Product Description

Characteristic

Germanium‘s atomic number 32, which atom has a radius of 122.5 pm. Under standard conditions germanium is a brittle,
silvery-white, semi-metallic element. This form constitutes an allotrope technically known as α-germanium, which has a metallic luster and a diamond cubic crystal structure, the same as diamond.
