摘要

Thermal changes occurred during firing of clays in order to obtain ceramic samples are important for understanding their properties. In the present paper we report results obtained by thermogravimetric (TGA) and differential thermal analysis (DTA) as well as by X- ray diffraction (XRD) on row and high temperature heat treated clay samples used to produce black-ceramic. TGA and DTA data point out characteristic dehydroxylation and decomposition reactions, and only slight structural changes in the crystalline network up to 700 ℃. For the samples heat treated 1100 ℃ and 1200 ℃, the XRD results show the development of magnetite and/or maghemite crystalline phase.
