A new approach for obtaining ceramic NASICON (Na3Zr2Si2PO12) films sintered in situ by a sol–gel method, using spray deposition and near-infra red sintering.

In this work we demonstrate a NASICON film sintered in situ onto a fused silica substrate. This production method drastically reduces the manufacturing time by combining the use of a spray-coated sol–gel solution and near-infrared (NIR) ultrafast sintering technology. This is the first demonstration of NIR sintered ceramics at high temperatures (∼1000 °C). [ABSTRACT FROM AUTHOR]
