· JVASP-90674· K

Potassium (K) is a soft, highly reactive alkali metal notable for its low density and high chemical reactivity with moisture and oxygen. While rarely used as a structural material in its pure form due to these reactivity constraints, potassium finds specialized industrial applications in heat transfer systems, organic synthesis, and as a reducing agent in metallurgical processes. Engineers select potassium primarily for thermal management in liquid-metal cooling systems and in chemical manufacturing where its reactivity is an asset rather than a liability.

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.
