A low-thermal-expansion ceramic with the composition Al0.8Mg0.6Ti1.6O5 that is isostructural to aluminium titanate Al2TiO5, was prepared by solid-state reaction of a mixture of α-Al2O3, MgO and TiO2-rutile. The synthesized material does not decompose after annealing for 250 h in the temperature range of 900–1175°C. The ceramic sintered at 1350°C has a 97% relative density, a grain size of ≈5 μm and an average thermal expansion coefficient between 80 and 1000°C of ≈2×10−6 K−1. Materials with the same composition, but obtained by reaction sintering, have a higher thermal expansion coefficient (4×10−6 K−1) and showed the presence of secondary phases.
