Zr 12x M x W 2 O 82y (M ΒΌ Sc, In and Y) solid solutions substituted up to x ΒΌ 0:04 for Zr(IV) sites by M(III) ions were synthesized by a solid-state reaction. X-ray diffraction experiments from 90 to 560 K revealed that all solid solutions had a cubic crystal structure and showed negative thermal ex
