摘要: Abstract Cr 2− x Ti O 3+ δ , where varies from 0.1, 0.2 and 0.3 has been prepared by glycerol route characterized powder X-ray diffraction, dynamic light scattering, BET surface area scanning electron microscopy. The thermal expansion coefficient of the samples was studied using a high-temperature diffractometer. bulk dilatometry. An anomaly in ‘ c ’ direction found initially doped which manifested as well at high dopant concentration. anomalies shown these compounds could not be because polycrystalline nature revealed
