An improved materials transporting element useful for transporting materials in sliding contact with a ware plate, for instance in materials feeder equipment, has a high precision, durable, wear and abrasion resistant sliding surface. The transporting element may have a tetragonal zirconia polycrystal ceramic sliding surface for reciprocal sliding contact with the ware plate having a zirconia-alumina sliding surface. Alternatively, the transporting element may have a zirconia-alumina ceramic composite sliding surface with the ware plate having a tetragonal zirconia polycrystal ceramic sliding surface.
