Types of Solid Lubricants

• Graphite: This is a commonly used solid lubricant due to its low friction properties and ability to withstand high temperatures.
• Molybdenum Disulfide (MoS₂): MoS₂ is another popular solid lubricant with excellent lubricating properties, especially in high-pressure and extreme temperature environments.
• PTFE (Polytetrafluoroethylene): Commonly known as Teflon, PTFE is a synthetic solid lubricant known for its low friction and non-stick properties.
• Graphene: This relatively newer material shows promise as a solid lubricant due to its exceptional strength and lubricating capabilities at the nanoscale.
• Other Materials: Solid lubricants can also be made from materials such as boron nitride, diamond-like carbon (DLC), and various metal oxides.
