· JVASP-141678· KCaH3

KCaH3 is an experimental complex metal hydride ceramic composed of potassium, calcium, and hydrogen. This material belongs to the family of alkaline earth hydrides and represents an emerging research area in hydrogen storage and solid-state chemistry, with potential applications in energy storage systems where high hydrogen density and thermal stability are critical. While not yet commercialized for mainstream engineering applications, KCaH3 is investigated primarily in research laboratories for hydrogen storage media and advanced fuel cell technologies, where its ability to reversibly store and release hydrogen under controlled conditions offers advantages over traditional storage methods.

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.
