TLDR
In this paper, the coefficients of thermal expansion from 0 to 1800 K were investigated using accurate and precise experimental techniques and the results were used to establish analytical expressions for the coefficients for thermal expansion.Abstract:
Platinum has a face-centered cubic crystal structure and does not have any phase changes between absolute zero and its melting point at 2045 K High-purity platinum can be readily obtained in rod and sheet form and thus provides an excellent thermal expansion standard Five investigations that used accurate and precise experimental techniques were used to establish analytical expressions for the coefficients of thermal expansion from 0 to 1800 Kread more

High Temperature Structure and Thermal Expansion of Some Metals as Determined by X‐Ray Diffraction Data. I. Platinum, Tantalum, Niobium, and Molybdenum
TL;DR: The crystal structure and thermal expansion of platinum, tantalum, niobium, and molybdenum have been determined between 1100° and 2500°K as discussed by the authors, and the permanent elongation of tantalum wires, produced by annealing at temperatures between 2473° and 2773°K, appears to be caused by reorientation of crystal grains in the specimen and to preferred direction of crystal growth during annaling, rather than to a change in crystal structure.
