New types of bottom blocks available from the Novosibirsk Electrode Plant Joint-Stock Co. and their performance characteristics

New materials based on electrocalcinated anthracite, gas-calcined anthracite, and artificial graphite (from petroleum coke) have been developed for production of bottom blocks for aluminum electrolyzers at the NovEP JSC. Performance characteristics of the newly-developed materials (density, porosity, compressive and bending strength, elasticity modulus, heat conductivity, resistivity, coefficient of linear thermal expansion and ash content) are discussed and compared to those recommended by DIN international standards.
