Maximum Pull Rate for Czochralski Crystal
Hint: drag mouse to change diameter.
Constants used to calculate the maximum pull rate for CZ crystal  
symbol  Value 
L  430 cal/g 
N  2.33 g/cm^{3} 
s  5.67´10^{5} erg/cm^{2}·sec·K^{4} 
e  0.55 
k_{M}  0.048 cal/sec·cm·K 
T_{M}  1690 K 



We can see that the maximum pull rate is inversely proportional to the square root of the crystal radius (diameter). Actual pull crystal pull rates are less than those calculated by the formula above.
