Abstract

Nanocrystalline strontium zirconate has been synthesized using a modified reverse micellar route (avoiding Sr-alkoxide). Powder X-ray diffraction studies show the monophasic nature of the powder of SrZrO3 after heating at 800 °C. The particle size has been obtained from X-ray line broadening studies (not, vert, similar62 nm) and transmission electron microscopic studies (not, vert, similar72 nm). The average grain size of 85 nm was found to be reasonably stable to sintering till 1000 °C. A dielectric constant of 19.8 is observed for nanocrystalline SrZrO3 sintered at 1000 °C. Detailed dielectric studies have been carried out with respect to frequency and temperature.
