    Abstract: In this research, soluble sodium silicate was extracted from rice husk ash. Rice husk in its as-received state was initially burnt in an open air to obtain the rice husk ash (RHA), which was later thermally treated inside the muffle furnace at 600°C for 5hrs to remove the carbonaceous matter and increase the silica (SiO2) content. The thermally tre... Show More
