· JVASP-50442· K2Sr2O3

K2Sr2O3 is an alkaline-earth oxide ceramic compound composed of potassium, strontium, and oxygen. This material is primarily of research and developmental interest rather than an established commercial product, positioned within the family of mixed-metal oxides that show potential for solid-state applications. The material may be explored for applications requiring specific ionic conductivity, thermal stability, or catalytic properties characteristic of strontium-containing ceramic systems.
