Smartphones. Smart Chemistry.
This article discusses how much of a scientific phenomenon smartphones are and how large of a part they play in our world today. They have evolved so much and at such a rapid pace and have changed technology forever. Chemistry is what allows your phone to function internally, as well as externally. Modern chemistry is to thank for this amazing gadget as it is the foundation of smartphones today.
Chemicals
Their importance and applications inside of smartphones.
Chemicals
Rare Earth Metals
Rare Earth Metals
Smartphones today contain up to 16 out of the 17 rare earth metals.
- Several of the colours you see on your screen come from these metals
- These metals are used in the circuitry of the phone
- Rare earth metals are also found in the speakers of smart phones
- The phone's ability to vibrate comes from the rare earth metals: neodymium and dysprosium

Main Chemical
Aluminosilicate - Al2SiO5
- Introduction to Gorilla Glass
- The process in which Aluminosilicate is used
Importance and Applications
Aluminosilicate is a very important chemical when it comes to the phone's screen.
- Aluminosilicate is the chemical that is used to make the glass
- It is a mixture of aluminum oxide and silicon dioxide
- silicon dioxide glass vs. aluminosilicate

High School Chemistry
Reactions Unit:
In grade 11 chemistry I learned about the different chemical reactions that can occur; combustion, decomposition etc.
The reaction that I learned about that applies to this article is single displacement reactions.
This helped me to understand how the Gorilla Glass reaction worked.
Chemical Reactivity
I selected a fairly unknown chemical, "aluminosilicate". It is a glass that is very uncommon and is only used for making cell phone screens. There are no other reactions that it takes part in.
Chemical Reactivity
Different forms of aluminosilicate glass:
- Calcium aluminosilicate - CaAl2Si2O8 *
- Sodium aluminosilicate - NaAlSi3O8 *
- Alkaline earth aluminosilicate glasses
- Alkali aluminosilicate glasses
Question For the Author
Have there been any alternatives to rare earth metals discovered that can be used in the technology industry?
Question For the Author
Why Everyone Should Read This Article
- cell phones are an enormous part of today's life
Why Everyone Should Read This Article
- Most people do not take chemistry's role in technology into account
- It dives into all of the aspects of your phone that involve chemistry. i.e. why your phone vibrates
- It explains the process in which the chemicals are used i.e. aluminosilicate in Gorilla Glass
- It goes on to explain the magic of touchscreens
