in water and alkaline solutions. Relative density 3.98 (α type), (d25) 4.102 (β type), irritating. Due to its various excellent properties, it is widely used in many fields.
Metal sulfides have excellent electrical properties and are widely used in semiconductors, pigments, photoluminescent devices, solar cells, infrared detectors, optical fiber communications, etc. Among them, zinc sulfide is widely studied and used in II-VI compounds as one of the materials. How about zinc sulfide?
Advantages of Zinc Sulfide in the chemical field
Zinc sulfide is mainly used in paints and plastics in chemical production. The production of zinc sulfide was first recorded in France in 1783. Due to its white opacity and insolubility with water, organic solvents, strong acids, and weak bases can be considered important pigments. Zinc Sulfide is the second-most important pigment, after titanium dioxide, in the United States but continues to hold a prominent place within European industry. As a bulk material, the commercial grade zinc sulfide with a melting point of 1650°C and a purity of 98% has a Mohs hardness of 3.0 and a refractive index of 2.37. Due to its high refractive index and wear resistance, zinc sulfide pigments are used in equipment, wax paper, and metal plates. Apply a thin layer for high coverage. Zinc Sulfide is simple to disperse and is difficult to form agglomerates. It is a neutral white with excellent optical properties. It is commonly employed as a component in thermosetting plastics, thermoplastics-strengthened fiberglass, fire retardants, synthetic rubber, and dispersants.
Zinc sulfide is very soft and, therefore, less abrasive, and the white elastomer used as a pigment produces soles that last much longer than those made with TiO2.
As a stabilizer, zinc sulfide is also inventively used in some thermoplastics, especially PP and PBT, to improve the thermal stability of polymers. As for the mechanism, there is no conclusive explanation so far. But we believe it is because zinc sulfide can react with most metal ions with catalytic effect to form immobile complexes, avoiding the catalytic degradation caused by these ions entering the polymer lattice, the so-called " Fixed Effect."
In addition, the softness of zinc sulfide gives it an incomparable advantage over TiO2 in processes that require abrasiveness.
