KMg6NaO7
KMg6NaO7 is a complex, semiconducting quaternary oxide that exists in a metastable state.
About KMg6NaO7
KMg6NaO7 is a multicomponent oxide featuring a combination of potassium, magnesium, and sodium cations. As a semiconducting material, it represents an interesting case study in complex oxide synthesis where multiple metal centers are integrated into a single crystalline framework.
Despite its existence in multiple structural configurations across various databases, the compound is characterized as being thermodynamically metastable. This positioning above the hull suggests that while it can be synthesized, it remains a challenging target for traditional solid-state processing compared to more stable, naturally occurring mineral phases.
Key Properties
