Faculty of Applied Sciences submitted Q public paper Clay, XRF, elemental contents Clay has been considered as important material for man, either used as building materials, pottery or as components in material industry and technology. In the present study ten clay samples obtained from various locations in North-West Peninsular Malaysia were used. Majority of the clays were economically manufactured to be used as building materials or pottery. The objective of study was to determine the main elemental contents of the samples, and relate the results to the types of minerals, as well as to compare them with clays from other studies. In the study X-ray Fluorescence (XRF) coupled to samples dilution method and standard calibration samples was used. The elements detected in the study were Si, Al, Fe, Ti, K and Ca. Depending on locations, the percentage concentration ranged between 24.8 – 32.4 for Si, 10.8 – 19.0 for Al, 0.09 – 2.12 for Fe, 0.08 – 1.13 for Ti, 0.45 – 3.39 for K and trace amount of Ca and P. However, Mg that normally found in typical clay was not found in the studied samples. Comparing the oxide of the major elements with other studies, it was found that the clay samples contained mixtures of kaolinite (two-layered structure) and illite (three-layered structure) in which K is found in its interlayer space of the structure. 2008 submitted International Conference on X-ray in Research and Industry (ICXRI) 2008 Universiti Malaysia Sabah, Sabah, Malaysia 2 – 6 June 2008 conference FALSE Ahmad Saat & Zaini Hamzah, (2006) X-ray Diffraction Study of Clay from North-West Peninsular Malaysia, presented at the International Conference on X-ray Application in Research and Industries (ICXRI 2006), 6 – 8 August 2006, Putrajaya, Malaysia.
