Zinc Sulfides An Overview Sciencedirect Topics

zinc sulfide occurs as two polymorphs, cubic sphalerite and hexagonal wurtzite. sphalerite is the stable phase at low temperatures and is a fairly common trace mineral in sulfidic sediments. It forms as a discrete solid phase since Zn is not incorporated to any significant extent within sedimentary pyritezinc sulfide has been useful in making multilayer coatings for use at normal incidence that are antireflecting in the near-uv and violet portion of the visible spectrum but have the full reflectance values of zns for wavelengths less than 2000 17.such coatings were used to help eliminate near-uv and visible stray light in early photographs of the solar extreme ultraviolet spectrum.safety data sheet according to and ghs rev. effective date 01.31.2015 page of zinc sulfide, created by global safety management, inc. -tel: 161 www.gsmsds.com
