Violet tungsten oxide for preparing heat insulation coating is a kind of tungsten oxide, whose appearance is fine violet crystal powder. The violet tungsten oxide powder, whose phase composition is W18O49, is a tungsten oxide product developed in China in recent years. Since violet tungsten oxide powder has the largest mesopore volume, the smallest micropore volume, the narrowest pore size distribution, the smallest fractal dimension, the largest average pore size and specific surface area, it is the preferred material for…
