Abstract:
The mechanical strength, color, porosity and shrinkage are crucial for assessing the quality of the final ceramic. In our study, a performance evaluation after firing, as well as semi-quantitative chemical analysis of two samples of sedimentary kaolin, a known sample A, from a mining area located Ipixuna-PA, and another called sample B showing staining pink, derived from outcrops roadblock in Paragominas-PA in order to characterize ceramics obtained from such clays. For each kaolin sample we made test specimens which underwent three sintering temperatures: 1050 °, 1150 ° and 1250 ° C. The sample A had a higher clearance, varying in color from pale cream to white at the higher temperatures. The linear shrinkage in this sample was higher than that obtained with sample B, however this sample B proved to possess a higher bending strength. Regarding to the color, sample B showed a gradual lightening tending to white, as well as the sample A. Therefore both kaolin samples can be applied to the formulations of white ceramics.
