Mined Earth Elements to Computers in Your Home and Busines

 

You call roofing companies CT to ensure that your house is protected from all foreign elements. This is true especially if you have your precious smart devices that make life easy and convenient. While the roofing part is secured, does it ever make you think about how your devices are manufactured or the materials used to make one?

In this article, we will try to cover the major hardware parts in your electronic devices and find out what materials are used to make them.

This is Where it All Starts

The most commonly used material in manufacturing electronics would be the silicon dioxide. This is mined as quartz or silica sand. It’s actually one of the most abundant elements on Earth and used in tons of different products.

Believe it or not, silicon dioxide is also among the vital ingredients in creating ferro-concrete which is used in most global construction projects, glassmaking, metal and chemical productions, coatings and paints, water production, solar panels and of course, for computer electronics.

From Sands to Chips

Silicon is basically derived from quartzite which is then mined from earth. Quartz will be melted and then after that, it’ll be crystalized by seed crystals and pulled out to long cylinder and cut using diamond saw. The end product will look like wafers which are then distributed to different factories to make various computer components like the ones in SSD memory.

The silicon’s high purity is bathed in sulphuric acid and hydrogen peroxide to be able to clean the wafers. After that, it’s bathed in sulphuric acid and deionized water in an effort to eliminate particulate matter present in the material. After its second bath, the oxide layer will be removed using hydrofluoric acid and deionized water. The final bath for the wafer is going to be in hydrochloric acid, deionized water and hydrogen peroxide.

Computer’s Performance

In order to boost the performance of CPU, Intel and IBM started using hafnium which is a rare metal that’s used as well for controlling rods of nuclear reactors. Regarding the technology behind how these companies do it though, it is a trade secret.
