Germanium
(Ge) |
 Germanium is a grayish-white metalloid which is brittle and crystalline. Electrically it behaves as a semiconductor. Its chemistry is similar to that of silicon, and it has applications as an alternative to silicon as a basis for solid state electronic devices.
As a usually thin film material, Germanium
targets are used more and more widely. The shape
includes disk, sheet, tube, step, taper and so on. Also we can make some hole and
screw on the target base on your require. The surface is very beautiful.
They are used in widely optics , electron ,decorate, and so on.
Germanium
is a usually metal, It was used widely in I.R. optical , electronical, decorative
...field.
