Ammonium Heptamolybdate

Introduction

Ammonium Heptamolybdate, also known as ammonium paramolybdate, has high water solubility. Ammonium Heptamolybdate is an important intermediate product in the molybdenum metallurgy process due to its high purity, intact crystal form, smooth surface, large and uniform particle size, which is beneficial to deep processing. Ammonium Heptamolybdate is an important raw material for the production of high-purity molybdenum trioxide, molybdenum powder, doped molybdenum powder and other molybdenum products, as well as various molybdenum processing materials (such as photovoltaic power sources, electronic materials, nuclear energy materials, aerospace materials, etc.) precursor. Ammonium Heptamolybdate is widely used in the production of petrochemical catalysts, especially acrylonitrile catalysts, coal liquefaction catalysts, etc., and also in the production of molybdenum carbide, molybdenum nitride precursors, ceramic glazes, pigments and trace fertilizers. 

The production process methods of Ammonium Heptamolybdate mainly include: evaporative cooling crystallization method, acid precipitation method and combined method.
