“…Sintering is a one-way processing technique which allows the production of density-controlled materials and components from metal or/and ceramic powders through particle bonding. This process of powder consolidation is quite famous and has been applied in different fields for more than 5000 years [1][2][3][4].…”

“…Concerning an effect of the aid on the ceramics densification, a possible phase transformation at the sintering temperatures can provide a significant amount of defects and accelerate mass transfer. Such an approach demonstrated its effectiveness in the case of YAG transparent ceramics [28, 29, 30, 31, 32, 33]. On the other hand, relatively low transition temperature at phase equilibrium point in the La 2 O 3 -Ho 2 O 3 system, when the ions diffusion is slow, can lead to the preservation of the second phase in the ceramics.…”

Weakly agglomerated nanoparticles of (Ho 1-x La x ) 2 O 3 solid solutions were synthesized with the help of a self-propagating high-temperature synthesis (SHS). The nanopowders were studied by a simultaneous thermal analysis (TG-DSC), X-ray diffraction (XRD), BET and FT-IR spectroscopy methods. Changes of the particles morphology after annealing at different temperatures and ball milling were investigated by a scanning electron microscopy (SEM) and a dynamic light scattering (DLS) method. It was found that annealing at a temperature of 900 °C in air and ball milling of the SHS nanopowders allow obtaining rounded shape particles with a mean diameter of about 20 nm and C-type cubic crystal structure. Up to 10 mol.% of the lanthana was shown to dissolve in the holmium oxide nanoparticles.

Transparent cubic‐phase solid solution (Ho1–xLax)2O3 (where x = 0, 0.03, 0.05, 0.07, and 0.1) ceramics are sintered in a vacuum at 1780 °C for 3 h from nanopowders made by self‐propagating high‐temperature synthesis. The lanthana is proved to significantly influence the microstructure of the ceramics. The average crystallite sizes of the (Ho1–xLax)2O3 ceramics decrease with an increase in the concentration of lanthana. After vacuum sintering and low‐temperature annealing in air, the ceramics have second‐phase grains at the crystallite boundaries and the triple points. The volume fraction of the second phase is found to be in direct proportion to the lanthana content in the ceramics. This second phase is believed to be (Ho1–xLax)2O3 solid solutions with a higher lanthanum content in comparison with the surrounding crystallites. Annealing of the ceramics at 1500 °C for 2 h leads to the elimination of the second phase.
