An exact calculation of crystal growth rates under conditions of constant cooling rate

The problem of crystal growth under conditions of constant cooling rate is solved. The solution is exact in the sense that the full Arrhenius form of the liquidus curve is used. Ths solution is compared to Minden's approximate treatment. The approximate result applies only for short values of the time or when the heat of solution is large with respect to the initial thermal energy. Experimental tests of the growth kinetics are emphasized. © 1973.
