Study of morphology of-PbO2 and determination of elementary cell constants

S.A.A.Sajadi

A laboratory prepared compound lead oxide -PbO2 was used for XRD and electron microscopic investigation. Using B.E.T. Method, the measurement of the particle size turned out to be 2.40 m2/g.Aseries of calculations was made to refine the cell constants. Then a frequently-used computer program (LSUCRIPC) was run to compute the cell constants more precisely.The received valueswere a=4.95048, b=5.93631, c=5.47491.
