High-temperature zirconium-dioxide binders for the masonry of the outer trap of a reactor

Investigations were performed for the purpose of selecting the compositions of zirconium dioxide binding materials (mortars) wit two types of binders: barium monoaluminate and zirconium dioxide binding suspension. The foundat ions of a technology for obtaining these material sand their applications w ere developed and the density, porosity, contraction, and behavior in conta ct wit steel and iron oxide melts were described. The mortars developed wer e recommended for use in a refractory shielding of the outer trap based on zirconium dioxide heat-resisting materials.
