| Abstract: | Conclusions The possibility of controlling the structure, thus making it possible to obtain thermal-shock resistant materials in the MgO-Cr2O3 system, by combined synthesis and sintering in the same firing, has been studied. The fracture diagrams in load-bend coordinates and the criteria of thermal-shock resistance used to evaluate the tendency of the material to resist the movement of a crack have been studied. An effective composition for a thermal-shock resistant material based on pure magnesium chromite has been obtained.Translated from Ogneupory, No. 8, pp. 44–47, August, 1981. |
