ANTIMONY-TIN OXIDE FINE PARTICLE FOR SOLAR RADIATION SHIELDING, DISPERSION LIQUID FOR FORMING SOLAR RADIATION SHIELDING BODY USING THE SAME, SOLAR RADIATION SHIELDING BODY AND TRANSPARENT BASE MATERIAL FOR SOLAR RADIATION SHIELDING

摘要

PROBLEM TO BE SOLVED: To clarify the physical properties of ATO (Antimony-Tin-Oxide) fine particles that a high visible light transmissivity, a low solar radiation transmissivity and a low haze value can be exhibited when formed on a transparent base material or inside the base material, and to produce ATO fine particles having the same physical properties.;SOLUTION: The ATO fine particles having physical properties that the diameter of crystallites composing them is 4 to 125 nm, and the specific surface area thereof is 5 to 110 m²/g can exhibit the above optical properties. As one example for producing the same, an antimony chloride alcoholic solution and an aqueous solution of ammonium hydrogencarbonate are parallelly dripped, thereafter, the resultant precipitates are sufficiently washed and dried, and baking is performed in an air atmosphere to produce the ATO fine particles.;COPYRIGHT: (C)2004,JPO
