Natural graphite is used in lubricants because:

1. Great Lubrication: Its layers slide easily, reducing friction between parts.

2. High Temperature Resistance: It works well even at high temperatures.

3. Chemical Stability: It doesn’t react with many chemicals, so it stays effective.

4. Reduces Friction: Helps parts move smoothly and efficiently.

5. Flexible Use: Can be used in powders, pastes, or mixed with oils for different needs.
