Nanometer violet tungsten oxide may be applied in thermal insulating glass, such as sun room, exhibition hall, villa, office building, car, cruise ship, and airplane, etc. Violet tungsten oxide can also be used for preparing ultrafine tungsten carbide powder. In order to prepare ultrafine tungsten carbide powder with excellent performance, some scholars selected violet tungsten oxide and blue tungsten oxide as raw materials, studied the process of preparing tungsten powder by reduction of violet tungsten oxide and producing tungsten carbide…

Nanometer violet tungsten oxide may be applied for producing heat insulation coating, and therefore be used in building, car and airplane where require high heat insulation and high transparency. Violet tungsten oxide can also replace blue tungsten oxide for hydrogen reduction to produce tungsten powder. Compared with tungsten powder prepared by using blue tungsten oxide as raw material, the tungsten powder produced by adopting violet tungsten oxide as raw material has the following advantages: the production capacity can be increased…

Nanometer violet tungsten oxide may be applied for producing thermal insulation coating, and therefore be used as a raw material for preparing thermal insulation film. With the improvement of people’s living standards and the awareness of environmental protection, people are pursuing more environmentally friendly thermal insulation films. Therefore, thermal insulation film of violet tungsten oxide with excellent heat insulation and environmental protection properties is sought-after. The violet tungsten oxide has unique needle-like crystal shape with a large gap therebetween, and…

Nanometer violet tungsten oxide may be applied for producing near-infrared shielding material. Violet tungsten oxide can be prepared by APT light reduction method. In this process, other process conditions remain unchanged: 1. If the furnace temperature is relatively high, the morphology of the formed violet tungsten oxide is rod-like crystal. 2. If the furnace temperature is relatively low, the morphology of the obtained violet tungsten oxide is needle-shaped crystal. Both rod-like crystal and needle-shaped crystal are intrinsic crystal forms of…

Nanometer violet tungsten oxide may be used to produce “transparent” thermal insulation paper, which is applied in building and car for high heat insulation and high visible light transmittance. Violet tungsten oxide can be prepared by APT light reduction method. In order to determine the optimal process conditions for the production of violet tungsten oxide, some scholars have carried out a large number of experiments. They studied various process parameters affecting the production of violet tungsten oxide, such as furnace…

Nanometer violet tungsten oxide may be applied for preparing thermal insulation film, and thus be used in architectural glass such as sun room, exhibition hall, hotel, villa, high-rise apartment, and high-grade automotive glass. Violet tungsten oxide can be prepared by APT mild reduction method. In order to study the influence of APT raw materials on the production of violet tungsten oxide, some scholars have used two types of APT raw materials to proof it. They are APT prepared by intermittent…

Nanometer violet tungsten oxide may be applied for producing ceramic microsphere. Violet tungsten oxide can be prepared by using APT as raw material. This process also requires the material – liquid ammonia. The quality requirements for liquid ammonia are: ammonia≥99.80%, residue≤0.20%. The main equipment used is industrial rotary tube furnace. Preparation of violet tungsten oxide. The dried APT was quantitatively fed into the industrial rotary tube furnace, through which NH3 was passed by a screw conveyor. And APT was calcined…

Nanometer violet tungsten oxide may be used for the preparation of thermal insulation masterbatch, which has good thermal insulation and weather resistance. And therefore it can be applied for the production of thermal insulation films and other thermal insulation products. Violet tungsten oxide can also be used to prepare fine and uniform tungsten powder and tungsten carbide powder with good dispersibility. Ultrafine tungsten carbide-based cemented carbides have attracted increasing interest due to their excellent physical and mechanical properties such as…
