Evaluation of Incorporation of Special Vitreous Residues in Mass for Porcelain Stoneware: Physical and Mechanical Properties
Abstract:
This study aimed to technological alternatives for reuse of vitreous residues from fluorescent lamps, which cause damage to the environment. It was prepared mass to white ceramic with and without lamps residues replacing partially feldspar in proportions of 5% and 10%. Samples were molded and fired at 1000 ° C, 1100 ° C, 1150 ° C, 1200 ° C and 1250 ° C. Physical and mechanical tests were: water absorption, linear shrinkage and rupture by flexural modulus. Samples with 10% of residues reached stability at temperature less than 1250 ° C in all determined properties, confirming the feasibility of these residues in ceramic masses. To optimize the study, it was prepared other samples in proportions of 15% and 20% of waste, at the same level of burning and testing. Results obtained ratified the possibility of using these residues as a flux in ceramic slurries.
