Description

Perrhenate is an inorganic salt containing the perrhenate anion (ReO₄⁻), a key source of rhenium in various high-tech applications. This compound is valued for its role as a versatile precursor in catalysis and advanced materials synthesis. It is essential for industries involved in petroleum refining, aerospace engineering, and specialized chemical manufacturing where rhenium's unique properties are leveraged.

Application

• Catalyst Manufacturing: Serves as a critical precursor for platinum-rhenium (Pt-Re) and other rhenium-based catalysts used in petroleum reforming processes to produce high-octane gasoline.
• Superalloy Production: Used in the preparation of rhenium metal, a vital component in nickel-based superalloys for jet engine turbine blades and other high-temperature components.
• Radiopharmaceuticals: Acts as a starting material for the production of Rhenium-188 and Rhenium-186 isotopes used in targeted cancer therapy and diagnostic imaging.
• Electroplating: Employed in electroplating baths to deposit rhenium coatings, which provide exceptional wear and corrosion resistance on critical metal parts.
• Chemical Synthesis: Functions as a reagent or catalyst in organic synthesis and materials science research for developing novel compounds.
• Analytical Standards: Used to prepare calibration standards and reference materials for analytical techniques like ICP-MS and AAS to quantify rhenium content.

Quality Control

Our Perrhenate products undergo rigorous quality testing to ensure compliance with industry standards. We provide material with purity levels tailored to specific applications, from industrial catalyst precursors to high-purity research grades. Certificates of Analysis (COA) detailing assay, impurity profiles (e.g., by ICP-OES), and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and handling properties.
