Graphite is a non metallic conductor of electricity so is cheap,insoluble in water,acids and bases, and is non corrosive material.
It is not always used for this purpose. However in the case of motor brushes, it is used because it is a conductor of electricity and is soft and self lubricating.
The structure of graphite accounts for the design of graphite electrodes in the sense that the tight structural composition of graphite makes it easy for them to be arranged in electrodes.
electrodes are used in all types of electric furnaces.
Dry cell graphite electrode when treated with permanganate can be used as a hydrogen ion sensor. where activated dry cell graphite electrode seem to be suitable as potentiometric indicator electrodes. :)
The electrical conductivity
Tt depends on the metal which is the cathode and which is the anode. However, in most cases, graphite is the cathode and the metal is the anode. the strictly correct answer is that BOTH the metal and the graphite rod are electrodes. You must have two electrodes minimum to create a cell.
graphite is used as lubricant in machinery.also it is used in making leads of pencils.hence graphite is useful.
1) Graphite is used for making the cores of our pencils called pencil leads. 2) It is used for making carbon electrodes. 3) Powdered graphite is used as lubricant.

Dry graphite
Various elements are used for making electrodes like copper, zinc, aluminium, chlorine, mercury, platinum etc. Elements for making electrodes are selected on the basis on their relative tendencies to gain and loose electrons.
Carbon applications:- as diamond to cut glass and for polishing- as graphite for electrodes, crucibles, etc.- as pencil mine- as carbon black
The main use is making the "lead" or graphite in pencils. The lead in pencils is actually graphite. If it was real lead it would be very dangerous.
