Overview of zinc sulfide ZnS and its application

 Zinc sulfide ZnS powder overview

Zinc sulfide is an inorganic compound with a chemical formula of ZnS and a molar mass of 97.47 g/mol. The chemical structure of zinc sulfide is very simple, consisting of zinc metal connected to a sulfur atom through a polar covalent bond. This is the main form of zinc found in nature, mainly in the form of the mineral sphalerite. Although this mineral is usually black due to various impurities, the pure substance is white and is widely used as a pigment. In its dense synthetic form, zinc sulfide can be transparent, and it is used as a window for visible optics and infrared optics. Zinc sulfide is yellowish white powder in liquid. It is insoluble in water and has a higher density than water. The main hazard is the hazard to the environment. Measures should be taken immediately to limit spread to the environment.

There are two different crystal forms of solid zinc sulfide, α (wurtzite) and β (sphalerite), which have hexagonal and cubic structures, respectively. Beta crystals (zinc blende) are the more stable form of ZnS.

Application of zinc sulfide ZnS powder

Zinc sulfide 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.

Overview of zinc sulfide ZnS and its application

Luminescent material

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

Catalyst

ZnS fine 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.

Lithium nitride is the only stable alkali metal nitride

圖片
  Overview of Lithium Nitride  Li3N  Powder Lithium nitride is a metallic nitrogen compound with the molecular formula Li3N. It is the only stable alkali metal nitride. It is a purple or red crystalline solid, with a high melting point and a light green luster in reflected light and ruby color in transmitted light. Exposure to the air over a long period of time will eventually result in lithium carbonate. The chemistry of basic metal nitrides is extremely limited, and only lithium nitride is stable and easily prepared among binary compounds (sodium nitrite and potassium nitrite are prepared only under more extreme conditions). Lithium nitride belongs to the hexagonal crystal system. There are lithium and nitrogen layers composed of lithium and nitrogen atoms in lithium nitride crystal. The lithium atoms are arranged like carbon atoms in a graphite crystal, with nitrogen atoms at the center of a hexagon of lithium atoms. There is a lithium layer between the lithium and nitrogen layers.

  Overview of Zinc Sulfide ZnS Zinc sulfide  is a white to off-white or light yellow powder, which becomes darker when exposed to light, stable in dry air, and gradually oxidized to zinc sulfate when stored for a long time in humid air or containing water. Soluble in dilute inorganic acid, soluble in alkali, insoluble in water. Relative density 3.98 (alpha type), (d25) 4.102 (beta type). irritating. Is zinc sulfide fluorescent or phosphorescent? Zinc sulfide  is one of the most common phosphorescent materials. Phosphorescence is a special type of photoluminescence. Unlike fluorescent substances, phosphorescent materials emit absorbed energy immediately. What are the properties of zinc sulfide? Zinc sulfide  is white or slightly yellow powder. Turns into crystals when burned in H2S gas. Its α variant is a colorless hexagonal crystal with a density of 3.98g/cm3 and a melting point of 1700°C. Its beta variant is a colorless cubic crystal with a density of 4.102 g/cm3, which transforms to

  Overview of Tungsten Disulfide Tungsten disulfide  as a potential battery material is also expected to benefit from more market replenishment. Tungsten disulfide is a layered material with remarkable surface effects, electron mobility, thermochemical stability and high electron density of states. It has been widely used for lithium and sodium storage. For example, nanocomposites as conductive additives or graphene composites as battery cathode materials can exhibit higher specific capacity and discharge efficiency, making up for the deficiencies of single-component WS2 or C as anode materials. The advent of sodium batteries is expected to alleviate the current shortage of lithium resources on the rapid development of the new energy industry, and will further stimulate the application of transition metal dichalcogenides such as tungsten disulfide WS2 in the field of power storage.  Lithium-ion batteries are a key raw material for developing energy devices and realizing the vision of &
