Advanced erosion resistant oxide cermets

A cermet composition represented by the formula (PQ)(RS) comprising:

• a ceramic phase (PQ) and a binder phase (RS) wherein,
• P is a metal selected from the group consisting of Al, Si, Mg, Ca, Y, Fe, Mn, Group IV, Group V, Group VI elements, and mixtures thereof,
• Q is oxide,
• R is a base metal selected from the group consisting of Fe, Ni Co, Mn and mixtures thereof,
• S consists essentially of at least one clement selected from the group consisting of Cr, Al and Si and at least one reactive wetting element selected from the group consisting of Ti, Zr, Hf, Ta, Sc, Y, La, and Ce, and
• wherein the ceramic phase (PQ) ranges from of about 55 to 95 vol % based on the volume of the cermet and is dispersed in the binder phase (RS) as particles in the size range of 100 microns to 7000 microns diameter.
