Abstract
AbstractAluminium reduction cells service life and cell efficiency are strongly influenced by the side wall refractory lining. The aluminum phosphate bonded SiC refractories developed by us, instead of the carbon ones, have increased the cell capacity and productivity by the larger anode surfaces. In order to rank performances of various SiC products were carried out specific laboratory tests. The results of our research concerning materials made from aluminum phosphate bonded SiC showed that they are refractories with a high corrosion resistance and performances close to the bricks made of silicon nitride bonded silicon carbide. By extrapolation of the present study's results we can anticipate an increased service life of electrolysis cells that have such side walls. (© 2009 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
