A study has been made of the microstructure of chromite spinel and its changes in basic refractory brick under service conditions. Part of the changes occurring resemble those described previously for slag‐free environments, frequently enhanced by extended periods of exposure. In addition, slagging by solid, liquid, and vapor phases produces interesting new spinel micro‐structures in open‐hearth furnace roofs and checker systems, in various furnaces of the copper industry, in rotary kilns and glass‐tank checkers, and in regenerator walls.
