Product Overview
Palladium(II) oxide (PdO) with 99.995% purity (trace metal basis) is a high-performance inorganic compound designed for demanding laboratory applications where trace impurities can compromise results. This black, crystalline powder exhibits exceptional thermal stability up to 875°C, making it ideal for high-temperature catalytic processes and sensor development. The ultra-high purity grade ensures minimal interference from metallic contaminants, which is critical for analytical chemistry, materials science, and nanotechnology research. Its unique electronic properties and redox behavior enable precise control in catalytic reactions, particularly in hydrogenation and dehydrogenation processes. The powder form allows for easy dispersion in various matrices or direct use in solid-state applications. Unlike lower-grade alternatives, this trace-metal-basis PdO undergoes rigorous purification to eliminate residual platinum-group metals and other impurities, ensuring consistent performance in sensitive applications. The material’s stoichiometric composition and controlled particle size distribution further enhance its reliability in research settings where reproducibility is paramount.
FAQs
1. What is the difference between 99.9% and 99.995% palladium(II) oxide?
The 99.995% grade undergoes additional purification steps to remove trace metallic impurities (typically <50 ppm total) that could interfere with catalytic activity or analytical measurements. This makes it suitable for applications requiring ultra-high purity, such as semiconductor research or high-precision sensors.
2. Can this palladium(II) oxide be used directly in hydrogenation reactions?
While PdO is a precursor for catalytic applications, it typically requires reduction to metallic palladium (Pd°) for active hydrogenation catalysis. The oxide form can be converted via thermal treatment under hydrogen atmosphere or chemical reduction methods.
3. What storage conditions are recommended to maintain the product’s purity?
Store in a tightly sealed container under inert gas (argon/nitrogen) at room temperature. Avoid exposure to moisture or reducing agents, as PdO can gradually convert to metallic palladium in humid or reductive environments, altering its properties.
4. Is this product compatible with standard laboratory glassware?
Yes, but prolonged contact with borosilicate glass at high temperatures (>500°C) may cause slight contamination from alkali metals leaching from the glass. For ultra-high-purity applications, consider using quartz or platinum crucibles.
5. How does the particle size distribution affect performance in catalytic applications?
Smaller particle sizes (sub-micron range) provide higher surface area, enhancing catalytic activity but may require additional stabilization. This product’s controlled particle size distribution balances reactivity with handling ease for most research applications.
