Abstract
The thermal expansion characteristics of materials have important influences on their application. There is frequently a need to match the thermal expansion of materials or to improve their thermal shock resistance. Materials with expansion coefficients for such purposes are presently chosen for the most part through a purely empirical approach. This research study has been undertaken to relate thermal expansion characteristics to the crystalline atomic structure arrangement. A previous study by Shirane43 showed that PbTi03, has a negative thermal expansion, over a temperature range where distorted coordination polyhedra about the Pb ions become symmetrical with increasing temperature through better atomic packing. Studies have therefore been undertaken to relate cationic size, structural distortion and thermal expansion properties of particular structural series (M3WO6 and R2Ti05).
