How to store zinc sulfide powder?

Overview of Zinc Sulfide ZnS

Zinc sulfide is a white to almost white or light yellow powder that darkens in color when exposed to light. Stable in dry air, gradually oxidized to zinc sulfate when stored in humid air or with water for a long time. Soluble in dilute inorganic acids, soluble in alkalis, insoluble in water. Relative density 3.98（ α Type, (d25) 4.102（ β Type). It is stimulating.

Application of Zinc Sulfide ZnS

Zinc sulfide is usually made from waste and used for other purposes. Typical sources include smelters, slag, and pickling solution. It is also a byproduct of methane to ammonia synthesis, with zinc oxide used to remove hydrogen sulfide impurities from natural gas.

High purity crystalline zinc sulfide powder is an important basic material widely used in high-tech fields such as civil, military, aerospace, etc. It is also an extremely important window material for medium to long wave far-infrared precise guidance and far-infrared imaging, especially in cutting-edge technology fields such as national defense and military. The application of zinc sulfide is as follows: luminescent material.

Zinc sulfide, combined 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 an activator, the resulting color is bright blue with a maximum wavelength of 450 nm. When using manganese, it produces an orange red color of approximately 590 nm. Copper can emit light for a long time and has the familiar dark green emitting 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 material

Zinc sulfide is also used as an infrared optical material, which can transmit visible light wavelengths to slightly higher than 12 microns. It can be used as a plane or lens shape for optical windows. It is made of hydrogen sulfide gas and zinc vapor microchips, sold in FLIR grade (forward looking infrared), with zinc sulfide appearing milky yellow in an opaque form. When subjected to hot isostatic pressing (HIPed), the material can be transformed into a transparent form of water, known as Cleartran (trademark). The early commercial form was sold in the form of Irtran-2, but this name is now outdated.

pigment

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

catalyzer

Fine ZnS powder is an effective photocatalyst that produces hydrogen gas from water under illumination. During the synthesis process, sulfur vacancies can be introduced into ZnS. This gradually turns white to yellow ZnS into brown powder and enhances photocatalytic activity through enhanced light absorption.

How to store zinc sulfide powder

Store in a ventilated and dry warehouse; Avoid outdoor storage. The container must be sealed to prevent moisture.

Zinc sulfide has stable properties.

1. If used and stored according to specifications, it will not decompose and there are no known hazardous reactions. Contact with oxides and acids should be avoided.

2 α- ZnS is a colorless hexagonal crystal; Relative density 3.98, melting point 1700 ± 20 ℃ (5.066 × 106Pa), sublimation above 1180 ℃. Almost insoluble in water and acetic acid, easily soluble in other acids. β- ZnS is a colorless cubic crystal; Relative density 4.102 (25 ℃), transition temperature 1020 ℃; Almost insoluble in water, easily soluble in acids.

Is zinc sulfide toxic?

Zinc sulfide is toxic, corrosive, and has a stimulating effect on the skin. A large amount of zinc entering the body can cause dizziness, vomiting, and diarrhea. Therefore, operators should wear work clothes and protective equipment. The workshop should have good ventilation.
