Cold sintering of lead-free ferroelectric perovskites
Fabrication of electroceramics usually requires high sintering temperatures of 800 to 1400 °C, which can unintentionally lead to problems such as volatilization of species, formation of secondary phases and excessive grain growth. These problems can cause inhomogeneous microstructures, non-stoichiometric chemical compositions and limited material functionality. Therefore, there is a need …
