Arsenic

Arsenic (CAS 7440-38-2 ) is a metalloid element sourced for industrial and specialty applications where controlled introduction of element 33 into alloys, semiconductors, or catalytic systems is required. It functions as a dopant, alloying agent, and catalyst component across electronics manufacturing and metallurgical processing. In semiconductor fabrication, it is used as an n-type dopant to modify electrical conductivity. This process directly influences device performance in transistors and diodes by modifying silicon and germanium wafers. The metallurgical industry incorporates it into lead and copper alloys to improve hardness. These enhancements are critical for high-temperature strength in battery grids and ammunition. In compound semiconductor production, it is a primary feedstock for gallium arsenide wafers used in high-frequency devices. Optoelectronic devices also rely on this material for efficient operation. Certain heterogeneous catalytic processes employ arsenic-containing compounds derived from elemental arsenic as precursor material for chemical synthesis. The product is supplied as a solid in lump, shot, or powder form, with purity grades ranging from technical to high-purity for electronics-grade applications. Standard commercial grades are available for metallurgical use. Semiconductor and compound semiconductor manufacturers typically require certified high-purity material. These materials must meet tightly controlled trace metal specifications to ensure consistent performance in sensitive electronic components. Contact us for supply of Arsenic Request Quote
