Tungsten Chemical

Our tungsten chemicals can be used in a variety of ways.
First and foremost, however, they serve as precursors for various catalysts such as DeNOx catalysts, which are used for flue gas denitrification

We produce high-performance tungsten chemicals such as ammonium paratungstate, ammonium metatungstate, tungstic acid, tungsten oxide, and sodium tungstate with various properties suitable for your chemical application.

Tungsten chemicals and their properties

Ammonium paratungstate is a white, crystalline powder with very high chemical purity. It is needed primarily as a universal intermediate product in the production of tungsten oxides, tungstic acid, ammonium metatungstate, and organometallic components. The compound is also used in catalysis and fine chemistry. Tungstic acid is a very finely grained yellow powder with an extremely narrow grain-size distribution, excellent chemical purity, high reactivity, and a uniform morphology. Its unique production properties allow for special applications in homogeneous and heterogeneous catalysis, fine chemistry, and surface coating technology, as well as in the production of organometallic tungsten compounds.
