name = 'ThO2'

String identifying the material

propertyValidTemperature = {'linear expansion': ((298, 1223), 'K')}

Dictionary of valid temperatures over which the property models are valid in the format ‘Property Name’: ((Temperature_Lower_Limit, Temperature_Upper_Limit), Temperature_Units)

setDefaultMassFracs()

ThO2 mass fractions. Using Pure Th-232. 100% 232 Thorium: 232.030806 g/mol Oxygen: 15.9994 g/mol

2 moles of oxygen/1 mole of Thorium

grams of Th-232 = 232.030806 g/mol* 1 mol = 232.030806 g grams of Oxygen = 15.9994 g/mol* 2 mol = 31.9988 g total=264.029606 g. Mass fractions are computed from this.

linearExpansion(Tk=None, Tc=None)

m/m/K from IAEA TE 1450

linearExpansionPercent(Tk=None, Tc=None)

Approximate the linear thermal expansion percent from the linear expansion coefficient, taking 298K as the reference temperature.

thermalConductivity(Tk=None, Tc=None)

W/m-K from IAEA TE 1450

meltingPoint()

melting point in K from IAEA TE 1450
