· JVASP-111053· GeTe5Pb4

GeTe5Pb4 is a chalcogenide ceramic compound based on germanium telluride with lead doping, belonging to the family of phase-change materials and semiconductor ceramics. This material is primarily of research interest for thermal energy storage, non-volatile memory applications, and advanced optoelectronic devices where its tunable crystalline-to-amorphous transitions can be exploited; it represents an emerging alternative to traditional phase-change materials like GeSbTe, potentially offering improved thermal stability or switching performance for next-generation memory and thermal management systems.

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.
