History of Zinc sulfide ZnS powder

Overview of Zinc sulfide ZnS powder

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 when placed in humid air for a long time or contains moisture, it will gradually oxidize to zinc sulfate. Soluble in dilute inorganic acid, soluble in alkali, insoluble in water. The relative density is 3.98 (α type), (d25) 4.102 (β type). It is irritating.

Zinc sulfide ZnS powder history

The study of zinc sulfide fluorescent materials has a history of more than 130 years since it was discovered by the French chemist Sidot in 1868. From the 1920s to the 1940s, the study of zinc sulfide materials has always attracted people's attention.

Application of Zinc sulfide ZnS powder

Zinc sulfide ZnS powder is usually made from scrap and used for other purposes. Typical sources include smelters, slag and pickling liquor. It is also a by-product of ammonia synthesis from methane, in which 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, etc., and is also an extremely important medium and long wave window material. Far-infrared precision guidance and far-infrared imaging, especially in frontier technical fields such as national defense and military. The uses of zinc sulfide are as follows.

Luminescent materials

Zinc sulfide ZnS powder, with a small amount of suitable activator, has a 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 color produced 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 luminous effect. Copper-doped zinc sulfide ("ZnS+Cu") is also used in electroluminescent panels. It also shows phosphorescence due to impurities in blue or ultraviolet light.

 Optical materials

Zinc sulfide ZnS powder is also used as an infrared optical material, which can transmit visible light wavelengths to a little over 12 microns. It can be used as the plane of the optical window or as the shape of the lens. It is made of hydrogen sulfide gas and zinc vapor microchips and is sold as FLIR grade (front looking infrared), where zinc sulfide is in a creamy yellow, opaque form. When hot isostatic pressing (HIPed), the material can be transformed into a transparent water form called Cleartran (trademark). The early commercial form was sold in the form of Irtran-2, but this name is now obsolete.

Pigment

Zinc sulfide ZnS powder is a common pigment, sometimes called sandstone. When combined with barium sulfate, zinc sulfide forms Lithopone.

Catalyst

Zinc sulfide ZnS powder is an effective photocatalyst, which generates hydrogen from water under light. 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.
