Tungsten Oxide

The thermal degradation method is a process for the preparation of ammonium metatungstate based on ammonium paratungstate (APT). This method is also the mainstream process of preparing ammonium metatungstate (AMT). At present, China's industrial use of pyrolysis equipment is mainly rotary calciner, at the same time, there are a number of applications in other countries for AMT patented pyrolysis equipment, microwave heating furnace is one of them. Because the microwave energy level is close to the vibrational level of the water molecule, the hydrous material can dehydrate rapidly under the microwave field, which is also the working principle of the microwave heating furnace. Microwave heating furnace operating characteristics are: 1. Uniform and fast, which is the main characteristics of microwave drying. As the microwave has a large penetration capacity, heating can be generated directly within the medium heat, and the drying speed; 2. Selective, microwave heating...
