  • Processes for the preparation of stannic oxide
    Patent number: 9102996
    Abstract: Disclosed herein are processes for oxidising Sn2+ dissolved in an aqueous solution to stannic compounds using NO2 and optionally O2 as oxidants, wherein the aqueous solution is kept at a pH in the range of 0 to 7, wherein a salt Sn2+(Xn?)2/n and the oxidants are used according to the reaction scheme a Sn2+(Xn?)2/n +b O2+c NO2??stannic compounds in which scheme a, b and c are mole numbers; with the proviso that when b is essentially zero, then the aqueous solution is essentially free of Cl?, HSO4? and SO42?.
    Type: Grant
