Conclusions
Laboratory and industrial experiments confirm the possibility of producing high-alumina products using Troshkov clay. The experimental brick (about 62% Al2O3) made from Troshkov clay and calcined alumina, prepared by the technology involving the use of high-chamotte refractories and fired at 1520°C, possesses equivalent or higher properties than the same products based on Latnensk.
The high-alumina bond containing Troshkov clay is inadequately sintered with the grains of chamotte. In order to obtain more densely sintered products it is necessary to increase the content of fine fractions of the components (<0.063 mm) in the bonding part of the batch during their combined grinding, or to increase the firing temperature of the brick.
