“…The basic characteristics of used raw materials and obtained high-alumina low cement concrete are given in previously published papers [16][17][18][19][20]. Phase compositions of the concrete depend on sintering temperature and can be predicted by phase diagram C-A (Bogue's notation is applied: C is CaO, A is Al 2 O 3 ) [25].…”

“…Based on authors experience and previously published results [16][17][18][19][20], related to influence of the sintering temperature of low cement high alumina refractory concrete on its behavior under extreme conditions, thermal shock and cavitation erosion, attempt was made to investigate the resistance of this group of materials to effects of the laser beams action. This paper examines degradation of the refractory concrete samples subjected to the low-level laser beam by monitoring the level of degradation: damaged area -pits, as well as pits depth.…”

“…Owing to its excellent properties, especially good thermal stability and chemical stability, alumina (Al 2 O 3 ) ceramic has been widely used in high-temperature environments such as refractory conditions, [13][14][15] thermal barrier coatings, [16][17][18] and nozzles. 19,20 However, the low dielectric loss of Al 2 O 3 limits its application for EM wave absorption.…”

To improve the dielectric and microwave absorption properties of Al 2 O 3 ceramic, Zn-doped Al 2 O 3 ceramic was prepared by conventional ceramic processing. X-ray diffraction analysis confirmed that Zn atoms successfully entered the Al 2 O 3 ceramic lattice and occupied Al sites. The complex permittivity increased with increasing Zn concentration, which is mainly attributed to the increase in charged vacancy defects and densification of the Al 2 O 3 ceramic. In addition, the temperature-dependent complex permittivity of 3% Zn-doped Al 2 O 3 ceramic was determined in the temperature range from 298 K to 873 K. Both the real and imaginary parts of the complex permittivity increased monotonically with increasing temperature, which can be ascribed to the shortened relaxation time and increasing electrical conductivity. The increased complex permittivity leads to a great improvement in microwave absorption. In particular, when the temperature is up to 873 K, the 3% Zn-doped Al 2 O 3 ceramic exhibited the best absorption performance with a maximum peak (À12.1 dB) and broad effective absorption bandwidth (reflection loss less than À10 dB from 9.3 GHz to 12.3 GHz). These results reveal that Zn-doped Al 2 O 3 ceramic is a promising candidate for use as a kind of high-temperature microwave absorption material.
