摘要：

Single phasic nanocrystalfine CaZrO3 powder has been synthesized by glycine nitrate solution combustion method around 300 degrees C using nitrate as oxidant and glycine as fuel. The as prepared product obtained as a result of combustion itself is crystalline and nearly single phasic CaZrO3 confirmed by X-ray diffraction (XRD). The product calcined at 600 degrees C reveals carbonate free single phasic orthorhombic structured CaZrO3. To study the impact of oxidant to fuel ratio (O/F) and ignition temperature, a systematic variation of O/F and ignition temperature of combustion reaction has been investigated by analyzing the products through XRD in each case. These products have been characterized by XRD, Fourier Transform Raman spectroscopy, Thermal Analysis (TGA/DTA), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). Raman Spectrum reveals single phasic nanocrystalline perovskite CaZrO3. Spherical shaped particles were observed through SEM. TEM results also confirm the particles to be in nano regime (30-90 nm).
