Germanium Metal - Ge Lumpy Ingot - 99.999% Pure - 100g

Description

Discover the world of germanium with our high-purity 99.999% (5N) germanium metal ingot.

Germanium is a lustrous, brittle, greyish-white metalloid that played a foundational role in the electronics revolution - the first transistor was built using germanium in 1948. Today it remains a critical material in advanced optics and semiconductor technology.

This germanium ingot is perfect for collectors, hobbyists, researchers, and science enthusiasts alike. Germanium has a density of 5.32 g/cm³ and a high melting point of 937.4°C, making it a solid, hard, and visually striking element to add to any collection.

Your germanium ingot will arrive in solid form with a characteristic metallic lustre. Store in a dry environment - germanium is stable in air at room temperature.
