· Se8 Ta4

Se8Ta4 is an experimental selenium-tantalum compound belonging to the chalcogenide semiconductor family, combining a volatile chalcogen (selenium) with a refractory transition metal (tantalum) to create a mixed-composition material. This compound is primarily of research interest for exploring phase behavior, crystal structure, and electronic properties in the selenium-tantalum system rather than an established commercial product. Its potential applications lie in advanced semiconductors, thermal energy conversion, or specialized optoelectronic devices, though the material remains largely in the investigative stage; engineers considering this composition should treat it as a development-phase material requiring custom synthesis and characterization.

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.
