	~~===Liquid~~ Lubricants~~===~~		Lubricants can be classified into several types based on their physical state and application:

	~~===Semi-Solid Lubricants===~~		Liquid lubricants, such as [[motor oil]], are the most common type. They are used in a wide range of applications, from automotive engines to industrial machinery. Liquid lubricants can be further divided into:

	~~Semi-solid lubricants, or~~ [[~~grease~~]]~~, are used where a liquid lubricant would not stay in place~~. ~~They are often used in applications such as bearings, where they~~ provide ~~a constant layer of lubrication~~.		* '''Mineral Oils''': Derived from refining [[crude oil]].
			* '''Synthetic Oils''': Chemically engineered to provide superior performance.
			* '''Biodegradable Oils''': Made from renewable resources and designed to be environmentally friendly.

	===Solid Lubricants===		=== Solid Lubricants ===

	Solid lubricants, such as [[graphite]] and [[molybdenum disulfide]], are used in ~~extreme conditions~~, such as high ~~temperatures~~ or ~~pressures. They are often used~~ in ~~applications where other types of lubricants would fail~~.		Solid lubricants, such as [[graphite]] and [[molybdenum disulfide]], are used in applications where liquid lubricants are not suitable, such as in high-temperature environments or in vacuum conditions.

	==~~Applications of Lubricants~~==		=== Greases ===

	~~Lubricants~~ are used in a ~~wide variety~~ of ~~applications~~, ~~including~~:		Greases are semi-solid lubricants that consist of a liquid lubricant mixed with a thickening agent. They are used in applications where a liquid lubricant would not stay in place, such as in [[bearings]] and [[gears]].

			== Functions of Lubricants ==

			Lubricants serve several important functions in mechanical systems:

			* '''Reducing Friction''': By creating a film between moving surfaces, lubricants reduce the direct contact and thus the friction between them.
			* '''Cooling''': Lubricants can carry away heat generated by friction, helping to prevent overheating.
			* '''Cleaning''': They can help remove debris and contaminants from surfaces.
			* '''Protection''': Lubricants can protect surfaces from corrosion and wear.

'''Lubricant'''

A '''[[Lubricant]]''' is a substance, often a liquid, introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces. The property of reducing friction is known as lubricity.

==Types of Lubricants==

Lubricants are typically used to separate moving parts in a system. They can be classified into three main categories: liquid, semi-solid, and solid.

===Liquid Lubricants===

Liquid lubricants, commonly known as [[oil]], are used in various applications, from automotive engines to industrial machinery. They are typically composed of a base oil and various additives to enhance their performance characteristics.

===Semi-Solid Lubricants===

Semi-solid lubricants, or [[grease]], are used where a liquid lubricant would not stay in place. They are often used in applications such as bearings, where they provide a constant layer of lubrication.

===Solid Lubricants===

Solid lubricants, such as [[graphite]] and [[molybdenum disulfide]], are used in extreme conditions, such as high temperatures or pressures. They are often used in applications where other types of lubricants would fail.

==Applications of Lubricants==

Lubricants are used in a wide variety of applications, including:

* [[Automotive industry|Automotive]]: Lubricants are used in engines, transmissions, and other components to reduce friction and wear.
* [[Industrial machinery|Industrial]]: Lubricants are used in machinery to reduce friction, prevent wear, and prolong the life of the equipment.
* [[Medical industry|Medical]]: Lubricants are used in a variety of medical applications, from surgical instruments to personal lubricants.

==Environmental Impact==

The environmental impact of lubricants is significant. Many lubricants are not biodegradable, and their use can result in pollution of water and soil. Efforts are being made to develop [[biodegradable lubricants]] to reduce this impact.
