INFLUENCE OF SOME INTERCALATIONS ON ACTIVATION OF PRE-BAKED CLAY

We 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 aver...
