PRECURSOR PARTICLE FOR TIN DIOXIDE, METHOD FOR PRODUCING THE SAME, AND METHOD FOR PRODUCING TIN DIOXIDE USING THE PRECURSOR PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide precursor particles for tin dioxide, which are suitable for obtaining tin dioxide not requiring pulverization after firing in a method for producing tin dioxide by firing a precursor for tin dioxide.;SOLUTION: The precursor particles for tin dioxide have a flaky shape, and contain 60-88 wt.% Sn and 1-15 wt.%, based on C, of an organic substance. In a method for producing the precursor particles for tin dioxide, a tin(II) salt is neutralized in an aqueous medium to obtain a hydrolysate, which is subjected to washing and solid-liquid separation, and at least one kind of organic substance selected from citric acid, lactic acid, and amino acids is added into the aqueous medium during neutralization and/or after neutralization.;COPYRIGHT: (C)2008,JPO&INPIT
