Microstructural Analysis of Clay Ceramic Added with Argillite and Grog

Article Preview

Abstract:

The microstructure of a 1050oC fired clay ceramic added with both argillite and discarded ceramic waste, known as grog, was analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The objective was to evaluate not only the developed crystallographic phases but also the ceramic sintering conditions associated with the grog and argillite additions. The XRD results showed the presence of quartz and feldspar existing in the raw materials as well as hematite and mullite transformed at high temperature from the precursor clays. The SEM analysis revealed a consolidated ceramic structure in which the sintering process was effective in reducing the initial space between particles and thus improving the structural compactness.
