WebCoefficient of Thermal Expansion of Platinum. Linear thermal expansion coefficient of Platinum is 8.8 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. WebThe results indicate that coefficient of the thermal expansion calculated from the EoS appeared to be high-precision because it is consistent with the data obtained at 1 atm. However, our results contradict α 0 value suggested by Rigby et al. (Brit Ceram Trans J 45:137-148, 1946) widely used in many physical and geological databases.
