Tin oxide is an inorganic compound of tin found naturally as the mineral cassiterite. It is used in the synthesis of other chemicals, as pigment in the manufacture of glasses, enamels, and ceramic glazes, and as a polishing powder. Tin is a chemical element with the symbol Sn and atomic number 50. It is a natural component of the earth's crust and is obtained chiefly from the mineral cassiterite, where it occurs as tin dioxide.
