ABSTRACT



A study of the mineralogical composition of Iloilo Ball Clay was conducted. Various methods for mineral analysis were applied namely X-ray Diffraction Analysis, Thermo-Gravimetric Differential Thermal Analysis, Infrared Analysis, Scanning Electron Microscopy, Optical Microscopy and Chemical Analysis. The raw sample is composed of the minerals-quartz, disordered kaolinite, rnagnetite and montmorillonite. Organic matter and volcanic glass were also detected.

Fractions of 2> , 2-5 , 5-8 , 8-20 and residual portion were obtained. By X-ray Diffraction Analysis, the 2 > specimen is mainly disordered kaolinite. Scanning Electron Micrographs showed platy, hexagonal crystals. Heat treatment at various temperatures of this specimen
showed the subsequent thermal transformation of a typical kaolin. The remaining fractionated portions showed the dominance of ∞-quartz.
