SYNTHESIS AND ANALYSIS OF Lao.9MnO3 BY COMBUSTION METHOD
AbstractThe Lao.9MnO3 has been synthesized from lanthanum acetylacetonate, manganese acetylacetonate and urea by combustion method at 800oC. The analysis of the synthesized Lao.9MnO3 show it to be a semi-conducting nanopolycrystalline material having orthorhombic geometry with unit-cell parameters: a = 5.50335Ao; b = 5.7250Ao; c = 7.70028Ao and with Mn4+ content of 12%. The mean-size of the particles of Lao.9MnO3 was obtained from TEM analysis at 80nm.
KEY WORDS: Lao.9MnO3, acetylacetonate, nanopolycrystalline, combuston method, semi-conductor.
