Abstract A method based on the Lyapunov stability theory has been developed for studying the stability of crystallization by capillary shaping techniques (including Czochralski, Stepanov, EFG, Verneuil and floating zone methods). The preliminary results of the analysis of stability shows that the crystallization by capillary shaping technique under microgravitation conditions is more stable in some cases than under the action of gravitation. To get deeper into details of the capillary shaping technique under microgravitation conditions, we have carried out model experiments using two immiscible liquids of equal density and crystallization of sapphire in terrestrial conditions with small Bond number. The experiments on the copper crystallization were realized in the high-altitude rockets. Our experiments on indium crystallization carried out in the orbital space probe “Salyut” yielded cylindrical specimens.
