Description

Palladium Hydride CAS NO 12648-42-9 is an intermetallic compound where hydrogen atoms occupy interstitial sites within the palladium metal lattice. This material is critical for applications requiring a reversible hydrogen storage medium or a hydrogen-selective membrane. It is essential for industries focused on hydrogen purification, catalysis, and advanced sensor technology, where controlled hydrogen absorption and desorption properties are paramount.

Application

• Hydrogen Purification & Separation Membranes: Used in dense metallic membranes for the high-purity separation of hydrogen from gas mixtures.
• Heterogeneous Catalysis: Serves as a catalyst or catalyst precursor in hydrogenation and dehydrogenation reactions.
• Hydrogen Storage: Acts as a reversible solid-state medium for hydrogen storage in energy systems.
• Gas Sensing: Employed in hydrogen leak detectors and sensors due to its electrical resistance change upon hydrogen absorption.
• Electrochemical Applications: Used in electrodes and components for fuel cells and electrolyzers.
• Research & Development: Fundamental material for studying metal-hydrogen interactions and phase behavior.

Quality Control

Our Palladium Hydride is manufactured and tested under stringent quality protocols. Each batch is characterized for critical parameters including hydrogen content, phase purity, and particle morphology to ensure consistent performance in demanding applications. Certificates of Analysis (COA) detailing lot-specific results are provided to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and hygroscopic (moisture-sensitive), this material must be stored under an inert gas (e.g., argon) in a cool, dry place. Recommended storage temperature is 15-25°C. The container should be kept sealed to minimize exposure to air and moisture.
