Akshoy Kumar Chakraborty is a retired research scientist with more than 40 years of experience in the clay/mullite research field of ceramics. He obtained his BTech in Chemical Engineering (1969), MTech in Glass and Ceramics (1970), and PhD (Sc; 1976) from Calcutta University, India. In collaboration with the National Physical Laboratory, New Delhi, India, he worked on the characterization of a certified silicon powder for X-ray diffraction and with Dr. K.J.D. Mackenzie (Gracefield Research Centre, New Zealand) on solid-state nuclear magnetic resonance studies on leached and heat-treated kaolinites. Dr. Chakraborty has received the International Plato Award for Educational Achievement by the International Biographic Centre, Cambridge, UK, and the Marquis Award. He has authored a book, Phase Transformation of Kaolinite Patents, and co-authored 45 articles and holds a few patents. He is a life member of the Indian Ceramic Society, the Indian Thermal Analysis Society, and the Indian Institute of Ceramics and a reviewer for the American Ceramic Society and Material Science.
