This element is a grayish-white, lustrous, brittle metalloid. Although germanium is a poor conductor of electricity, it is often doped with other elements and is used as a transistor element in thousands of electronic applications. Germanium is most important as a semiconductor material and it is on this area that the majority of germanium is used.
