MANUFACTURING METHOD FOR ANTIMONY-CONTAINING TIN OXIDE FINE PARTICLES FOR FORMING SOLAR RADIATION SHIELDING BODY, DISPERSION FOR FORMING SOLAR RADIATION SHIELDING BODY, SOLAR RADIATION SHIELDING BODY, AND SOLAR RADIATION SHIELDING BASE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide: a manufacturing method for antimony-containing tin oxide fine particles which have excellent dispersibility and solar radiation-shielding properties; a dispersion for forming a solar radiation-shielding body using the antimony-containing tin oxide fine particles manufactured by the manufacturing method, a solar radiation-shielding body, and a base material for solar radiation-shielding.;SOLUTION: The manufacturing method for the antimony-containing tin oxide fine particles for solar radiation-shielding includes: parallel-dropping an alcohol solution in which an antimony compound is dissolved and an alkali solution to a tin compound solution having a temperature of 50°C or lower; or parallel-dropping a tin compound solution and an alcohol solution in which an antimony compound is dissolved to an alkali solution having a temperature of 50°C or lower to generate a hydroxide containing tin and antimony, to thereby obtain a precipitate; subjecting the precipitate to decantation, to thereby obtain a filtered washed material; subjecting the washed material to wet treatment with an alcohol solution and drying thereafter, to thereby obtain a precursor of antimony-containing tin oxide fine particles; and calcinating the precursor.;COPYRIGHT: (C)2009,JPO&INPIT
