“…Another possible way is to use ground clay minerals obtained by high-energy ball milling (Tao et al, 2014). On the other hand, a stable hydrated kaolinite pre-cursor with d 001 = 0.84 nm was prepared successfully by heating the as-prepared kaolinite-hydrazine intercalate, at temperatures between 40 and 70°C (Kaden et al, 2014).…”
