Bulk thermal expansion properties of 19 members of the A(2)M(3)O(12) family
of tungstates and molybdates were determined from room temperature to 800
degrees C. The observed behavior ranges from strong negative thermal expans
ion (alpha = -11 x 10(-6) K-1) in Sc2W3O12 to near zero thermal expansion i
n Al1.68SC0.02In0.30W3O12.
