Deformation of nonfired refractories based on phosphate binders. 6. Deformation under heating and creep in corundum composites

Abstract

The results of studying heating deformation and creep are described for two systems: electrocorundum — α-Al2O3 — phosphate binder and electrocorundum — pyrophyllite — phosphate binder. It is shown that composites with H3PO4 experience less deformation than composites with the alumochromium-phosphate binder, whereas using pyrophyllite instead of aluminum oxide increases creep deformation due to the presence of the liquid phase in the material. The effect of technological factors is investigated.
