Arsenic

Arsenic (As) is a brittle, gray metalloid known for its semiconductor properties and its historical use in pesticides and wood preservatives. With a melting point of 817 °C and a notable toxicity, arsenic compounds are carefully handled in industrial and scientific applications. It exhibits multiple allotropes and several oxidation states, with the +3 and +5 states being most common. Arsenic’s unique electrical and chemical properties make it valuable in electronics, materials science, and environmental chemistry.

Goodfellow provides high-purity arsenic (As) tailored to meet the needs of specialized industries and research fields. One of its most notable uses is in the production of gallium arsenide (GaAs) semiconductors, which are widely employed in high-speed electronic devices such as mobile phones, satellite communications systems, and light-emitting diodes (LEDs). Arsenic compounds also play a role in the manufacturing of specialized glass used in optics and infrared technologies. Furthermore, arsenic is used as a doping agent in silicon-based electronics to enhance conductivity and performance. Beyond electronics, arsenic is being explored for its potential applications in advanced materials research, particularly in areas like quantum computing and optoelectronics. Its ability to form stable compounds opens up possibilities for creating innovative materials with tailored properties. Goodfellow’s arsenic products support groundbreaking research into next-generation electronic devices while contributing to advancements in optical technologies.
