                         barrier at high temperatures. Thermal barriers on metallic 
                         substrates of aircraft turbine fans are used to increase the 
                         turbine{\^a}s temperature and thus generates a better combustion 
                         that improve their performance and reducing their consumption. So, 
                         the emission of pollutants such as CO and CO2 also decrease, which 
                         justifies the use of zirconia as a material for environmental 
                         protection. This work aims the application of zirconia with 
                         equimolar addition of yttrium and niobium oxides, as a thermal 
                         barrier. Different routes to obtain this material were analyzed. 
                         Samples were obtained with equimolar additions of 14.5, 16 and 
                         17.5%, using planetary mill. These samples were sintered in air 
                         and in vacuum at 1500, 1550, 1600 and 1650°C. After sintering, the 
                         samples were characterized by measurement of specific mass, 
                         Vickers hardness and fracture toughness. The results showed that 
                         the samples sintered at 1600 and 1650°C in vacuum have improved 
                         hardness and fracture toughness behavior, which are important to 
                         improve the wear resistance.",
