Activated Bleaching Clay

Activated bleaching clay consists of SiO₂ 50–70%, Al₂O₃ 10–16%, Fe₂O₃ 2–4% and MgO 1–6%. It is an odourless, tasteless, non-toxic white to beige powder with a density of 0.6–0.8 g/cm³, insoluble in water, organic solvents, oils and fats.

Sodium-based bentonite is a type of bentonite primarily composed of montmorillonite, dominated by sodium ions between its layers. It has strong water absorption and swelling properties, good adhesiveness, and cation exchange capacity, making it a key material in industries such as casting, drilling mud, and iron ore pelletizing.
