Room-temperature solid-state reaction to nanowires of zinc sulfide Occurrence: Zinc sulfide occurs naturally as the mineral zinc blende, also called sphalerite, which is a mixture of iron and zinc sulfides. We get two moles of zinc oxide and two moles of sulfur dioxide. You will immediately notice that hydrogen sulfide gas is a product, and you will wish you had done this in the fume hood. 5 years ago. Zinc 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 Å [17].Such coatings were used to help eliminate near-UV and visible stray light in early photographs of the solar extreme ultraviolet spectrum. The time dependence of the photocorrosion was examd. Combustion Reactions Oxidation-reduction reactions break down into four types: combination and decomposition, single and double displacement, combustion and disproportionation.
