Product Description
Specifications

Product Overview

Germanium granules are light gray metallic particles with exceptional semiconductor properties, widely used in high-tech applications. With a melting point of 937°C, a boiling point of 2830°C, and a density of 5.35 g/cm³, they offer high stability and excellent optical performance. Their diamond-like crystal structure makes them hard yet brittle, and their chemical stability ensures usability in demanding environments. Germanium granules are insoluble in water but soluble in aqua regia, concentrated nitric acid, or sulfuric acid.
