Influência da granulometria do vidro soda-cal de embalagem nas propriedades de sinterizados produzidos a partir de argila usada na indústria cerâmica do estado de Sergipe

Abstract

In the process of producing clay based sintered solid wastes such as packaging glass can be incorporated. In the literature there are several works in which glass is used as a raw material in the production of sintered clay, but there are few reports of the influence of its granulometry on sintering. The present work aimed to investigate the influence of the particle size of glass embedded in a clay that is used in the ceramic industry of Sergipe. The glass was incorporated into the clay at 0, 10, 20, 30 and 40% by weight, with two different mean glass particle diameters (450 and 37,5 μm). The formulations were characterized by dilatometry and were subsequently produced sintered with clay and glass formulas burned at three different temperatures (1050, 1100 and 1150 ° C), which were characterized by their visual appearance, shrinkage, loss of fire mass. , density evolution, water absorption, mechanical strength, fracture surface, and their properties were correlated with the microstructural evolution through the SEM technique. Particle size was a key parameter to ensure the efficiency of glass incorporation in clay.
