Abstract
SUMMARY: The mineralogy and chemistry of three clay raw materials and three types of brick product have been examined by transmitted light and scanning electron microscopy, X-ray diffraction and X-ray fluorescence analysis. The clays contain varying proportions of illite, kaolinite, vermiculite, quartz, calcite, rutile and hematite. The bricks consists of mullite, cristobalite, quartz, feldspars, spinel, rutile, illite and glass. The calcium-rich brick also contains wollastonite and gehlenite. Electron microprobe analyses of relict feldspars, new pyroxenes and matrix have been made, leading to an estimation of the glass composition. Examination of heated test pieces of each clay has shown the sequences of mineralogical change. This preliminary appraisal provides a basis for further work to elucidate the mineralogical reactions taking place in brickmaking.This publication has 2 references indexed in Scilit:
