Abstract: Spark plasma sintering and a standard free sintering method are used to manufacture ceramic plates with a diameter of 30 mm from aluminum oxide powder with a fraction size approximately equal to 3 $\mu$m. Dynamic strength of the ceramics obtained is studied. Dynamic loading is carried out by a hardened steel impactor. It is shown that energy dissipation in a material obtained using spark plasma sintering is substantially larger than that in a material fabricated using free sintering, which means that it is more resistant to dynamic loads.
Keywords: alumina, oxide ceramics, spark plasma sintering, ballistic tests, hardness, crack resistance.
