Thermodynamic properties

melting_point(atomicnumber::Int)
melting_point(element::String)

Melting point of a given element at standard pressure (1 atm).

Example:

julia> melting_point("Li")
453.65

svp(atomicnumber::Int, temp::Real)
svp(element::String, temp::Real)

Saturated vapor pressure, p (in Pa), of a given element for a given temperature T (in K),

\[\mathrm{log_{e}}p=A+B/T+C\mathrm{log_{10}}T+D\cdot T/1000,\]

where A,B,C,D, are the Antoine coefficients collected in CamiXon.dictAntoineCoefficient.

Examples:

julia> svp("Li", 623.0)
0.0015230367024569058

latent_heat_vaporization(atomicnumber::Int, temp::Real)
latent_heat_vaporization(element::String, temp:Real)

Latent heat of vaporization, L(T) (in Joule/K), of a given element for temperature T (in K),

\[L(T) = -(B +C\cdot T \mathrm{log_{10}}T+D\cdot T^2/1000),\]

where A,B,C,D, are the Antoine coefficients collected in CamiXon.dictAntoineCoefficient.

Example:

julia> latent_heat_vaporization("Li", 623.0)
-18473.64020109123

dictAntoineCoefficient

Antoine coefficients [A,B,C,D] for temperature ranges below and above the melting points from dictMeltingPoint. These coefficients are used in the Antoine equation to calculate the saturated vapor pressure p (in Pa) at temperature `T (in K),

\[\mathrm{log_{e}}p=A+B/T+C\mathrm{log_{10}}T+D\cdot T/1000.\]

Currently, only the coefficients for the metalic elements are implemented - see C. B. Alcock, V. P. Itkin and M. K. Horrigan, Canadian Metallurgical Quarterly, 23, 309 (1984).

Note that the melting point is taken to be pressure independent.

Examples:

To calculate the saturated vapor pressure of Li (in Pa) at T=623 K we use the Antoine equation implemented in thefunction svp.

julia> svp(55, 400)
