K4O10W4
K4O10W4 is a semiconducting potassium tungsten oxide that exists in a metastable state.
About K4O10W4
K4O10W4 is a semiconducting inorganic compound composed of potassium, oxygen, and tungsten. Its electronic structure suggests potential utility in specialized optoelectronic or sensing applications where specific semiconducting properties are required.
While this material exhibits a complex structural profile with multiple reported configurations, it is characterized by thermodynamic instability relative to its elemental components. This suggests that synthesis requires precise control over environmental conditions to stabilize the lattice.
Key Properties
