https://doi.org/10.17073/1683-4518-2018-10-31-36
Abstract
The heterogeneous CaB6‒TiB2 powder blends were synthesized by means of the TiO2 and CaCO3 mixture boron carbide reduction under vacuum at 1400‒1650 °C, and reactive hot pressing was used according to the condition: 1500 °C (synthesis in vacuum) ‒ 1900 °C (Argon pressing). As a result of the CaB6‒TiB2 synthesis with the mass ratio 1:1 at 1600 °C and isothermal time 1 hour the heterogeneous mixture was prepared which contained the CaB6 and TiB2 crystal phases as well as the residual B4C admixture (0,5 mass percent). The powder particles were the grains 1‒3 micrometers in diameter containing two phases CaB6 and TiB2 as the micro crystals 0,1‒1,0 micrometers in diameter uniformly spaced over the particle volume.Ill. 6.
