· JVASP-71163· KNaBe2

KNaBe2 is a potassium-sodium beryllium ceramic compound, likely a beryllate phase developed for specialized applications requiring low-density ceramic materials. This composition falls within the family of alkali-beryllium oxides, which are primarily of research and industrial interest for applications demanding lightweight, thermally stable ceramic matrices or optical/functional ceramic components. The material's low density distinguishes it from conventional technical ceramics and makes it relevant for weight-critical aerospace and high-temperature composite applications, though its beryllium content imposes significant health and environmental handling constraints that limit broader industrial adoption.

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.
