This paper demonstrates the chemically assisted enhancement in porosity of l °Cal clay samples activated at a temperature of 150 ºC. Aluminosilicates enriched baked clay samples were used and hydro thermally treated with NaOH, KOH, Ba (OH)2 & ZrO. Pore size and surface area analyzer was used for the determination of surface area. Average pore width, pore volume and surface area were calculated. Treatment with NaOH and KOH has shown to be a very good activation pr °Cedure for high surface area development. Zirconium oxide has caused no pronounced effect on the development of surface area while barium hydroxide showed adverse effect and caused a decline in porosity
