A SINTERED PRODUCT BASED ON ALUMINA AND CHROMIUM OXIDE

摘要

The invention provides a sintered product presenting an apparent density greater than 4.00g/cmand having the following mean chemical composition, as a percentage by weight based on the oxides and for a total of 100%: AlO-complement to 100%, 16%≤CrO≤29.5%, TiOin a quantity such that the CrO/TiOweight ratio is greater than 16 and less than 35, other species - ≤1%. Application as an electrode bushing block.
