Abstract
The products of refractory materials are used for lining furnace, incinerators and kilns among other uses and they have the potential of withstanding high temperature without deformation. The objective of the research was to charac-terize the clay soil sample collected from Tshwane University of Technology in Pretoria. The sample, collected from a location Latitude 25.0969°S and Longi-tude 28.1624°E, was oven-dried, pulverized and sieved in the laboratory. Min-eralogical and elemental compositions of the sample were determined by using X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF) and Scanning Electron Microscopy (SEM) analytical methods. The XRF analysis revealed Fe2O3, Al2O3 and SiO2 as the major constituents, while the other elements occur in minor quantities. Mineralogically, the three samples contain Montmorillonite, Kaolinite and Bentonite, while Samples A contained Quartz in addition to ear-lier mentioned minerals, samples B and C contained Albite.

Summary
Refractory material has the potential of withholding high temperature without deformation or breaking. The products of such materials are used for linings kilns, incinerators and furnace among others. They depend on their chemical nature which is neutral [1] [2]. Properties of refractory materials include: increase in melting points associated with their stability and high resistance to corrosion by slags. Research works have been carried out on the development of good refractory materials mostly in western countries [3] [4] [5] [6].
