Overview of zinc sulfide:

Zinc sulfide is white to off-white or light yellow powder, and the color becomes darker when it is light.It is stable in dry air,and when it is stored in humid air for a long time or contains water,it gradually oxidizes to zinc sulfate. It is soluble in dilute inorganic acid,soluble in alkali,Insoluble in water.Relative density 3.98 (α type),(d25) 4.102 (β type).Irritating.

Application of zinc sulfide:

Zinc sulfide is usually made from waste materials and used for other purposes. Typical sources include smelters,slag,and pickling liquid.It is also a by-product of methane synthesis of ammonia,where zinc oxide is used to remove hydrogen sulfide impurities in natural gas.

High-purity crystalline zinc sulfide powder is an important basic material,which is 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 and long-wave far-infrared precision guidance and far-infrared imaging,Especially in the field of national defense,military and other cutting-edge technologies.The applications of zinc sulfide are as follows: Luminescent material

Zinc sulfide,plus 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 an 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 emit light for a long time and has the familiar dark green luminescence effect. Copper-doped zinc sulfide("ZnS+Cu")is also used in electroluminescent panels.It also exhibits phosphorescence due to impurities in blue or ultraviolet light.

 Optical materials

Zinc sulfide is also used as an infrared optical material,which transmits from visible light wavelengths to just over 12 microns. It can be used as a flat surface for optical windows or as the shape of a lens. It is made of hydrogen sulfide gas and zinc vapor Microchip, 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 transparent form of water,called Cleartran(trademark)The early commercial form was sold in the form of Irtran-2,but this name is now obsolete.


Zinc sulfide is a common pigment,sometimes called sachtolith.When combined with barium sulfate,zinc sulfide forms lithopone.


The fine ZnS powder is an effective photocatalyst,which generates hydrogen from water when illuminated.Sulfur vacancies can be introduced into the ZnS during the synthesis process.This gradually turns the white to yellow ZnS into a brown powder and passes through the enhanced light Absorption enhances the photocatalytic activity.
