dc.descriptionWe report on the influence of temperature, mixing ratio and holding time of NaOH & KOH intercalations on the surface area, micropore volume and micropore width of pre-baked clay samples. Pore size & surface area analyzer was used to measure the surface area, micropore volume and average pore width using Dubinin-Radushkevich (DR) method. A meaning full effect was observed when the temperature was increased from ambient up to 150 degrees C in case of both intercalating agents. Increasing temperature beyond 150 degrees C caused a decline in surface area generation even up to 750 degrees C. The results also show that mixing ratio has a positive effect on the porosity and the micropore surface area increases as the mixing ratio increases in case of both intercalating agents. The influence of holding time shows two different trends. In case of NaOH, the porosity increases as the time increases while in case of KOH, the porosity decreases as the time increases. SEM, EDX and XRD studies were also performed. The results show effective insertion of the sodium and potassium into the clay matrix thereby causing generation of porosity.
