· O4 K4

O4 K4 is a semiconductor material with an unspecified composition, likely referring to a binary or ternary compound within the oxide-potassium or chalcogenide-potassium material family. Without confirmed composition data, this appears to be either a research compound or a material designation requiring clarification in the source database. If part of the potassium oxide (K₂O) or potassium-based semiconductor family, it would be of interest in solid-state electronics, ion-conducting materials, or specialized optoelectronic applications where alkaline-metal compounds offer unique optical or electrical properties.

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.
