They observed that the era of a micro-crack network resulted from the formation of phases with completely different thermal expansion coefficients and the formation and decomposition of the Al2TiO5 after the thermal shock publicity resulted in the next thermal shock resistance 34 Ghasemi et al., studied the effect of the addition of 0, 2, four, 6, and 8 wt. % of Al2O3 micro and nanoparticles on MgO-C refractory ceramic composites sintered at 1650 °C 35 They found that 6 wt. % of alumina nanoparticles promoted the densification of the MgO-C refractory and higher values of cold crushing energy had been obtained with respect to the additions of microparticles as a result of majority presence of MgAl2O4, Al4C3, and AlN phases. In the case of the sample with three wt. % ZrO2 nanopowders, the typical thickness of the layer chemically attacked without the phases of CaZrO3 and ZrO2 was 392 μm, after this level these phases blocked the advance of the slag, see Determine 7 (iii). They discovered that ZrO2 nanoparticles had been simpler than ZrO2 microparticles to extend the densification and hydration resistance of MgO-CaO refractories 19 In other work of the same authors, they reported that adding Fe2O3 nanoparticles to CaO refractories allowed to improve the sintering course of, but they also observed that the resistance to hydration elevated as a result of formation of phases with low melting level (2CaO.Fe2O3, CaO.Fe2O3 and 3CaO.Al2O3) positioned in crystalline defects 20 These low melting point phases have much less tendency to soak up water than free CaO 20 In the identical way, they studied the addition of ZrSiO4 nanoparticles in MgO-C refractories, and so they obtained phases with high oxidation resistance and a dense matrix with small quantity of voids and porosity 21 Shahraki et al. 22 showed that the addition Al2O3 nano and microparticles on MgO-CaO refractories allowed to improve the bodily, mechanical, and thermal properties of the refractory.
