Is zinc sulfide an inorganic compound?
Zinc sulfide is an inorganic compound with the chemical formula ZnS. It is the main form of zinc in nature, and zinc mainly exists in the form of the mineral sphalerite. Although minerals are usually black due to various impurities, pure substances are white, so they are widely used as pigments. Is zinc sulfide soluble in water? Zinc sulfide is soluble in acid. not soluble in water.

Is zinc sulfide poisonous?
Chronic: Zinc-containing fume may cause metal fume fever. Sulfide may irritate the skin. If hydrogen sulfide is produced, it is toxic, with severe irritation and flammability. Effects include conjunctivitis, headache, nausea, dizziness, cough, pulmonary edema and cause death.

How many forms of ZnS exist in nature?
ZnS exists in two main crystal forms, and this duality is usually a prominent example of polymorphism. In each form, the coordination geometry of 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 is also called a very rare mineral, called spherulitic phosphate, with the chemical formula (Zn, Hg)S.

What is the use of zinc sulfide?
The most common use of zinc sulfide is as a pigment for paints, plastics and rubber. Lithopone is a mixture of zinc sulfide and barium sulfate (BaSO4), a pigment widely used in low gloss coatings. ZnS is phosphorescent, which makes it useful for a variety of electronic and decorative applications.
High-purity crystalline zinc sulfide powder is an important basic material, which is widely used in high-tech fields such as civil, military, and aerospace. 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. Frontier technology fields such as military.

White Pigment Zinc Sulfide for Coloring Glass Fiber Reinforced Plastic
Titanium dioxide is the most important inorganic pigment. There are three crystal types of titanium dioxide in nature: rutile (tetragonal system), anatase (tetragonal system) and brookite (orthogonal system). The high hardness of redstone type is a disadvantage for dry glass fiber reinforced plastics, because rutile will damage the glass fibers during the coloring process, causing serious loss of the mechanical strength of the plastic product. Therefore, the white pigment for coloring glass fiber reinforced plastics is selected from zinc sulfide, which has slightly poorer optical properties and is softer.
