· K1 Na1 B2 H8

K1Na1B2H8 is an ionic borohydride ceramic compound containing potassium, sodium, boron, and hydrogen. This material belongs to the complex hydride family and is primarily of research interest for energy storage and hydrogen-related applications rather than established commercial use. The compound represents an experimental system being investigated for solid-state hydrogen storage, battery electrolytes, and thermal energy applications, where its mixed-alkali composition may offer tunable properties compared to single-metal borohydride alternatives.

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.
