It is process of deposition that transforms the gas into solid. The deposition considered to be a thermodynamic procedure and occurs when certain characteristics (such as pressure and temperature) change as the system moves from its initial equilibrium state to a final state. For instance: anti-reflective, solar cells, snow.
In method that reverses the method that deposition undergoes sublimation which is the change directly between the liquid and gaseous one without passing across the state of liquid. Deposition is sometimes referred to as reverse sublimation.
There different deposition methods including some that are natural (manifested naturally by nature) and others implemented through technological processes that enable the creation of objects made of pure substances or by using a solid material to cover different objects.
Example Of Deposition
- The electrical conductivity. Metallic films as well as transparent conductive oxides superconducting coatings, and superconducting films are produced by chemical deposition.
- Anti-reflective. Magnesium fluoride is employed on optical lenses to create anti-reflective effects.
- Solar cells. The process of deposition of a film is achieved via chemical deposition.
- Electrical connections. Deposition of metal is used to cover electrical connections within integrated circuits.
- Artificial diamonds. They are made by gaseous carbon atoms by chemical deposition.
- Silicon dioxide. Silane is formed by oxygen, dichlorosilane and the nitrous oxide, silane vapours can be made by chemical deposition.
- Semiconductor devices. Semiconductor films, electrically insulating film are applied by chemical deposition.
- Frost. In frozen air water vapor is transformed directly into icewithout the need to change into a liquid.
- Tools. Deposition of titanium nitride can be utilized to reduce wear of tools.
- Generation and energy conservation. Low-emissivity coatings solar absorption coatings mirrors and glass, thin film photovoltaic solar cells, and smart films are applied using chemical deposition.
- Acid rain. The sulfur oxide and nitrogen residues release into the air through various industries, and they are transformed to sulfuric acid and nitric. They fall in solid form to the earth (dry deposition) or are mixed with snow or rain. Acid rain can have devastating effects on various ecosystems including terrestrial and aquatic and can also increase the deterioration of buildings.
- Snow. In the frozen air, water vapor transforms directly into the form of ice, and does not change into liquid.
- Silicon nitride. It is formed into a solid by the reaction of ammonia and silicon, by chemical deposition.
- Magnet films. They are applied by chemical deposition.
- Films with optical properties. Filters with anti-reflectivity, also known as optical coatings may be applied to a variety of optical products (photography filming, vision) by chemical deposition.
- Tribological layer. Coatings that are hard, durable coatings, and lubricating films are formed by chemical deposition.
- Coatings with reflective properties. Mirrors and hot mirrors may be produced through chemical deposition.
