Investigation of mineralogical composition and technological properties of conventional brick clays

Abstract

in this research the layers of a Hungarian conventional brick clay deposit were examined both on material and mineralogical structures and compositions as well as on technological properties. During their examination the authors have found that the volumes of X-ray amorphous submicron and nano particles of the conventional brick clays do not influence on the dry sensitivity of the extruded and formed green products. the authors have found also a strong correlation between the X-ray amorphous nano particles of raw materials and the bending strengths of the sintered ceramics. As more the volumes of submicron and nano particles are in the conventional brick clays as higher are the bending strengths of the produced from them sintered ceramics.
