MELT-MOULDED CHROMIUM-CONTAINING REFRACTORY MATERIAL Russian patent published in 2013 - IPC C04B35/657 C04B35/109

Abstract RU 2495000 C2

FIELD: chemistry.

SUBSTANCE: invention relates to the refractory industry and can be used in producing chromium-containing refractory materials for lining glass-melting furnaces when recycling radioactive wastes. The melt-moulded chromium-containing refractory material has components in the following ratio, wt %: Cr₂O₃ 18.0-33.7; Al₂O₃ 24.2-28.0; ZrO₂ 27.0-34.9; SiO₂ 13.1-15.0; MgO 0.3-0.5; B₂O₃ 0.2-0.4; at least one alkaline oxide from the group: Na₂O, K₂O and Li₂O 0.7-1.3; Fe₂O₃ 0.3-0.7; TiO₂ 0.2-0.5; CaO 0.3-0.7.

EFFECT: invention improves manufacturability of refractory articles: melt fluidity and good filling of the mould, as well as high corrosion resistance of refactories in molten borosilicate glass in furnaces for recycling radioactive wastes.
