A cermet composition represented by the formula (PQ)(RS)Xcomprising: a ceramic phase (PQ), a binder phase (RS) and X wherein X is at least one member selected from the group consisting of an oxide dispersoid E, an intermetallic compound F and a derivative compound G wherein said ceramic phase (PQ) is dispersed in the binder phase (RS) as particles of diameter in the range of about 0.5 to 3000 microns, and said X is dispersed in the binder phase (RS) as particles in the size range of about 1 nm to 400 nm.
L'invention a trait à une composition de cermet représentée par la formule (<I>PQ</I>)(<I>RS</I>)<I>X</I>, qui contient une phase céramique (<I>PQ</I>), une phase liante (<I>RS</I>) et <I>X</I>, <I>X </I>représentant au moins un élément sélectionné dans le groupe formé par un dispersoïde d'oxyde <I>E</I>, un composé intermétallique <I>F </I>et un composé dérivé <I>G</I>. Ladite phase céramique (<I>PQ</I>) est dispersée dans la phase liante (<I>RS</I>) sous forme de particules dont le diamètre est compris entre 0,5 et 3000 microns, et <I>X</I> est dispersé dans la phase liante (<I>RS</I>) sous forme de particules dont la taille est comprise entre 1 et 400 nm.
