La microscopía electrónica aplicada a la observación de las alteraciones en algunos minerales de la arcilla

espanolEn el presente trabajo se hace un estudio por microscopia electronica de los residuos solidos procedentes de las arcillas sometidas a los tratamientos con agua oxigenada y asimismo de aquellas a las que posteriormente se les extrajo geles. Se observan las alteraciones sufridas por los minerales, las cuales estan relacionadas directamente con el numero de tratamientos efectuados, teniendo a su vez gran influencia el grado de perfeccion de los cristales de los distintos minerales. EnglishThe solid residues from clays which have been submitted to treatment with hydrogen peroxide have been studied by electron microscopy. Samples which had been cleared from gels after the H2O2 treatment have also been studied. The alterations shown by the minerals were easily observed and were directly related to the number of treatments performed. These alterations were also related to the degree of crystalline perfection of the different minerals present in the clay samples.
