Conclusions
A study of the contact reaction of bakor and chamotte refractories showed that at 1250°C a contact zone is formed consisting of glass and needle crystals of mullite. With rise in the temperature of heat treatment, mullitization is increased as a result of the dissolution of grains of chamotte and corundum in the glass, with subsequent crystallization of mullite from it. Starting at 1350°C the glass penetrates deeply from the glassy zone into the chamotte and bakor refractories, reacting with their glass phase. As a result of this the composition of the glass phases of both materials in the contact zone is evened out. At 1600°C we note the presence of a small amount of newly formed zircon.
