Scientific fundamentals: Graphite Usage As A Lubricant
Gain knowledge about the use of graphite by top graphite mining survey companies in India. Here is what you should know about graphite usage in lubrication in brief.
The lattice structure of graphite gives way to its unique properties. The reason why graphite gets preference over others is because of its high conductivity. The structure of graphite is such that the arrangement of carbon atoms comes in layers through covalent bonds.
Classification Of Graphite-
There are two main classifications of graphite: natural and synthetic.
Natural Graphite-
Natural graphite is usually found in association with feldspars, mica, quartz, pyroxene, rutile, pyrites, and apatite which You can easily divide it into three types: flake graphite, crystalline graphite, and cryptocrystalline graphite.
Synthetic graphite-
Synthetic graphite is a material consisting of graphitic carbon obtained by graphitizing non-graphitic carbon. This happens by CVD from hydrocarbons at temperatures above 2500 K, by decomposition of thermally unstable carbides. Or another process is by crystallizing from metal melts supersaturated with carbon.
Use Of Graphite In Electro-Metallurgy:
Graphite, in powder metallurgy, which acts as an alloying element to increase the strength of sintered parts. Graphite with different grain sizes finds application in metal graphite alloys, depending on the sintering process. The particle size of graphite needs to have an optimal relation to the metallic particle size. High purity and fast reactivity of the used graphite source is necessary for the following reasons:
- To get a short production time
- A density as high as possible
- A high tensile strength
The quality of graphite should be consistent to secure complete process stability for the producers engaged in the sector of powder metallurgy. The various applications belonging to powder metallurgy parameters of graphite include particle size, purity, particle shape, and surface. These attributes ensure that the tailor-made graphite grades and also, specific characteristics are an integral part of the entire process.
Graphite Usage In Lubrication:
One of the main ingredients for lubricants like grease is graphite. The lubricating mechanism of graphite is mechanical in nature and results from the sliding of one graphite particle over another graphite particle. This mineral reacts with atmospheric water vapor and also, creates a thin film or layer over the surface to reduce friction. More importantly, you will find graphite used in car brakes and also, clutches.
