More Information
Summary:A novel fused, cast refractory block (I), with average content of zirconia (i.e. zirconium dioxide plus hafnium dioxide) of more than 85 wt. % (based on oxides), has a standard deviation sigma of the local zirconia content divided by the volume of the block of less than 8 (preferably less than 4). sigma is defined by a mathematical equation given in the specification, utilizing values from samples selected randomly or at locations distributed in (I).
