Activated Alumina Suppliers - China

Characteristic:

Activated alumina is manufactured from aluminum hydroxide by dehydroxylating it in a way that produces a highly porous material; this material can have a surface area significantly over 200 square metres/g.

The compound is used as a Activated Alumina desiccant (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 aluminum oxide (aluminium oxide, alumina; Al2O3), the same chemical substance as sapphire and rubies (but without the impurities that give those gems their color).

It has a very high surface-area-to-weight ratio.

That means it has a lot of very small pores, almost like tunnels, that run throughout it.

Application:

1 - Activated alumina ball is used for a wide range of adsorbent and catalyst applications including the adsorption of catalysts in polyethylene production, in hydrogen peroxide production, as a selective adsorbent for many chemicals including arsenic, fluoride, in sulfur removal from gas streams.

2 - Activated alumina is also used as a activated alumina desiccant, it works by a process called adsorption.

3 - Activated alumina is also widely used to remove fluoride from drinking water.

4 - Activated alumina filter, when used as a fluoride filter, can be regenerated by a solution of lye (sodium hydroxide; NaOH), sulfuric acid (H2SO4), or alum (KAl(SO4)2).

5 - In high vacuum applications, activated alumina powder is used as a charge material in foreline traps to prevent oil generated by rotary vane pumps from backstreaming into the system.

6 - Its mechanical properties and non-reactivity in the biological environment allow it to be a suitable material used to cover surfaces in friction in body protheses (e.g. hip or shoulder protheses).
