GENERAL DESCRIPTION 
Hydrated alumina, also known as alumina trihydrate (ATH), or simply hydrate, is more accurately chemically designated as aluminum trihydroxide, Al(OH)3. It is a non-abrasive powder with a Mohs' hardness index of 2.5 - 3.5 and a specific gravity of 2.42. Alumina trihydrate is the largest volume flame retardant used in the world. On heating to 200°C, hydrated alumina decomposes into 66% alumina and 34% water. This irreversible process is, in part, what makes ATH an effective flame retardant.  Aluminium hydroxide is also used as an adsorbent, emulsifier, ion exchanger, mordant, antacid, and filtering medium. It is also used in the manufacture of paper, ceramics, printing inks, detergents, for waterproofing fabrics and in dentrifrices and antiperspirants
