Preparation method of high-purity Ammonium Perrhenate:
High purity Ammonium Perrhenate is prepared by adding ammonium sulfate/ammonium carbonate solution to an ammonia-saturated perrhenic acid solution or a barium perrhenate solution. (Different production methods can be used according to your needs.)
High purity Ammonium Perrhenate Applications:
Industrial Uses: Ammonium PerRhenate (APR) is primarily used as an oxidant and a raw material for rhenium-tungsten filaments.
Ammonium PerRhenate (APR) is widely used in precious metal catalysts in the petrochemical industry, including the production of platinum-rhenium bimetallic reforming catalysts. Ammonium PerRhenate (APR) is an important raw material for the production of rhenium metal powder and is also used as an elemental additive in many rhenium-containing alloys. High-purity Ammonium PerRhenate can be used to produce ultra-high-purity rhenium powder, rhenium targets, alloys, and other rhenium materials suitable for advanced technology. High-purity Ammonium PerRhenate can also be used to prepare standard solutions of rhenium compounds.
Storage Instructions for High-Purity Ammonium PerRhenate:
Storage Precautions: Store in a cool, well-ventilated warehouse. Keep away from sources of fire and heat. Keep the storage temperature below 30°C and the relative humidity below 80%. Store in sealed containers. Store separately from flammable and combustible materials and avoid mixing. The storage area should be equipped with suitable materials to contain leaks.
