Crystallization support tube in a laboratory furnace

Abstract

Design of modular, simple to build and handle air cooler ('crystallization support tube') installed in a laboratory tube furnace is presented. The setup allows easy regulation and simultaneous crystallization tests of different temperature gradients, shapes of crystallization fronts and rate intervals in crucibles and Tamman test tubes, enabling fast studies of obtaining crystals. The relationship between the crystallization parameters has been derived and numerically analyzed. This method can also be applied in crucible or tube furnaces.
