· KScO2

KScO2 is a potassium scandium oxide ceramic compound, representing a mixed-metal oxide system that combines alkali and rare-earth elements. This material is primarily of research and development interest rather than established commercial use, with potential applications in solid-state ionics, thermal management, and advanced ceramic systems where the combined properties of potassium and scandium oxides may offer unique thermal, electrical, or structural characteristics not available in single-component ceramics.

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.
