| Abstract: | The objective of this work is to study the ceramic material CTO (CaTiO3) by X-Ray Diffraction. The composites of CTO are widely used in dielectric resonators in communication systems. The CTO was prepared by solid state method in a planetary high energy ball milling (Fritsch Pulverisette 5). Stoichiometric quantities of CaCO3 (Aldrich 99%) and TiO2 (Merck 99%) were dry milled during 4h with a rotational speed of 370 rpm and then calcined at 1000 ºC for 3h. After, the CTO was studied by X-ray diffraction (XRD). The refinament showed that the CTO was formed with 100% mass, the graph of Williamson-Hall showed a homogeneous sample, with a contraction in the crystal lattice and a reasonably small particle size. |
