Abstract: The present invention provides a fused cast refractory block comprising a mean zirconia (ZrO2+HfO2) content of more than 85% as a percentage by weight based on the oxides, and with a standard deviation ? of the local zirconia content divided by the volume of the block of less than 7.5.

Abstract: A rapid structuring media cartridge includes a cartridge body, a first binder and first abrasive particles. The cartridge is operable to deposit successive patterned layers including the first binder and first abrasive particles to form an abrasive structure.

Abstract: A method of facilitating abrasive article manufacturing includes providing a rapid tooling system to a consumer and providing a cartridge to the consumer. The cartridge has a cartridge body, a first binder and first abrasive particles. The cartridge is configured to operate as part of the rapid tooling system and is operable to deposit the first binder and the first abrasive particles in successive patterned layers to form an abrasive structure.

Abstract: The invention relates to a glassmaking furnace regenerator including a stack of several rows of refractory members defining a plurality of channels, characterized in that the stack comprises, in the hot gas flow direction, a first zone at the hot gas inlet, for rapidly cooling the hot gases, a second zone, or central zone, for condensing and trapping chemical species liable to generate dust, and a third zone, at the cooled gas outlet, for evacuating condensates, the rows of stacked refractory members constituting said central zone including at least two adjacent rows whose channels have a projected surface area at least 20% less than those of the channels of the first and third zones.
