The Influence of Sintering Temperature on Ceramic Material with Addition of Mill Scale

Abstract

This work aims to evaluate the influence of temperature sintering of a ceramic mass to characterize the properties of a ceramic mass obtained with the addition of mill scale. This residue is consisting of iron oxides and can be used in replacing pigments used in ceramic materials. The constitution of mixture was performed after chemical characterization of the ceramic samples, with addition of 5% in weight of mill scale. Test specimens were sintered at temperatures of 900oC, 950oC and 1000oC. The samples were characterized by loss on ignition, linear shrinkage, water absorption, flexural strength by 3 points and colorimetric test. The results indicate that different firing temperatures influenced the strength and tone of the specimens tested and, allowing the application these materials as structural ceramic.
