· K1 Nb1 O3

KNbO₃ (potassium niobate) is a perovskite oxide semiconductor belonging to the family of functional ceramics with ferroelectric and piezoelectric properties. This material is primarily investigated in research and emerging applications for electro-optic modulators, nonlinear optical devices, and integrated photonics, where its crystal structure enables efficient light manipulation and frequency conversion. KNbO₃ is valued over some alternatives because of its relatively high nonlinear optical coefficients and transparency across visible and near-infrared wavelengths, making it a candidate for advanced optical communication systems, quantum photonics, and precision sensing applications.

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.
