We studied the thermal stability and many-sided properties of Y 0 .5 Sr 0 .5 Cr 0 .5 Mn 0 .5 O 3 chromite-manganite that was made using the sol-gel method.We focused on the syngony type, unit cell parameters, and x-ray analysis.To conirm the results of the chromite-manganite indexing, the inverse values of the squares of interplane distances (104/d2) and the consistency of the x-ray and pycnometric densities were found to be very close to each other.It was found that the synthesised chromite-manganite crystallises in orthorhombic syngony and has a perovskite-like structure.Scanning Electron Microscopy (SEM) shows that chromite-manganite is uniformly distributed, and the crystallites are sized between 6 and 20 microns.The analysis of the relationship between heat capacity and temperature using the Thermo Gravimetry Analysis (TGA) technique demonstrates the stability of the internal structure and the presence of polymorphic transformations in the sample under study.
