Tin Oxides

These stannic oxides are produced thermally from high purity tin metal. The powders, comprised of spherical primary particle aggregates, are inert and non hazardous. Applications are found in glaze opacifiers, pigments, electronic ceramics, capacitors, special refractories , chemicals, lapidary and lens polishing . Tin IV Oxide C.A.S. No ( 18282-10-5 ). CCCN 2825 90300.
