A natural transition from the sphlerite form to the wurtzite form occurs at around 1293.15 K . The melting point is at 1991 K . It has a standard Enthalpy Of Formation of -204.6 k J / Mol at 298 K. The CAS Registry Number is . The Mineral form of zinc sulfide is Sphalerite . Zinc sulfide is a wide- Bandgap Semiconductor Material of the II - VI group. It can be Doped as both N-type Semiconductor and P-type Semiconductor , which is unusual for the II-VI semiconductors. ZnS is a covalently bonded solid. APPLICATIONS ZnS was used by Ernest Rutherford and others in the early years of Nuclear Physics as a Scintillation detector, because it emits light on excitation by x-rays or electron beam, making it useful for x-ray screens and Cathode Ray Tube s. It also exhibits Phosphorescence due to impurities on illumination with blue or Ultraviolet light. Zinc sulfide, with addition of few panels. Zinc sulfide is also used as an Infrared optical material, transmitting from visible Wavelength s to over 12 Micrometre s. It can be used planar as an Optical Window or shaped into a Lens . It is sometimes known by the trademarked names Cleartran or '''Irtran-2'''. SEE ALSO EXTERNAL LINKS
