What crystal type is zinc sulfide


The tetra structure of sphalerite, or the hexagonal structure of wurtzite, what crystallography doesn't say is that the smallest ring should be the smallest cell structure; this is in any material science book. ZnS is two of the ten most basic structures. The electronegativity difference between Zn-S is too small, far less than the minimum 1.7 for forming ionic bonds, and can only form covalent bonds. It is an atomic crystal because it forms a spatial network structure similar to SiC. In geometric crystallography, according to the symmetry of a crystal, a crystal can be divided into seven crystal systems, 32 macroscopic symmetry types and 230 microscopic symmetry types. [Zinc sulfide] chemical formula ZnS, formula quantity 97.43. White or yellowish powder. The α variant is a colourless hexagonal crystal with a density of 3.98 g/cm 3 and a melting point of 1700±28(202.66 kph -- 20 atmospheres). The β variant is a colourless cubic crystal with a density of 4.102 g/cm 3 and is converted to α type at 1020. Insoluble in water, easily soluble in acid. See, the sunlight darkens. Long-standing moist air is changed into zinc sulfate. If Cu, Mn and Ag are added to ZnS crystal as activators, different fluorescence colours can be emitted after illumination. Used for analytical reagents, coatings, paints, white and opaque glass, rubber, plastic filling, and for the preparation of phosphors. It's made of zinc and sulfur.
