Product name: Zinc Oxide (99.9%)
Price: FOB China $2698/MT
Zinc oxide crystallizes in two main forms, hexagonal wurtziteand cubic zincblende. The wurtzite structure is most stable at ambient conditions and thus most common. The zincblende form can be stabilized by growing ZnO on substrates with cubic lattice structure. In both cases, the zinc and oxide centers are tetrahedral, the most characteristic geometry for Zn(II).
In addition to the wurtzite and zincblende polymorphs, ZnO can be crystallized in the rocksalt motif at relatively high pressures about 10 GPa.
Hexagonal and zincblende polymorphs have no inversion symmetry (reflection of a crystal relative to any given point does not transform it into itself). This and other lattice symmetry properties result in piezoelectricity of the hexagonal and zincblende ZnO, and pyroelectricity of hexagonal ZnO.
