摘要：

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 K.
