Abstract
A stationary growth of the dendritic tip having the tip shape of an elliptical paraboloid in a binary liquid is considered. A method for constructing a selection criterion that allows one to obtain the growth rate and two radii of the dendritic tip as functions of undercooling is proposed. Selection constants are found theoretically for the n -fold crystalline symmetry. The theory is in good agreement with experimental data obtained on water and water solution previously described in literature.
