CAS:18282-10-5丨Tin(IV) Oxide

Tin dioxide is mainly used as a raw material for enamel glaze, porcelain glaze and opal glass. Adding tin dioxide in the glazing process can significantly enhance the covering ability of the glaze, and improve the activity and thermal properties of the glaze, so that the glaze color is white. It is also used as a catalyst to convert carbon monoxide from automobile exhaust to carbon dioxide, a mordant for printing and dyeing, a polish for metal and decorative stone, and a raw material for certain fragrances and cosmetics. It can also be used as a carrier of a variety of colors, mixed with cobalt stannate to make sky blue colors. Tin dioxide is a good emulsion for enamel. It not only has good milky properties, but also can obtain fine Chemicalbook greasy porcelain surface and better luster. Because tin dioxide is easy to form stannate in the process of enamel melting, it is used in grinding in production. The grinding amount is generally 3% to 8% of the glaze block. As the raw material of tin dioxide used as a turbidity agent, the ideal particle is not greater than 1μm, the purity should be above 98% and no metal tin exists, and the amount of iron (Fe2O3) should be less than 0.1%. Although tin dioxide has good performance and non-toxicity, its use is limited due to the high price of raw materials. Tin dioxide is also the main raw material for the manufacture of tin zirconium red pigment (peach pigment).
