Measurements are reported of the thermal expansion, a, from 2 to 100 K and heat capacity from 1.5 to 20 K for a sample of Zerodur M and two samples of Zerodur for comparison. Zerodur M is a new glass-ceramic produced by Schott Glaswerke (Mainz), which has a near-zero thermal expansion coefficient at
The heat conductivity has been determined for lead, copper and tungsten. For lead an increase of the heat resistance is found at very low temperatures. This resistance is higher in the supraconductive state than in the state in which supraconductivity has been disturbed by means of a magnetic field.
