Quality Control

Our Gadolinium-Silicon-Germanium Alloy is produced and handled under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot is characterized for its specific composition (Gd:Si:Ge ratio), phase purity, and magnetic transition temperature. A comprehensive Certificate of Analysis (COA) is provided, detailing results from techniques such as X-ray diffraction (XRD), inductively coupled plasma (ICP) analysis, and magnetic property measurement system (MPMS) testing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C) under an inert atmosphere (e.g., argon) to prevent surface oxidation. This material is moisture-sensitive (hygroscopic) and should be handled in a controlled, dry environment.
