Problems arising in the process of growing advanced liquid crystals in zero gravity and ways to solve them
Abstract
This is explained by strong thermo gravitational, non-stationary convection, which leads to instability of crystal growth parameters.
The first results of growing crystals in microgravity showed the fundamental possibility of obtaining more perfect crystals due to the absence of gravitational convection.
However, under conditions of microgravity in crystalline solutions and melts, instead of terrestrial thermo gravitational, non-stationary convection, new possibilities appear for convective processes of a non-gravitational type - Marangoni convection, as well as (in the presence of residual gravity) small thermo gravitational processes that prevent the production of advanced homogeneous crystals.
Another problem is the absence, in contrast to terrestrial conditions, of the Archimedes force, which leads to the presence of gas inclusions in crystalline solutions and melts and, consequently, to the impossibility of obtaining advanced homogeneous crystals.
The article presents in detail the problems that arise when growing advanced mono crystals under microgravity conditions and ways to solve them.
