Growth and Characterization of LaMnO3 Crystals

S. Kumararaman and T. Thaila

The crystals of LaMnO3 have been grown by single diffusion method in gel growth. The grown crystals have been analyzed by different characterization techniques. X-ray diffraction studies shows that it belongs to Perovskite crystal system having the lattice dimensions a= 5.582Å, b= 5.515Å and c= 7.763Å. The mechanical properties of grown crystals have been studied by using Vickers Microhardness tester. The surface defects were examined by adopting etching technique.
