Abstract

In this paper it is shown in which kind a stable and convex static meniscus, appropriate for the growth of a single crystal ribbon with specified half thickness, can be created in strictly zero gravity by choosing the pressure of the gas flow introduced into the furnace (for release the heat). The method is based on explicit formulas established for materials for which the contact angle αc and growth angle αg satisfy: 0<αc<π/2; 0<αg<π/2; αc<π/2-αg . The dependence of the obtained static meniscus shape and size on the shaper half thickness is also discussed. The procedure is numerically illustrated and the results are compared with those obtained on the ground..
