Abstract

The growth of NaTaO3 crystals through the reaction between NaNO3 and a Ta substrate was directly observed using in-situ laser microscopy and in-situ X-ray diffraction. Voids and creases were first produced at ∼430 °C and then NaTaO3 crystals grew at ∼440 °C in a moment. Because the NaTaO3 crystals had formed during heating, the driving force for crystal growth was concluded to be the evaporation of NaNO3.
