Dry graphite
Lubricants used are oil, graphite, water and synthetic lubricants.
Olive oil is used and some times sunflower oil can also be used.

Graphite is the gain covalent structure often used in pencils and lubricants. It consists of layers of carbon atoms arranged in a hexagonal lattice that allows for smooth, low-friction movement between layers, making it ideal for use in lubricants.
Lauric acid is used to make lubricants
The term grease is used to describe semisolid lubricants. Although the word grease is also used to describe rendered fat of animals, in the context of lubricants, it typically applies to a material consisting of a soap emulsified with mineral or vegetable oil.
Clay
Lubricants.
Fatty acids are not commonly used as lubricants because they have poor stability and can oxidize easily, leading to degradation and potential damage to the machinery. Additionally, fatty acids tend to have a limited temperature range in which they can effectively lubricate, making them less versatile compared to other synthetic lubricants available in the market.
The radiation comes from the material used.
Silicon disulfide is a chemical compound composed of silicon and sulfur. It is a grey solid that is insoluble in water. Silicon disulfide is used in lubricants and as a semiconductor material.
Water-based lubricants are commonly used with nasal pharyngeal airways (NPAs) as they are safe and compatible with medical devices. Silicone-based lubricants should be avoided as they can degrade the material of the NPA. Always use a lubricant that is specifically recommended for medical devices.
