High-Purity Magnesium Metal Granules & Chips | Technical Sourcing Guide
Magnesium Metal Granules (also supplied as high-purity magnesium chips) are alkaline earth metal particles produced via vacuum distillation and mechanical processing. They offer high chemical reactivity and a favorable strength-to-weight ratio, serving as an essential raw material for metallurgical reduction, chemical synthesis, and alloy manufacturing.
Key Features
High chemical reactivity ensuring rapid reaction kinetics for synthesis pathways (e.g., Grignard reactions).
Controlled particle size distribution designed to minimize dust and fine particle loss.
Low trace impurity profile (specifically Fe, Ni, and Cu) to prevent secondary contamination in alloy systems.
Stable surface passivation to mitigate premature oxidation during long-term storage.

FAQ
Q: How are the granules protected against moisture during transit and storage?
A: They are packed in hermetically sealed iron drums or moisture-barrier FIBC bags containing desiccant pouches inside an inert gas atmosphere.
Q: Can particle size distribution be customized for specific reaction rates?
A: Yes. Mechanical screening parameters can be adjusted to specific mesh cuts based on your process requirements.
Q: Is third-party inspection supported prior to dispatch?
A: Yes, pre-shipment inspections by independent agencies such as SGS or BV are fully accepted.
