Effect of Mechanical Activation of Iridium on Its Reaction with Refractory Carbides
— We have studied solid-state reactions of unmilled and ball-milled iridium powders with SiC and WC powders in the temperature range 800–1400°C. Interaction of iridium with SiC leads to the formation of various iridium silicides, whose composition and concentration depend on the reaction mixture tre...

intermetallic phase with a broad homogeneity range. Mechanical treatment of iridium powder has been shown to markedly speed up solid-state reactions between the iridium and refractory carbides, primarily owing to the associated increase in the specific surface area of the iridium and the accumulation of structural defects. |
