Applications of Neon

Neon is often used in signs and produces an unmistakable bright reddish-orange light. Although tube lights with other colors are often called “neon”, they use different noble gases or varied colors of fluorescent lighting. Neon is also used to make high-voltage indicators and switching gear, lightning arresters, diving equipment and lasers. Liquid neon is an important cryogenic refrigerant. It has over 40 times more refrigerating capacity per unit volume than liquid helium, and more than 3 times that of liquid hydrogen.

Production and Price of Neon

Raw materials prices change daily. They are primarily driven by supply, demand and energy prices. In 2019, prices of pure Neon were at around 330 $/kg.

It is commercially extracted by the fractional distillation of liquid air. Since air is the only source, it is considerably more expensive than helium. Neon, as liquid or gas, is relatively expensive – for small quantities, the price of liquid neon can be more than 55 times that of liquid helium. Driving neon’s expense is the rarity of neon, which, unlike helium, can only be obtained from air.

Mechanical Properties of Neon

Strength of Neon

In mechanics of materials, the strength of a material is its ability to withstand an applied load without failure or plastic deformation. Strength of materials basically considers the relationship between the external loads applied to a material and the resulting deformation or change in material dimensions. In designing structures and machines, it is important to consider these factors, in order that the material selected will have adequate strength to resist applied loads or forces and retain its original shape. Strength of a material is its ability to withstand this applied load without failure or plastic deformation.

For tensile stress, the capacity of a material or structure to withstand loads tending to elongate is known as ultimate tensile strength (UTS). Yield strength or yield stress is the material property defined as the stress at which a material begins to deform plastically whereas yield point is the point where nonlinear (elastic + plastic) deformation begins.

Ultimate Tensile Strength of Neon

Ultimate tensile strength of Neon is N/A.

Yield Strength of Neon

Yield strength of Neon is N/A.

Modulus of Elasticity of Neon

The Young’s modulus of elasticity of Neon is N/A.

Hardness of Neon

In materials science, hardness is the ability to withstand surface indentation (localized plastic deformation) and scratching. Brinell hardness test is one of indentation hardness tests, that has been developed for hardness testing. In Brinell tests, a hard, spherical indenter is forced under a specific load into the surface of the metal to be tested.

Brinell hardness of Neon is approximately N/A.

The Vickers hardness test method was developed by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. The Vickers hardness test method can be also used as a microhardness test method, which is mostly used for small parts, thin sections, or case depth work.

Vickers hardness of Neon is approximately N/A.

Scratch hardness is the measure of how resistant a sample is to permanent plastic deformation due to friction from a sharp object. The most common scale for this qualitative test is Mohs scale, which is used in mineralogy. The Mohs scale of mineral hardness is based on the ability of one natural sample of mineral to scratch another mineral visibly.

Neon is has a hardness of approximately N/A.

Neon – Crystal Structure

A possible crystal structure of Neon is face-centered cubic structure.

In metals, and in many other solids, the atoms are arranged in regular arrays called crystals. A crystal lattice is a repeating pattern of mathematical points that extends throughout space. The forces of chemical bonding causes this repetition. It is this repeated pattern which control properties like strength, ductility, density, conductivity (property of conducting or transmitting heat, electricity, etc.), and shape. There are 14 general types of such patterns known as Bravais lattices.

Thermal Properties of Neon

Neon – Melting Point and Boiling Point

Melting point of Neon is -248°C.

Boiling point of Neon is -248.7°C.

Note that, these points are associated with the standard atmospheric pressure.

Neon – Thermal Conductivity

Thermal conductivity of Neon is 0.0493 W/(m·K).

The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance’s ability to transfer heat through a material by conduction. Note that Fourier’s law applies for all matter, regardless of its state (solid, liquid, or gas), therefore, it is also defined for liquids and gases.

Coefficient of Thermal Expansion of Neon

Linear thermal expansion coefficient of Neon is — µm/(m·K)

Thermal expansion is generally the tendency of matter to change its dimensions in response to a change in temperature. It is usually expressed as a fractional change in length or volume per unit temperature change.

Neon – Specific Heat, Latent Heat of Fusion, Latent Heat of Vaporization

Specific heat of Neon is 0.904 J/g K.

Heat capacity is an extensive property of matter, meaning it is proportional to the size of the system. Heat capacity C has the unit of energy per degree or energy per kelvin. When expressing the same phenomenon as an intensive property, the heat capacity is divided by the amount of substance, mass, or volume, thus the quantity is independent of the size or extent of the sample.

Latent Heat of Fusion of Neon is 0.3317 kJ/mol.

Latent Heat of Vaporization of Neon is 1.7326 kJ/mol.

Latent heat is the amount of heat added to or removed from a substance to produce a change in phase. This energy breaks down the intermolecular attractive forces, and also must provide the energy necessary to expand the gas (the pΔV work). When latent heat is added, no temperature change occurs. The enthalpy of vaporization is a function of the pressure at which that transformation takes place.

Neon – Electrical Resistivity – Magnetic Susceptibility

Electrical property refers to the response of a material to an applied electric field. One of the principal characteristics of materials is their ability (or lack of ability) to conduct electrical current. Indeed, materials are classified by this property, that is, they are divided into conductors, semiconductors, and nonconductors.

Electrical Resistivity of Neon

Electrical resistivity of Neon is — nΩ⋅m.

Electrical conductivity and its converse, electrical resistivity, is a fundamental property of a material that quantifies how Neon conducts the flow of electric current. Electrical conductivity or specific conductance is the reciprocal of electrical resistivity.

Magnetic Susceptibility of Neon

Magnetic susceptibility of Neon is N/A.

In electromagnetism, magnetic susceptibility is the measure of the magnetization of a substance. Magnetic susceptibility is a dimensionless proportionality factor that indicates the degree of magnetization of Neon in response to an applied magnetic field.
