Question

7. (a) What is graphite?​

Answer 1

Graphite archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure. It occurs naturally in this form and is the most stable form of carbon under standard conditions. Under high pressures and temperatures it converts to diamond.

Answer 2

Graphite is a mineral composed exclusively of the element carbon.

Graphite has the same chemical composition as Diamond, which is also pure carbon, but the molecular structure of Graphite and Diamond is entirely different. This causes almost opposite characteristics in their physical properties.

Explanation:

Graphite is rather common mineral, but fine crystals are rare. Most Graphite mining areas produce enormous quantities from a single or several large Graphite veins, but collector specimens in good crystals are not commonly encountered.

uses

Graphite is mostly used for refractory, battery, steel, expanded graphite, brake linings, foundry facings, and lubricants. ...

Graphite blocks are used in blast furnace linings where the graphite's high thermal conductivity is very critical.
