Potassium, Disk, 99.9%, 14 mm dia. x 0.45 mm th.

Potassium is alloyed with sodium (NaK) to create a liquid metal eutectic used as a high-efficiency heat transfer medium in nuclear reactors and specialized chemical cooling systems.

Potassium compounds and metal precursors are utilized in the development of advanced electrolyte systems for next-generation alkali-metal batteries to improve ionic conductivity.
