About Us
We produce high-purity arsenic. This is mainly used for semiconductor and optoelectronic applications. We have more than 70 years of experience in the production of high-purity arsenic and other high-purity metals. Our production facilities are located in Saxony-Anhalt, in the city of Osterwieck.
Interesting Facts About Arsenic
High-purity arsenic is required for the production of III/V semiconductors such as GaAs, which is used to
manufacture integrated circuits (power amplifiers in cell phones, in radar technology, in wireless
communication devices (IoT) etc.) and in the manufacture of LEDs and laser diodes. Special product forms of
metallic arsenic are suitable for use in MBE systems. Arsenic(III) chloride is required to produce organic
compounds used in MOCVD processes.
In everyday life, you will find our arsenic in your cell phones, your WiFi base station, in chargers, in IR
cameras and even in your car. The introduction of the 5G standard in particular is leading to an increasing
demand for our product. All of this is our contribution to building a modern society - from Germany for the
world.
