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.sulfide also spelled: sulphide. sulfide mineral, sulfide also spelled sulphide, any member of a group of compounds of sulfur with one or more metals. Most of the sulfides are simple structurally, exhibit high symmetry in their crystal forms, and have many of the properties of metals, including metallic lustre and electrical conductivity. Sphalerite is a mineral, mixed with zinc and iron sulfide. The chemical formula of Sphalerite is (Zn, Fe)S.
