Mineral Constituents of a Clay from Campos dos Goytacazes, Brazil

Abstract:

Article Preview

The mineral constituents of a typical clay from Campos dos Goytacazes, Brazil, were investigated in terms of their nature and morphology by analytical methods including transmission electron microscopy and energy dispersive spectroscopy. The clay was found to have a large amount of finer, < 2 μm, aluminumsilicate particles of kaolinite and, in smaller proportion, halloysite, which is also an aluminumsilicate. At 1050oC the clay shows a consolidated structure with continuous glassy matrix in which Ti, Fe and Si oxides as well as mullite crystals are thoroughly embedded.
