THERMAL EXPANSION OF LEAD
Dheer and Surange 1958, Ebert 1928, Nix and
MacNair 1942, Olsen and Rohrer 1957.
Dorsey 1908, Gruneisen 1910, Head and L que r
1952, Lindemann 1911, McLennan, Allen and
Wilhelm 1931.
Superconducting lead has a slightly greater
volume and a slightly smaller expansion coefficient
than normal lead according to data by
Olsen and Rohrer covering the region from lo
to the transititon temperature, 7.2OK. For
example, the difference in expansion coefficients
at 5OK is about 10%.
