PPM Pure Metals

Antimony High purity Antimony is used to produce III/V-semiconductors like Indium Antimonide (InSb) used for Hall sensors and infrared detectors and as a dopant for [...]

Germanium Germanium is transparent for infrared radiation that is that has a wavelength of between 2 and 12 micrometers. It is therefore ideal to produce IR-optical devices [...]

Arsenic High purity Arsenic is needed to produce III/V-semiconductors like GaAs, which is used to make high frequency integrated circuits (power amplifiers in cell phones, [...]
