Abstract (en)

[origin: WO9912864A1] A molding compound is used to form net-shape or near net-shape articles consisting essentially of about 50 to 100 wt.% ZrO2(Y2O3) and 0 to about 50 wt.% Al2O3. The compound, containing ceramic powders having an average particle size less than 1 mu m, is mixed with a liquid carrier, a gel forming binder and processing additives and can be molded at relatively low pressures in a conventional injection molding machine.
