Abstract
In our study of the microstructure of hot-pressed TiB2-x CaB6 specimens we have found that the amount of CaB6 added affects the grain size. The TiB2 g rain size decreases when the CaB6 content in the composite exceeds 5%. The retardation of the grain growth during hot pressing of powder with the comp osition TiB2-10% CaB6 is attributed to dissolution of Ca in it. A composite with that composition has a high microhardness and bending strength.
