Processing mechanical properties and oxidation behavior
Fully dense HfC and TaC-based composites containing 15 vol TaSi 2 or MoSi 2 were produced by hot pressing at 1750–1900 °C. TaSi 2 enhanced the sinterability of the composites and nearly fully dense materials were obtained at lower temperatures than in the case of MoSi 2-containing ones.The TaC-based composites performed better than HfC composites at room temperature showing values of

RefractoriesAn Overview
Feb 14 2001 · RefractoriesAn Overview. Refractories are ceramic materials capable of withstanding high temperatures. The bulk of refractory materials consist of single or mixed high melting point oxides such as silicon aluminum magnesium calcium and zirconium. Non-oxide refractories also exist and include materials such as carbides nitrides borides

Feb 10 2020 · The existence of nano‐alumina could promote more calcium dialuminate (CaO·2Al 2 O 3) and CA 6 (CaO·6Al 2 O 3) formation at lower temperatures.The addition of nano‐alumina is beneficial to form more platelet CA 6 at 1500℃ which improved the hot and cold strength of castables. The platelet CA 6 created excellent bonds between particles in the body by an interlocking morphology.
