In a Bridgman-type apparatus for growing single crystals, a pair of different gradient sections is located around the respective liquid and solid phases of a sample undergoing solidification. Each gradient section is chosen with thermal characteristics matching the thermal properties of the sample and more particularly taking into consideration the difference in thermal conductivity between the liquid and solid phases. The result is a better match or control of the temperature profile between the furnace and the sample material undergoing solidification which results in improved interface shape control.
