Foseco Ferrous Foundryman's Handbook
The chilling effect of zircon sand can be used to produce favourable thermal
gradients that promote directional solidification giving sounder castings. The
thermal expansion coefficient of zircon is very low (Fig. 12.2) so that expansion
defects ...

Earth Processes: Reading the Isotopic Code
This is due to preferential exclusion of 230jh, relative to U, from the zircon
structure, the opposite of the effect documented in monazite. Preferential removal
of U relative to Pb seems unlikely since U is chemically bound in the zircon lattice
