info

Semiconductors

Arsenic is a critical n-type dopant for silicon-based semiconductors and a primary component in III-V compound semiconductors such as Gallium Arsenide (GaAs).

info

Alloying

Used as an alloying agent to strengthen lead-acid battery grids and improve the properties of copper and brass alloys.

info

Sputtering

High-purity arsenic is used to manufacture sputtering targets for the deposition of thin films in microelectronic and optoelectronic device fabrication.

info

Optoelectronics

Essential for the production of laser diodes, LEDs, and infrared optics through the formation of compounds like GaAs and InAs.
