METHOD FOR THE PREPARATION OF HIGH PURITY STANNOUS OXIDE |
摘要 |
Provided herein are methods for the preparation of high purity stannous oxide comprising: (a) reacting a Sn salt with a C2-12 dicarboxylic acid in the aqueous phase to form a suspension comprising a Sn-dicarboxylate complex; (b) washing the Sn-dicarboxylate complex with water to obtain a wash solution comprising a washed Sn-dicarboxylate complex essentially free of the anion of the Sn salt; and (c) reacting the washed Sn-dicarboxylate complex with a base to form high purity SnO, wherein the high purity SnO has an alpha radiation count of less than about 0.002 cph/cm2.
