Critical temperature of copper
WebThe rate of cooling in this final firing must not exceed 100°/h until the temperature of the material is below 500 °C. This slow rate of cooling is an absolute necessity for producing superconductors with a critical temperature above the temperature of liquid nitrogen. http://hyperphysics.phy-astr.gsu.edu/hbase/Solids/coop.html
