抄録

The relative grinding energy (RGE) and mechanical properties of (Ni0.8Mg0.2)O ceramics were measured. The (Ni0.8Mg0.2)O ceramics have much larger RGE than other ceramics, such as α-Fe2O3 and ZnFe2O4 ceramics with mechanical strength, hardness and KIC similar to those of (Ni0.8Mg0.2)O ceramics. Addition of a small amount of SiO2 to (Ni0.8Mg0.2)O ceramics does not influence the mechanical properties appreciably but lowers the RGE to a great extent. These results were discussed on the basis of the modulus of rupture (MOR) of these ceramics under bending and compressive conditions.
