16/02/2022· Graphite is a greyish black compound and is completely opaque. Graphite is non inflammable in nature. The density of graphite is much lower than its polymorph, diamond. Graphite has a layered, planar structure and in each layer, constitute carbon atoms are connected to each other in a hexagonal lattice.

Minerals are naturally occurring material that has constant properties all the way through. In other words, if you have a mineral, all the different parts of it are the exact same material. Minerals have an internal structure, and there are hundreds of types. Rocks, on the other hand, have only three types: Igneous, Sedimentary, and Metamorphic.
13/01/2019· Diamonds and graphite are different forms of the same element, carbon, but their hardness varies because of their different internal structures. Diamonds are the hardest of all minerals. Each atom is strongly bonded to four others, forming a compact, rigid structure. In graphite, the atoms are arranged in layers that easily slip over each other.
Almost all minerals consist of a mixture of various chemicals, as, for example, all gems except for transparent diamonds. Diamonds are made of pure carbon, and the chemical composition doesnt differ from ordinary coal. The mineral bridgmanite is
Graphite, like diamond, is an allotrope of carbon. They are very similar to each other but the different structures of the molecule affect the chemical and physical properties. Graphite is made of layers of carbon atoms. These layers can slide over each other very easily. This means that it is very soft. It is a dull gray in appearance.
23/02/2018· Graphite, although a mineral, can behave like a metal and is capable of conducting electricity. That is why it is used in lithium ion batteries, acting as the graphite anode. Graphite has yet to take off as an industry in terms of the stock market, but given a little more time, this mineral might yet grow. Featured Image: depositphotos/ siimsepp
23/05/2018· Graphite. Graphite is a soft, black, metallic mineral composed of the element carbon . It is nontoxic and rubs off easily on rough surfaces, which is why graphite mixed with fine clay , rather than actual lead , is used to make pencil leads. The word graphite derives from the Greek gréphein, to write or draw.
