| Zusammenfassung: | PURPOSE:To produce hyperfine tungsten oxide particles in large quantities by a simple means at a low cost by hydrolyzing metal alkoxide with a specified water-in-oil type microemulsion. CONSTITUTION:A water-in-oil type microemulsion consisting of a surfactant, water and a nonpolar org. liq. or further contg. alkanol is prepd. Tungsten alkoxide is added to the microemulsion and hydrolyzed. Columnar or spherical hyperfine tungsten oxide particles having about |
