KNaH2
ceramic· JVASP-36118· KNaH2
KNaH₂ is an experimental ionic hydride ceramic composed of potassium, sodium, and hydrogen atoms, representing an emerging class of materials in solid-state chemistry research. This compound belongs to the family of metal hydrides and mixed-alkali hydrides, which are being investigated for energy storage, hydrogen sorption, and solid-state ionic conductor applications. While not yet established in mainstream industrial production, materials in this family show promise for next-generation energy storage systems and hydrogen economy technologies due to their potential for reversible hydrogen uptake and ionic conductivity at moderate temperatures.

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.
