Deformação Piroplástica de Porcelanatos

Abstract

A deformação piroplástica pode ser definida como a deformação sofrida por uma peça cerâmica provocada por forças de gravidade e devido ao seu próprio peso durante o ciclo térmico perdendo assim o seu formato original. Esse tipo de deformação está relacionado com o excesso de fase líquida ou à baixa viscosidade da mesma no decorrer da queima e, por esse motivo, ocorre frequentemente em produtos de alta vitrificação como os porcelanatos. O desenvolvimento de novos produtos de grandes dimensões e espessuras cada vez menores tem agravado o aparecimento desse fenômeno. O objetivo do presente trabalho foi identificar as principais variáveis responsáveis pela deformação e sugerir alternativas para reduzi-la. No presente estudo foram caracterizadas seis composições típicas de porcelanatos e foi verificado que a substituição de algumas matérias-primas utilizadas na composição de massas de porcelanatos pode contribuir significativamente para reduzir a deformação piroplástica
