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 preparing ultrafine tungsten powder, nano tungsten powder, photocatalytic materials, petroleum catalysts, and microelectronic integrated circuit boards.
In other words, the reason why the violet tungsten oxide powder can be used for the preparation of the heat insulating coating material is because it has good ultraviolet heat insulation performance, near infrared heat insulation performance, and excellent visible light transmittance. Therefore, the thermal insulation coating of violet tungsten oxide has a wide application in the fields of construction, automobiles, and the like.
