Product Overview
Nickel(II) sulfate hydrate in Puratronic™ grade delivers exceptional 99.9985% purity (metals basis), making it indispensable for applications demanding ultra-low trace metal contamination. This crystalline hydrate form ensures consistent solubility and reactivity in aqueous systems, critical for electrochemical processes like nickel plating or as a precursor in battery cathode materials. The high-purity profile minimizes interference in analytical techniques such as ICP-MS or AAS, where even ppb-level impurities can skew results. Its controlled hydration state provides stability during storage while maintaining precise stoichiometry for synthesis reactions. The material’s low iron, copper, and cobalt content (<10 ppm combined) prevents catalytic poisoning in hydrogenation or cross-coupling reactions. Unlike technical-grade alternatives, this Puratronic™ variant undergoes rigorous multi-stage purification, including zone refining and sublimation, to eliminate volatile and non-volatile impurities. The powder’s uniform particle size distribution (D50 ~15 µm) enhances dissolution kinetics without requiring prolonged stirring. Compatible with most inorganic acids and bases, it serves as a reliable nickel source for preparing standard solutions or doping semiconductor materials. Store under inert gas in a desiccator to preserve its hydrate structure and prevent oxidation.
FAQs
1. What is the difference between Puratronic™ and standard-grade nickel sulfate?
Puratronic™ grade undergoes additional purification steps like sublimation and electrochemical refining to achieve 99.9985% metals basis purity, whereas standard grades typically range between 98-99.5% with higher trace metal contaminants like iron or chromium.
2. Can this be used directly for electroplating baths without further purification?
Yes, the 99.9985% purity eliminates the need for pre-treatment in most electroplating applications, though you may still filter the solution to remove any particulate matter from handling.
3. How does the hydrate form affect its solubility compared to anhydrous nickel sulfate?
The hydrate form dissolves more readily in water at room temperature (solubility ~29.3 g/100 mL) compared to anhydrous nickel sulfate, which requires heating for complete dissolution due to its higher lattice energy.
4. What precautions should be taken when storing this product long-term?
Store in a tightly sealed container under argon or nitrogen in a desiccator to prevent moisture absorption or oxidation. Avoid exposure to reducing agents or sulfur-containing compounds, which can form insoluble nickel sulfides.
5. Is this compatible with PTFE or glass labware during handling?
Yes, it is fully compatible with both PTFE and borosilicate glass. For trace analysis, use PTFE-coated tools to avoid metal leaching from glassware at extreme pH conditions.
