Product specifications and grades:
Purity of 4N, main content :NH4ReO499.99,Re69.4
Purity of 5N, main content: nh4reo499.999,Re69.41 brief description
Ammonium perrhenate, also known as ammonium perrhenate, is an oxidant, slightly soluble in cold water and easily soluble in hot water.
The theoretical content of rhenium in ammonium perrhenate is 69.41493... , due to the existence of crystallized water and other trace impurities in the actual products, the theoretical content generally cannot be reached. Rhenium content of more than 69.41, ammonium perrhenate content of more than 99.999 (the total amount of metal impurities containing less than 10ppm) can be called ultra-high pure ammonium rhenate, is the highest level of chemical quality in real products.
[application]
Ammonium perrhenate is widely used in precious metal catalysts in petrochemical industry to produce pt-rhenium bimetal reforming catalysts. Ammonium perrhenate is an important raw material for the production of rhenium metal powder, and is also used as an element additive in many rhenium alloys.
