· K2 Na4 B2 O6

K2Na4B2O6 is an alkali borate ceramic compound belonging to the borosilicate and borate mineral family, characterized by a mixed-alkali composition that influences its glass-forming and semiconducting properties. This material is primarily of research interest for applications in optical and electronic ceramics, where the alkali borate system is explored for non-linear optical devices, solid-state electrolytes, and specialized glass compositions. The mixed potassium-sodium formulation makes it notable for tuning thermal expansion and ionic conductivity compared to single-alkali borate systems, though industrial adoption remains limited to specialized research and developmental applications rather than high-volume production.

Export Control

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.
