Abstract


Pakistan is a developing country which has huge deposits of kaolin (China clay) at Nagar Parker in Sindh province and in Khyber Pakhtunkhwa (KPK). The total reserves in Nagar Parker and KPK are estimated to be 4.33 and 2.81 million tons respectively. Nagar Parker kaolin was used as an indigenous source to covert kaolin in to a value added product as zeolite Y with Si/Al ratio 3.57. The kaolin was believed an inactive phase and possess inert Si-O and Al-O structure which was transformed to active phase through fusion at elevated temperature (850oC) and autogeneous pressure in the presence of alkali hydroxide(NaOH).The raw kaolin and final product was characterized by X-ray Diffractometer (XRD), Scanning Electron Microscope (SEM), X-ray Florescence Spectrometer (XRF) and Particle size analyzer.
