Abstract

The goal of the present work is to determine the viability of the use of specific (rhyolitic) rocks milled by dry attrition as a substitute for traditional materials, such as quartz or feldspar, to obtain gres ceramic by single firing. We evaluated different formulations using a white clay used in the Argentine industry, namely Tinkar Z, with well-defined chemical composition, and using a wet conformation. First we evaluated the behavior of clay by itself, and later we evaluated well-defined mixtures by means of representative tests on ceramics such as raw plasticity, rate of wall drying, densification, contraction, porosity and absorption as a function of thermal treatment.
