New Class of Apparatus for Crystal Growth from Melt

Design and Calculation for Test Tube with the Aim of Regulation Simultaneous Crystallization Tests

“…By varying the internal and external shapes and dimensions of the cooler, a set of "crystallization combs/keys" can be modeled for tests over a different range of crystallization fronts and rate intervals. The air cooled test tube can be installed into a tube furnace in a horizontal position ("crystallization shelf"-Figures 16 and 17 in [6]) or vertical position ("crystallization corncob"- Figure 13 in [6]). Several different air-cooled test tubes (a family group of "crystallization keys/combs") can be installed in the chamber furnace ( Figure 11 in [6].…”

This increases the number of simultaneous crystallization tests (comb) of different crystallization parameters, using a low-budget, modular, easy to install and remove, portable ("pocket") device, i.e.…”
