· K2ZnO2

K2ZnO2 is an inorganic ceramic compound belonging to the zinc oxide family, combining potassium and zinc oxides in a binary ceramic system. This material is primarily of research and development interest rather than a mature commercial product, investigated for applications requiring zinc oxide's semiconducting and photocatalytic properties combined with alkaline metal dopant effects. The compound is explored in emerging fields such as photocatalysis, optical coatings, and solid-state chemistry, where tailored electronic properties and thermal stability are critical; it represents the broader zinc oxide ceramic family's potential for engineered functional applications beyond traditional refractory or abrasive uses.
