| Resumo: | The clay mineral attapulgite is a group of hormitas, which has its
structures formed by microchannels, which give superior technological
properties classified the industrial clays, clays of this group has a very versatile
range of applications, ranging from the drilling fluid for wells oil has applications
in the pharmaceutical industry. Such properties can be improved by activating
acid and / or thermal activation. The attapulgite when activated can improve by
up to 5-8 times some of its properties. The clay was characterized by X-ray
diffraction, fluorescence, thermogravimetric analysis, differential thermal
analysis, scanning electron microscopy and transmission electron microscopy
before and after chemical activation. It can be seen through the results the
efficiency of chemical treatment, which modified the clay without damaging its
structure, as well as production of polymer matrix composites with particles
