Resumo
This work has for objective to evaluate the red ceramic processing obtained by mixing proper ceramic bodies for some types of products through the control of the particle size of their natural constituents. Four composites were elaborated with compositions varying in particle size of “clay fraction”, silt and sand located in different regions of the Winkler diagram. Specimens formed by uniaxial pressing were fired at 1000ºC. The composites were submitted to the following technological tests: water absorption, fired shrinkage and mechanical strength. The results showed that the elaborated composite with higher amount of “clay fraction” presented the best technological properties evaluated. This is attributed to the fine particle size of the “clay fraction” that promotes an efficient sintering process.
