The Chemistry of iphones

Introduction:

I love my iPhone. It goes with me everywhere, and you will be hard pressed to find a time where it is not in my hand. I know that iPhones are popular with many other people, so researching the chemistry and composition of iPhones is something that I can most definitely do and love. I’ve never thought about chemistry and iPhones combined into one idea, so this project was fun as well as interesting.

Oxygen

Potassium (screen is dipped in potassium ions to make it stronger)

Alumina (Al2O3)

Silica (SiO2)

Aluminosilicate (Al2SiO5)

Sodium

Touch screen:

Indium

Oxygen

Tin

Wiring:

Copper

Silver

Gold

Tantalum

Speaker / microphone:

Nickel

Antimony

Arsenic

Phosphorus

Gallium

Solders:

Tin

Lead

Casing:

Carbon

Magnesium

Bromine

Nickel


Main chemicals, components, and compounds:


Potassium is an element that is only found in nature within compounds due to its extreme reactive tendencies. This element is, however, used in our iPhone screens. The glass of an iPhone contains sodium, another element. Potassium and sodium are often partners in crime, and instances in iPhone screens are no exception. Glass screens are used on an iPhone and they are full of sodium ions. Hot, liquid potassium salts are utilized to strengthen the notorious iPhone glass. The sodium ion-filled glass will be dipped in this hot potassium salt bath and the sodium ions will be replaced with the larger potassium ions. The potassium ions are squeezed into the holes left by the sodium ions. This will compress the glass, therefore making it stronger.


Rare earth metals are utilized in the iPhone screen as well as potassium and sodium. These earth metals are used to create the bright colors we all see in our little handheld devices. Many of these elements have very few stable isotopes, but the elements can also be synthesized.


Chemistry’s Role

iPhones have an abundance of different elements and compounds that are used for a multitude of different jobs. Different utilizations of the elements and compounds means a completely different job in each of its different locations. The ion exchanges that occur in the screen are based in studies of the ions and different parts of chemistry that can apply to ions and their exchanges, for example. Chemistry is all over an iPhone, you just have to look for it.
