Facile In Situ Formation of Potassium Sodium Niobate (KNN) Using The Hexaniobate Polyoxometalate
Chemistry – A European Journal, Volume 31, Issue 12, February 25, 2025.Lead‐based piezoceramics are the dominant materials used in electronic devices, despite the known toxicity of lead. Developing safer piezoelectric materials has inspired the pursuit of lead‐free piezoceramics, however some challenges remain in accessing these materials reproducibly.
