摘要：
An electrical discharge machinable MgO-Partially Stabilized Zirconia (PSZ) and titanium di-boride (TiB.sub.2) ceramic composite body of good mechanical properties and the method of making it are disclosed. The ceramic composite comprising less than 40% by weight of TiB.sub.2 balanced by 10 mole % of MgO-Partially Stabilized Zirconia is fully densified by pressureless sintering at 1850.degree. C.-1900.degree. C. and exhibits the fracture toughness (K.sub.IC) value of 8-11 MPa.multidot.m.sup.1/2 measured according to the indentation crack length method and Evans-Charles' method provided in Journal of the American Ceramic Society volume 59 �7-8!, 371-372 (1976) after annealing at 1320.degree.-1400.degree. C.
