Reaction of Ammonia with Graphite-Potassium Compounds

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1994
Reaction of ammonia vapor with a KC 8 GIC and treatment (vacuum and heating) produces a new second stage GIC: K(NH 3 ) 0.5 C 8 with di=815 pm. The stage 1 GIC can be obtained by reaction with potassium vapor. Similar treatment with KC 24 leads to a stage 2 GIC:K(NH 3 ) 1.3 C 24 with a smaller di=648 pm.

Facile Fabrication of Nitrogen‐Doped Porous Carbon as Superior Anode Material for Potassium‐Ion Batteries

Advanced Energy Materials, 2018
Potassium‐ion batteries (PIBs), using carbon materials as the anode, are regarded as a promising alternative to lithium‐ion batteries owing to the feasible formation of stage‐1 potassium intercalation compounds (KC8).

Unusual Chemical Behavior for Potassium under Pressure:  Potassium−Silver Compounds

Journal of the American Chemical Society, 1996
At high pressures, there are large changes in the size and electron concentration of the alkali metals. As a result, significant changes should occur in the solid-state chemistry of these elements, allowing the formation of alkali metal−transition metal compounds. The formation of two alkali metal−transition metal compounds, K3Ag and K2Ag, is reported.
