Ammonium Paramolybdate offered is crystalline white colored water soluble powdery white (or colorless) substance that has yellowish or greenish shade. With the crystals being soluble in water as well as being stable in air, the application of ammonium paramolybdate is based on its chemical as well as physical properties where as a good catalyst in organic synthesis, it is used in chemical reactions for production of various molybdenum compounds. Further, it is also used as pigment, in production of molybdenum metal, in analytical reagent, in de-sulphurization of petroleum as well as in coal processing applications.

Ammonium Paratungstate offered comprises a white crystalline salt of ammonium & tungsten and has chemical formula of (NH4)10(W12O41)·5H2O. Also known as APT, it is used as a fundamental intermediate for downstream manufacturing of most of tungsten materials as well as in tungsten-bearing catalysts. Made available in form of a white crystalline powder with minimum WO3 content of 88.5%, it is used as reagent or as source for highly-pure tungsten metal powder, carbide or tungstic acid. Some other applications include in field of absorbent gels, as coloring agent in porcelain industry, as ceramic additives, as sintered metal additives and others.
