PROSPECTS FOR USING ALUMINOSILICATE REFRACTORIES FOR ALUMINUM ELECTROLYZERS/PART 1. FEATURES OF THE STRUCTURE OF ALUMINOSILICATE REFRACTORIES INTENDED FOR ALUMINUM ELECTROLYZERS

摘要

Comparative analysis is provided for the structure and properties of aluminosilicate refractories grade ShPD. It is established that refractory ShPD_M-45, produced with the use of an addition of mullite-corundum chamotte surpasses in all characteristics refractories prepared by the normal technology. Refractory ShPD_M-45 may be recommended for use in aluminum electrolyzers.
