    Activated Alumina Ball (AAB106)

    Activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly

    porous material; this material can have a surface area significantly over 200 m²/g. The compound is used as adesiccant (to

    keep things dry by absorbing water from the air) and as a filter of fluoride,arsenic and selenium in drinking water.It is made

    of aluminium oxide (alumina; Al2O3), the same chemical substance as sapphire and ruby (but without the impurities that

    give those gems their color). It has a very high surface-area-to-weight ratio, due to the many "tunnel like" pores that it has
