In this work, copper-doped titanium dioxide (TiO 2 ) nano-powder with of different doping concentration, weights were successfully fabricated with a classical method. This method authorizes obtaining pellets from powder in nonmetric scale with a small quantity. The best conditions for fabrication these pellets are acquired. Different quantities of Cu concentrations (0%, 3%, 5%, and 7%) are mixed with TiO 2 (NPs) nano-particles. Then, the mixed powders are transformed into pellets using hydraulic press and sintered by a traditional furnace at temperature of about 1100 °C. The following apparatus demonstrates the structural, morphological, mechanical, optical properties and the composition of elements of materials for those as-prepared samples: X-ray diffraction (XRD), optical microscope, scanning electronic microscope (SEM), Shore D hardness instrument, roughness test Instrument, Lee’s Disc, Fourier-transform infrared spectroscopy (FTIR) and Energy-dispersive X-ray spectroscopy (EDS) respectively. The effects of Cu doped concentrations on the properties of TiO 2 NPs based on the above instruments are examined. Crystalinality of these materials revealed by XRD patterns and have a grain size between (20-30) nm. A roughness measurement points that TiO 2 NPs values decreases with the addition of Cu weights because of hardness values of the samples. Moreover, results showed that the thermal conductivity increased with the increasing the weight fraction of Cu element. The main goal of the present research is to demonstrate the annealing temperature dependent behavior of the broadening parameter and the properties of Cu doped TiO 2 NPs.
