Product Description
Indium Granules (In) | ≥99.99% Purity
FrankLab High-Purity Metal Materials Series
Product Overview
FrankLab Indium Granules are manufactured from ultra-high-purity indium metal (≥99.99%), featuring excellent chemical purity, uniform granule morphology, and outstanding ductility. Compared with indium sheets or wires, granules provide superior weighing accuracy, melting convenience, and compositional control, making them ideal for laboratory research, alloy preparation, and advanced electronic materials.
Each batch is produced with strict control over contamination and is suitable for research-grade and pilot-scale applications.
Key Features
•Ultra-High Purity: ≥99.99% (4N), trace impurities tightly controlled
•Granular Form: Easy to weigh, mix, melt, and dose
•Excellent Ductility & Low Melting Point: ~156.6 °C
•High Chemical Stability: Suitable for vacuum and inert-atmosphere processes
•Batch Consistency: Reliable reproducibility for research and production
