In the case of (Zr,W0.06)B2, the WB phase is formed. The formation of homogeneous solid solutions of oxides and diborides was confirmed by transmission electron microscopy. The densification of the obtained powder mixtures to a non-porous state occurred at temperatures of 1900 °C, which is lower than the densification of pure zirconium diboride. The preservation of the diboride-based solid solution after densification is characteristic. The obtained solid solutions had increased high-temperature characteristics such as: oxidation resistance at 1500 °C and high-temperature bending strength at 1800 °C.
