“…During the formation of an elementary crystal layer of thickness dδ per unit area, the amount of heat released is Lρ dδ (L denotes the latent heat of solidification and ρ the crystal density); the latter is being extracted through the cooler for a time interval dt. On this basis the following equation may be written (ČABRIĆ et al, 1990):…”

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.

“…Also, the development and improvement of the interior and exterior of air-cooled tube, (Fig. 1b) [a series of modular and movable pipes (bilateral thresholds) -see (6), slide bars -see (7), and modular plug heads -see (8)] enables regulation of the shape of the crystallization fronts and rates, down and up, i.e. on the surface and the bottom of the melt, in each crucible.…”

“…By the assumption that the liberated latent heat of solidification is equal to the heat removed by the airstream through the plug, the following expression for the crystallization rate R is derived [6]:…”

A modular air‐cooled tube, with a series of movable Tamman test tubes or plugs (modular unilateral and bilateral “crystallization comb”), installed in a laboratory tube furnace is presented. The setup allows easy regulation and simultaneous crystallization tests of a series of different crystallization parameters in crucible columns, enabling rapid acquisition of crystals. The relationship between the crystallization parameters has been given and numerically analyzed. This method can also be applied in crucible and chamber furnaces. (© 2011 WILEY‐VCH Verlag GmbH & Co.

“…positions of movable test sieve, simultaneously regulate different intervals of crystallization rates [3]. Crystallization rate intervals can also be regulated by the distance of the cooler from the furnace wall (b), thickness of the wall of the cooler and its heat conductivity, and lengths of the test tubes (see formula (1) of Ref.…”
