· JVASP-102947· KRbAu2

KRbAu2 is an intermetallic compound combining potassium, rubidium, and gold in a stoichiometric ratio. This is an experimental research material rather than an established engineering alloy; it belongs to the family of ternary alkali-gold intermetallics being studied for fundamental properties and potential advanced applications. The compound's notable characteristics include relatively low stiffness combined with unusual elastic properties (reflected in its Poisson's ratio), making it of interest to researchers investigating novel metallic phases, phonon engineering, or thermoelectric and electronic device concepts.

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.
