Producing Fine Particle Violet Tungsten Oxide

Fine tungsten powder used more widely, it also makes the study of ultrafine tungsten powder is increasing. Currently the producing method of ultrafine tungsten powder has three main research directions: First, to improve the blue tungsten process. Second, the introduction of new reduction methods, such as hydrogen halide reduction and the third is the use of laser and other new fluidized technology. The study found that using violet tungsten oxide to producing fine particles of tungsten powder is good than using blue tungsten oxide so the producing fine particles of tungsten powder the violet tungsten as material is more popular than blue tungsten oxide. But violet tungsten powder particle sizes also will influent tungsten powder size and properties. Fine violet tungsten powder can produce good properties fine particles so to produce fine particles violet tungsten oxide has a certain significance and role for fine tungsten powder. Producing process as follows:
1. The amount of APT loaded boa then push into hot zone of reduction furnace, while feeding a certain proportion of mixed gas which is hydrogen and water vapor, heated to a predetermined temperature to cool for a while after being room temperature draw a charge
2. In the heating, keeping, cooling process, the gas flow rate remains constant.
3. Using WLP202 type fsss analyzer to analysis raw material and product and the phase of the product analysis by the x-ray diffraction.
