· JVASP-102619· Ge2Bi2Te5

Ge2Bi2Te5 is a quaternary chalcogenide ceramic compound belonging to the telluride family, combining germanium, bismuth, and tellurium in a layered crystal structure. This material is primarily investigated for phase-change memory (PCM) applications and thermoelectric devices, where its ability to rapidly switch between crystalline and amorphous states enables non-volatile data storage, and its moderate thermoelectric properties support solid-state cooling and power generation. While not yet widely commercialized compared to established alternatives like GST (Ge-Sb-Te), this compound represents an active research area for next-generation memory technologies and energy conversion systems where improved thermal stability and switching speed are critical.

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.
