METHOD FOR PRODUCING TIN DIOXIDE PRECURSOR PARTICLE, AND METHOD FOR PRODUCING TIN DIOXIDE PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a tin dioxide precursor suitable for obtaining tin dioxide not requiring grinding after calcination, in a method for producing tin dioxide by calcining the tin dioxide precursor.;SOLUTION: A tin dioxide precursor particle has a flaky particle shape, and contains 60-80 wt% Sn, and 1-15 wt% organic matter on the basis of C. In a method for producing the tin dioxide precursor particles in which a tin (II) salt is neutralized in an aqueous medium to obtain a hydrolyzate, then cleaned and subjected to solid-liquid separation, at least one kind of organic matter selected from citric acid, lactic acid and amino acid is added into the aqueous medium during neutralization and/or after neutralization.;COPYRIGHT: (C)2013,JPO&INPIT
