Flame Inhibition by Potassium-Containing Compounds
Combustion Science and Technology, 2017A kinetic model of inhibition by the potassium-containing compound potassium bicarbonate is suggested. The model is based on the previous work concerning kinetic studies of suppression of secondary flashes, inhibition by alkali metals and the emission of sulfates and chlorides during biomass combustion.

Tailor-made Oligosilyl Potassium Compounds
Organometallics, 2002A number of differently substituted oligosilyl potassium compounds have been prepared by reaction of the respective trimethylsilylated precursors with potassium tert-butoxide. It has been demonstrated that in the presence of larger trialkylsilyl groups always trimethylsilyl groups are removed selectively.

The stability of potassium-graphite deintercalation compounds
Carbon, 1996We have synthesized K-GICs (potassium-graphite intercalation compounds) by the modified two-bulb method. The compounds were kept under a stabilization agent (liquid paraffin). The stage transition of K-GDICs (graphite deintercalation compounds), owing to the slow diffusion of water, was observed by X-ray diffraction measurements.

Superconductivity in graphite–potassium intercalation compounds
Journal of Chemical Physics, 1980Superconductivity transitions were studied in golden graphite−potassium compounds. The transition temperature changes were studied by adding hydrogen to the compound. (AIP)

Potassium-oxygen graphite intercalation compounds
Synthetic Metals, 1994Abstract Intercalation of potassium superoxide KO 2 into graphite in the presence of potassium metal was studied. Graphite intercalation compounds of stage 1 (assigned formula C 4 KO 2 , c -axis repeat distance 8.44 A) and stage 2 (assigned formula C 8 KO 2 , c -axis repeat distance 11.75 A) were synthesized and isolated for the first time.

Unusual Chemical Behavior for Potassium under Pressure: Potassium−Silver Compounds
Journal of the American Chemical Society, 1996At 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.

ESR dosimetry with lithium, potassium, and sodium compounds
Applied Radiation and Isotopes, 2022This work consists of a first investigation of materials that could be used as ESR dosimeters with doses up to 5 Gy aiming possible applications that would include retrospective dosimetry or dosimetry in specific applications. The characteristics considered were radiological properties close to that of soft tissues, evaluated through their effective ...

Polyanionic Compounds for Potassium‐Ion Batteries
The Chemical Record, 2018AbstractLithium‐ion batteries have the highest energy density among practical secondary batteries and are widely used for electronic devices, electric vehicles, and even stationary energy‐storage systems. Along with the expansion of demand and applications, the concern about resources of lithium and cobalt is growing.
