| Abstract | The present invention provides a novel process for preparing perovskite catalysts by reactive grinding using an improved planetary ball mill designed and fabricated indigenously as disclosed in our patent application number 2521/MUM/2013. The present invention provides a novel process for preparing perovskite wherein the mixture of said salt precursor or oxide mixed in stoichiometric ratio and the Stainless Steel Balls (2F) are loaded into said Jar (2A) of said Improved Planetary Ball Mill (1) and the said Jar (2A) is closed with the Jar Cover (2B) with Lock (2C) and O-ring (2D) and are intensely milled with speed of revolution of said Sun Wheel (3A) at 200 rpm in anti clock wise direction and the speed of rotation of said Jars (2A) at 350 rpm in clock wise direction for 5 to15 h. |
