In chemistry, graphite is a form of carbon in which the link between carbon atoms are strong to form a layer, but the link between the layers are weak. Its molecular weight = 12.01 gm. In layman’s term, graphite is a very soft, shiny, and greasy mineral dark and grey in colour and also known as the world’s softest mineral. Due to graphite’s greasy nature, it can leave a mark on anything; that is why it is used most of the time in pencils for writing on papers and drawing. Extensive years of research have shown that graphite is an impressive mineral because it has numerous outstanding properties, and one of them is to conduct electricity and heat very well. There are many uses of graphite; some of the important ones are as follows.
1. Writing Materials
The most common and day to day use of graphite is making lead pencils, and the lead is basically a mixture of clay and graphite. The word graphite is a Greek letter word, which means ‘to write.’
2. Lubricants / Repellents
Graphite is used in lubricants like grease and other similar types of lubricants to reduce friction and it is also used in car breaks, clutches, and so on.
3. Graphite Mold
Graphite is also used in mold making for casting purposes, and the majority of the graphite mold makers provide graphite molds, which are usually used for casting zinc-aluminum alloy parts.
4. Nuclear Reactors
Graphite is used in nuclear reactors because it absorbs fast-moving neutrons; as a result, it stabilizes the nuclear reaction.
