Determination of poly morphological transitions of dendrites on natural magnesite surfaces

Abstract

Manganese dendrites on the magnesite ore are natural solid phase and poly morphological structures of manganese oxides (MnO2+, 3+- 4+). They are a wide variety of structures.In this study, radial particle distribution and growth critical exponents are investigated by using the scaling method for natural manganese dendrites.For this purpose, the samples are grouped according to the superficial heterogeneity of the deposits and the calculations are made. The results of radial particle distributions are similar to the Gaussian distribution approach. We have performed the radial growth distribution function to test this hypothesis.The obtained data are fitted to thenon-regression method as the Gaussian function and determined their both median and the median diameter for the manganese dendrites that have various solid morphological transitions. Also, growth critical exponent values vary between 0.424 ≤ α ≤ 0.732 and 2.153 ≤ β ≤ 10.457 by using linear regression method. The results were compared with the real and simulated representation values in the literature.
