The development of science and technology in certain cases requires the use of materials with low coefficients of thermal linear expansion. At present, fused quartz, spodumene, and cordierite are used for these purposes. In contrast to cordierite and other silicates, aluminum titanate Al/sub 2/TiO/sub 5/ has a comparatively high melting point 1860 degrees C. This means it can be considered that the compound may be used to obtain ceramics having low alpha values and at the same time quite high service temperatures. The results obtained for specimens prepared by hot pressing confirm the hypothesis about the possibility in principle of creating ceramics from aluminum titanate with higher strength values than are known at the present time. The main approach to solving this problem is to investigate the influence of alloying additives on the microstructure of ceramics made of Al/sub 2/TiO/sub 5/.
