Nano crystalline ceramic LaZrYBaCa2Cu3O11 is prepared by the solid state reaction method. The process is mechanically done by high energy ball milling. The mixed powder is synthesised and calcined in a specially designed high temperature furnace. The pure material prepared is then calcined in ambient air and optimum temperature so that the desired homogeneity and phase formation is acquired. Using TGA, DTA and DSC thermal behaviour of the sample at a high temperature is studied. EDX analysis is done to find out the elemental composition.
