WebOct 26, 2024 · Zinc sulfide (ZnS), a naturally occurring salt, is the main source of zinc. It has two common crystalline forms (polymorphs): Sphalerite (“zinc blende”), with a cubic crystal structure, is the form that predominates in nature. Wurtzite, with hexagonal crystals, is scarcer, but it can be made by heating sphalerite to ≈1020 ºC. 1
