Nowadays various methods are presented for synthesis of barium strontium titanate (BST) nanopowders with different morphology and properties. Each of these (BST)s has got individual characterization that makes it suitable for a special application. Every method has a special quality, causes it to have preference over the other methods. Low processing temperature is a desired point which most of methods are aimed to reach. Below are some BST properties and fabrication routes summarized. X-ray diffractometer is used to investigate the characterization of synthesized BST and in some methods analysis of electron microscopy and Energy Dispersive X-Ray Spectroscopy are provided.
