Anew constant-volume high-alumina bonite filler has been created on the basis of calcined slag formed in the production of metallic chromium. Calcining the slag at different temperatures increases its content of calcium hexaaluminate CaO6(Al,Cr)2O3 from 55 - 60 to 70% (calcination at 1450 C) and 90% (calcination at 1650 C). New compositions have been found for low-cement concretes based on the chromium-bearing bonite filler. © 2013 Springer Science+Business Media New York.

A technology is described for making a heat-insulating bonite (hexaaluminate) filler based on a high-alumina material (a recycled catalyst support) and high-alumina cement. The properties of the filler and heat-insulating concretes made with it are also described. The concretes are distinguished by their high strength and deformability, low thermal conductivity, and minimal shrinkage up to 1450°C. They can be recommended for use in high-temperature thermal insulation. © 2014, Springer Science+Business Media New York.
