VANADIUM OXIDE, METHOD FOR PREPARING THE SAME, DIELECTRIC COMPOSITION COMPRISING THE SAME

摘要

PURPOSE: A vanadium oxide, a manufacturing method thereof and a dielectric composition including the same are provided to enhance dispersibility by quantitively coating the vanadium composition on colloidal silica. CONSTITUTION: A vanadium oxide is composed of colloidal silica, metal, and vanadium which are successively coated. The metal coated on the colloidal silica is aluminum (Al) or vanadium (V). The metal-coated colloidal silica and vanadium are included at the weight ratio of 7:1-10:1. The colloidal silica is in monodisperse state. The vanadium is vanadium oxy isopropoxide. A manufacturing method of the vanadium oxide comprises the following steps: coating colloidal silica with metal; and coating the metal coated colloidal silica with vanadium.
