· JVASP-127382· Ge7As

Ge7As is a germanium-arsenic ceramic compound belonging to the chalcogenide glass family, a class of materials formed from Group IV and Group V elements. This composition sits within the germanium-arsenic system that has been extensively studied for infrared optical applications and solid-state electronics due to its unique glass-forming properties and semiconductor characteristics. Ge7As compounds are primarily of research and specialized industrial interest rather than commodity materials, valued in optics, photonics, and potentially in advanced semiconductor devices where their infrared transmission and electronic properties offer advantages over conventional materials.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
