· KRbO3

KRbO₃ is a mixed-cation perovskite oxide compound composed of potassium, rubidium, and oxygen, belonging to the class of functional ceramic semiconductors. This material is primarily of research interest rather than established industrial use, being investigated for its potential in solid-state ionics, ferroelectric applications, and photovoltaic devices, where the dual alkali-metal cation composition may offer tunable electronic and ionic transport properties compared to single-cation perovskites.

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.
