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. В изобретении предложен спеченный продукт, обладающий кажущейся плотностью более 4,00 г/сми имеющий следующий средний химический состав, выраженный в виде массового процентного содержания исходя из оксидов и в совокупности 100%: AlO- количество, дополняющее до 100%, 16%≤CrO≤29,5%, TiOв таком количестве, что массовое соотношение CrO/TiOсоставляет более 16 и менее 35, другие вещества ≤1%. Применение в качестве изолирующего блока электрода.
