Using the integral-balance method, the Stefan problem 
is solved for simply shaped crystals (a prism, a cylinder, and a sphere) 
grown in a supercooled melt. It is shown that the rate of crystal 
growth increases with the surface-to-volume ratio (in passage from 
a prism to a cylinder and a sphere). For all the three shapes of crystals 
studied the dependence of the speed of motion of the crystallization 
front on the supercooling is nonlinear and is characterized by a progressive 
increase.
