Product Overview

This ultra-pure 99.999% zinc oxide (trace metal basis) is engineered for demanding laboratory applications where minimal impurities are critical. The fine white powder form ensures uniform dispersion and consistent reactivity in experimental setups. Its exceptional chemical stability makes it ideal for applications requiring high thermal and electrical conductivity properties. The trace metal basis certification guarantees that residual metallic contaminants are reduced to parts-per-million levels, eliminating interference in sensitive analytical procedures. The material’s high surface area-to-volume ratio enhances its catalytic efficiency in chemical reactions. Its non-hygroscopic nature ensures long-term storage stability without degradation. The product undergoes rigorous quality control to maintain batch-to-batch consistency, with each lot accompanied by comprehensive certification documentation. The 99.999% purity level exceeds standard reagent-grade specifications, making it particularly valuable for semiconductor research and advanced materials synthesis where trace impurities can significantly impact results.

FAQs

1. What is the particle size distribution of this zinc oxide powder?

The powder typically features a sub-micron particle size distribution with an average particle diameter in the 0.1-0.5 micron range, though exact specifications may vary slightly between production batches. This fine particle size contributes to its high surface area and reactivity in laboratory applications.

2. Is this zinc oxide compatible with organic solvents?

While zinc oxide is generally insoluble in most organic solvents, it can be dispersed in certain polar solvents like ethanol or acetone with proper mixing techniques. The dispersion stability depends on the specific solvent system and any surfactants used in the preparation.

3. What alternatives exist for applications requiring slightly lower purity levels?

For applications where 99.999% purity isn’t essential, 99.9% or 99.5% purity zinc oxide grades are commonly available. These lower purity grades often provide sufficient performance at a reduced cost for many standard laboratory procedures.

4. How should this high-purity zinc oxide be stored for long-term use?

Store in a tightly sealed container in a cool, dry environment away from direct sunlight and moisture. While the material is stable under normal conditions, exposure to humid environments over extended periods may lead to slight surface hydration.

5. What quality documentation accompanies this product?

Each batch is supplied with a comprehensive Certificate of Analysis detailing the trace metal impurities, particle size distribution, and other relevant physical-chemical properties. Additional documentation including safety data sheets is also provided with each shipment.
