About Zinc Sulfide ZnS Powder
Zinc sulfide (or zinc sulfide) is an inorganic compound with the chemical formula ZnS. It is the main form of zinc in nature, and zinc mainly exists in the form of the mineral sphalerite. Although the mineral is usually black due to various impurities, the pure material is white, so it is widely used as a pigment. Zinc sulfide can be transparent in a dense synthetic form and serves as a window for visible optics and infrared optics.
ZnS exists in two main crystal forms, and this duality is usually a prominent example of polymorphism. In each form, the coordination geometry at Zn and S is a tetrahedron. The more stable cubic form is also called zinc blend or sphalerite. The hexagon is also called the mineral wurtzite, although it can also be produced synthetically. The transition from sphalerite form to wurtzite form occurs at around 1020°C. The tetragonal crystal form is also called a very rare mineral, called spherulitic phosphate, with the chemical formula (Zn, Hg)S.
Zinc sulfide is a crystalline solid used for semiconductor and optical applications. TRUNNANO can produce many standard grades, including technical grade, food, agricultural and pharmaceutical grade, optical grade, and follow Applicable ASTM test standards.

How is Zinc Sulfide ZnS Powder Produced?
Zinc sulfide is usually made from waste materials for other purposes. Typical sources include smelters, slag, and pickling liquor. It is also a by-product of ammonia synthesis from methane, where zinc oxide is used to remove hydrogen sulfide impurities in natural gas.
Applications of Zinc Sulfide ZnS Powder
High-purity crystal zinc sulfide powder is an important basic material widely used in high-tech fields such as civil, military, aerospace, and other high-tech fields. It is also an extremely important window material for medium-long-wave far-infrared precision guidance and far-infrared imaging, especially in national defense. Military and other cutting-edge technology fields. The applications of Zinc Sulfide are as following:
Luminescent material
Zinc sulfide, coupled with a small amount of suitable activator, has strong phosphorescence and is currently used in various applications from cathode ray tubes to X-ray screens to emit light in dark products. When silver is used as the activator, the resulting color is bright blue with a maximum of 450 nm. The use of manganese produces an orange-red color of about 590 nm. Copper can glow for a long time and has the familiar dark green glow effect. Copper-doped zinc sulfide ("ZnS + Cu") is also used in electroluminescent panels. It also exhibits phosphorescence due to impurities under blue or ultraviolet light irradiation.
Optical materials
Zinc sulfide is also used as an infrared optical material, transmitting from visible light wavelengths to just over 12 microns. It can be used as a flat surface as an optical window or shaped as a lens. It is made of hydrogen sulfide gas and zinc vapor to make microchips and sold as FLIR grade (front looking infrared), in which zinc sulfide is in creamy yellow, opaque form. When hot isostatic pressing (HIPed), the material can be converted into a transparent form of water, called Cleartran (trademark). Early commercial forms were sold as Irtran-2, but this name is now obsolete.
Pigment
Zinc sulfide is a common pigment, sometimes called sachtolith. When combined with barium sulfate, zinc sulfide forms lithopone.
Catalyst
The fine ZnS powder is an effective photocatalyst, generating hydrogen from water when illuminated. Sulfur vacancies can be introduced into ZnS during the synthesis process. This gradually turns white to yellow ZnS into brown powder and enhances photocatalytic activity through enhanced light absorption.
Feature of Zinc Sulfide ZnS Powder:
Zinc sulfide CAS 1314-98-3 is white to off-white or light yellow powder. See the light color becomes darker. Stable in dry air, gradually oxidized to zinc sulfate when placed in moist air for a long time or containing moisture. Soluble in dilute mineral acid, soluble in alkali, insoluble in water. The relative density is 3.98 (α-type), (d25) 4.102 (β-type). Irritating.
