Solving Problems Arising during the Monocrystals Growth in Microgravity Using Controlled Vibration
Abstract: Earlier studies of the vibration effect on a vessel with a fluid with gas bubbles dissolved in it permitted to establish the localization and stable position of the "swarm" of gas bubbles at a certain level of fluid in the vessel, corresponding to a certain frequency and vibration acceleration, as well as the volume of the "swarm" of gas bubbles. Controlling the "swarm" of gas bubbles in a fluid by …

Theoretical and Experimental Research of Phenomena Arising in a Vessel Containing the Bubbles Dissolved in the Fluid and the Air above Surface of Fluid under Impact of Vibration in the Acoustic Range both in the Terrestrial and Decreasing Acceleration of Gravity Conditions
Abstract: Under terrestrial conditions, gravitational forces prevent to obtain materials that are homogeneous in distribution components and phases. Strong thermo gravitational unsteady convection leads to instability of crystals growth parameters and limits the possibilities of obtaining the crystals with a high degree of homogeneity and perfect parity structures. The first results of crystals growth in microgravity showed the fundamental possibility of producing more advanced crystals due to the absence of gravitational …

Physical Features of Advanced Monocrystals Growth under Space Flight Conditions
Abstract: In terrestrial conditions, gravitational forces impede the production of materials with uniform distribution of components and phases. Strong thermo gravitational unsteady convection leads to instability of crystal growth parameters and limits the possibility of obtaining crystals with a high degree of homogeneity and structure with ideal parity. The first results of growing crystals under microgravity conditions showed the fundamental possibility of obtaining more perfect crystals due to the absence of …
