By means of the method of the spark plasma sintering (SPS) on the basis of nanodimensional powder of nickel oxide (with an average particle size of about 100 nm), the fine-grained (of 250 – 500 nanometers approximately), dense (5.93 g/cm3), strong ceramics with the high microhardness Hv = 8.2 GPa, ultimate compressive strength ?B = 0.4 GPa and Young?s modulus of elasticity E = 140 GPa is created. The obtained ceramic sample was nickel oxide NiO (73-1519) with cubic structure, space group Fm3m (No. 225) and lattice size a = 4.168 ?.
