Comparison of the Properties of the MgO–Y2O3 and MgO–Gd2O3 Ceramic Composites Obtained by the Method of Hot Compaction

Data are presented for comparison of the optical, mechanical, and thermophysical properties of the MgO–Y 2 O 3 and MgO–Gd 2 O 3 ceramic composites consolidated through the hot compaction of the corresponding nanopowders obtained from the glycine-nitrate precursors by the method of self-propagating h...

Description
Summary:Data are presented for comparison of the optical, mechanical, and thermophysical properties of the MgO–Y 2 O 3 and MgO–Gd 2 O 3 ceramic composites consolidated through the hot compaction of the corresponding nanopowders obtained from the glycine-nitrate precursors by the method of self-propagating high-temperature synthesis. It is shown that the MgO–Y 2 O 3 ceramics having a lower density, a higher thermal conductivity, and a larger microhardness, as compared to those of the MgO–Gd 2 O 3 ceramics, is the material of choice for the infrared shielding windows transparent for the radiation with a wavelength falling within the range 3–5 μm.
