· JVASP-100276· K5Bi4

K5Bi4 is a bismuth-potassium ceramic compound representing a mixed-metal oxide or intermetallic ceramic phase. As a potassium-bismuth composite, this material falls within the family of functional ceramics studied for electrochemical, thermal, or photocatalytic applications, though it remains primarily a research compound without widespread commercial production. The bismuth-containing ceramic family is of interest in solid-state chemistry for ion conductivity, catalytic properties, and potential photovoltaic or radiation-shielding applications depending on the specific crystal structure and phase composition.

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.
