Specification of Zinc Sulfide

Zinc sulfide 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.

Is zinc sulfide harmful? 
Chronic: Zinc-containing fumes may cause metal fume fever. Sulfides may cause irritation to the skin, Hydrogen sulfide, if generated, is toxic, a severe irritant and flammable. Effects include conjunctivitis, headache, nausea, dizziness, coughing, pulmonary edema and leading to death. 

Is zinc sulfide soluble in water?
Zinc sulfide 4.1 g/mL at 25 °C(lit.) Soluble in acids. insoluble in water.

Different forms of ZnS：
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.

Military and other cutting-edge technology fields.

The applications of Zinc Sulfide are as following:
 

Zinc sulfide uses
 

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 Iran-2, but this name is now obsolete.
 

Optical materials
 

Pigment：
Zinc sulfide is a common pigment, sometimes called statolith. 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 a brown powder and enhances photocatalytic activity through enhanced light absorption.

FAQs of Zinc Sulfide ZnS Powder：

Q: What is zinc sulfide used for?

A: Zinc sulfide (ZnS) powders are employed in a wide range of applications due to their unique optical, electrical, and chemical properties. They are commonly used as phosphors in cathode ray tubes, LEDs, and other display technologies, where they emit light when excited by electrons or ultraviolet radiation. In the field of optics, ZnS is utilized in infrared windows, lenses, and domes because of its transparency in the mid-infrared region. It also serves as an effective pigment in cosmetics and personal care products, providing opacity and UV protection. Moreover, ZnS powder is integral to the development of advanced materials such as sensors, coatings, and catalysts, taking advantage of its semiconducting behavior and high chemical stability.

Q: Is zinc sulfide safe for human exposure?

A: While bulk zinc sulfide is generally considered less hazardous, fine particles can pose inhalation risks, potentially causing irritation to the respiratory system, eyes, and skin. Proper handling practices should be followed to ensure safety, including the use of personal protective equipment (PPE) like gloves, safety goggles, and appropriate respiratory protection when dealing with airborne dust. Adequate ventilation is important to minimize exposure levels. Adhering to manufacturer guidelines and occupational health standards ensures safe handling. For detailed information on potential health effects and safety measures, always refer to the Safety Data Sheet (SDS) provided by the supplier.

Q: What is the formula and structure of zinc sulfide?

A: Zinc sulfide has the chemical formula ZnS, indicating it consists of one zinc atom (Zn) and one sulfur atom (S). This compound can crystallize in two main forms: the sphalerite cubic structure and the wurtzite hexagonal structure. The wurtzite form features alternating layers of zinc and sulfur atoms arranged in an ABAB stacking sequence, which results in strong covalent bonds between the atoms, contributing to ZnS's robust mechanical properties and thermal stability. The sphalerite structure, on the other hand, is characterized by a face-centered cubic lattice. Both structures are significant for applications requiring high transparency or specific optoelectronic characteristics.

Q: Can zinc sulfide be incorporated into composite materials?

A: Yes, zinc sulfide can be integrated into composite materials to enhance certain properties, such as optical performance, electrical conductivity, and catalytic activity. Composites containing ZnS benefit from its inherent qualities while offering improved design flexibility and functionality. Incorporating ZnS into polymer matrix composites can yield materials with tailored optical properties suitable for use in sensors or photonic devices. When used as a filler in ceramics or glasses, ZnS can improve thermal stability and mechanical strength. Additionally, ZnS nanoparticles can be dispersed within metal matrices to create nanocomposites with enhanced wear resistance and lubricating properties. The versatility of ZnS makes it a valuable component in developing innovative materials across multiple industries, including electronics, optics, and energy.
