Silica Gel Uses on Our Life

Silica Gel Uses on Our Life

We all are familiar with silica gel. We can see the small packets inside some medicine bottles, inside our laptop bags or inside our shoeboxes. That means in our daily life silica gel is having a major role. Day by day the application area of silica gel is increasing. We can see two good examples of this.

Prevent your car windshield from moisture jam

A common issue during rainy and winter season, fog on car windshield is only because of the moisture present inside the car. Get rid of this issue by placing a couple of silica gel packs on the dashboard closer to the windshield and witness the magic. These tiny packets of silica gel can absorb moisture, therefore it will help to avoid this issue.

Important for your gym bag

Gym bag stores your sweaty towels, shoes, and socks and the smell seeps in the bag for long. Manage this problem by placing a couple of silica gel packets inside the bag which will suck all the moisture created by sweat and the smell too.

PRODUCTION OF ACTIVATED ALUMINA

In most cases, activated alumina starts out as aluminum hydroxide (gibbsite, boehmite, etc.) – a material obtained through a series of chemical reactions in the Bayer process used to transform bauxite ore into alumina.

ACTIVATED ALUMINA CALCINATION

Once the aluminum hydroxide has been produced, it is thermally treated via calcination in a rotary kiln. This calcination step serves to dehydrate or remove bound moisture from the aluminum hydroxide in order to produce activated alumina, or aluminum oxide (Al2O3).

Activation, a phase in which the activated alumina structure becomes highly porous, occurs within a specific temperature range, with process parameters such as residence time and temperature profile used to control the properties of the end product. The makeup of the original bauxite source can also influence the characteristics of the end product.
