Powdered graphite is primarily known for its use as a lubricant. This is due to its unique physical properties, which allow it to reduce friction between surfaces. Graphite consists of layers of carbon atoms arranged in a hexagonal structure, which enables the layers to slide over one another easily. As a result, when applied as a lubricant, powdered graphite can effectively minimize wear and tear on mechanical components, making it ideal for use in situations where oil or liquid lubricants may not be suitable, such as in high-temperature environments or where a dry lubricant is preferable.

In addition, it is frequently used in locks, hinges, and other areas where lubrication is required without the mess of liquids. The ability of powdered graphite to withstand heat translates into its widespread application in various mechanical devices and systems. This characteristic plays a crucial role in industries that rely on machinery and equipment requiring smooth, friction-reduced operations.
