Cutting ceramic composition: 1 - aluminum oxide (Аl2О3); 2 - refractory metal carbides (TiС, WC, MoC) The main factors affecting the cutting properties of ceramic cutting inserts are the microstructural parameters of the material, which include the number, distribution pattern and size of carbide inclusions.
The more ceramic grains are distributed over the area of ceramic plates and the smaller their size, the better the cutting properties and performance of the tool material [1-3].
Result and Discussion Studies have shown [1] that ceramic plates with the smallest diameters and with the largest number of carbide grains distributed over the area have a higher electrical resistance (about 100 Ω), and ceramic plates with the smallest diameters and with the least amount of carbide grains distributed over the area have lower electrical resistance (about 10 Ω).
As can be seen from the applied materials (Fig. 5), for ceramic specimens with an electrical resistance close to R = 100 Ω, the distribution of carbide grains is larger over the area and their size is smaller than for ceramic specimens with an electrical resistance close to R = 10 Ω.

Changes in macrostructure resulting from repeated thermal shocks were studied and a decrease in both the number and size of intergranular and intragranular interlacing fractures was observed [8]; this is the so-called self-healing effect.
Figure 3 demonstrates the change in flexural strength of doped AT samples as a function of number of thermal shock cycles.
After the 10 th cycle this process reverses and more and larger fractures develop in the structure, which reduces strength inevitably. 0 5 10 15 20 25 30 35 0 5 10 15 20 25 30 35 40 45 number of cycles flexural strenght AT ATF05 ATF1 ATF2 ATF3 ATF5 Fig. 3 Change in flexural strength of Fe2O3 doped AT samples as a function of number of thermal shock cycles Morphological analyses were performed to support the results of strength tests.
Individual grain sizes vary in the range of 40-60 µm.
In the electron microscope image taken after the 10 th cycle (Figure 5) no further structural degradation can be detected, on the contrary, the number of fractures in the sample decreased and there are smaller and allied grains (with size about 10-30 µm).

A series of CoFe2-2xZrxMnxO4 (0.10.4) spinel ferrite samples are prepared by the chemical co-precipitation method [6] and the changes in a number of parameters, namely, lattice parameter, porosity, X-ray density and bulk density have been reported.
The theoretical density was calculated using the formula (5) where 8 stands for the number of formula units in a unit cell, N is the Avogadro’s number, M is the molecular weight of the one formula unit and V is the volume of the unit cell.
The resistivity of the ferrites in general, depends on different factors such as the density, porosity, grain size etc.
n =NADmPFe / M (7) where NA, Dm and M are the Avogadro’s number, mass density and molecular weight of the corresponding sample, respectively and PFe is the number of iron atoms in the formula CoFe2-2xZrxMnxO4 (0.10.4).
