“…[38][39][40] In recent years, the development of high-entropy ceramics (HECs) has provided a good opportunity for improving the performances of ZrB 2 -based ceramics by designing multicomponent solid solutions at atomic level due to high entropy effect, lattice distortion effect, sluggish diffusion, and "cocktail" effect. [41][42][43] The enhanced hardness, [44][45][46] thermal, 47,48 oxidation, [49][50][51] corrosion, 52,53 and irradiation resistance 54,55 can be found in reported high-entropy carbides, 56,57 nitrides, 58,59 borides, [60][61][62] oxides, 63,64 or silicides. 65,66 However, open reports are mainly focused on the preparation and properties of HECs with an equimolar ratio.…”

Zirconium diboride ceramics as one of the main members of ultrahightemperature ceramics are capable of being used as structural components at ultrahigh temperatures. Entropy adjusting is a newly developed approach to improving the properties of ceramics. In this work, a series of ZrB 2 -based solid solution ceramics with different mixing entropies, formulated (Zr x Ti y Nb y Ta y )B 2 (x = .25, .85, .925, .9625, 1; x + 3y = 1), were prepared by adjusting the content of other diborides. Diboride solid solution powders were synthesized by boro/carbothermal reduction process and then densified by spark plasma sintering. The results show that the formation of a single-phase solid solution is independent of the mixing entropy in (Zr x Ti y Nb y Ta y )B 2 system. The addition of other diborides into ZrB 2 is beneficial to reduce the particle size of the synthesized powder and promote the densification process. The dense sintered samples with higher mixing entropy have finer grain size, higher hardness, and modulus. The (Zr 0.25 Ti 0.25 Nb 0.25 Ta 0.25 )B 2 ceramic has the highest hardness of 31 GPa and a modulus of 682 GPa. Severe lattice distortion in samples with higher mixing entropy will result in increased phonon scattering and lower thermal conductivity.

“…In crystalline materials, this suggests that the migration length of the non-equilibrium carriers formed by ionizing radiation decreases, and the probability of the carriers reaching the emission centers increases, resulting in faster decay and a higher LY [216,217]. Recently, a novel term for the multicomponent garnets has also been referred to as high-entropy ceramics [218]. This is a broader meaning of the high-entropy ceramics, which is not quite the same as the traditional highentropy ceramics in Ref.…”

View full text Add to dashboard Cite

Garnet ceramic scintillators are a class of inorganic scintillation materials with excellent overall performance. The flexibility of cation substitution in different lattice positions leads to tunable and versatile properties and a wide range of applications. This paper starts with an overview of the development history of the inorganic scintillation materials, followed by a description of major preparation methods and characterization of garnet scintillation ceramics. Great progress obtained in recent years consisting in applying the band-gap and defect engineering strategies to the garnet scintillation ceramics is reviewed. Finally, the respective problems in the preparation and performance of multicomponent garnet single crystals and ceramics and the effective solutions are discussed. The garnet scintillation ceramics with the highest application potential are summarized, and the future development directions are proposed.

The review is devoted to the analysis of the compositional disordering potential of the crystal matrix of a scintillator to improve its scintillation parameters. Technological capabilities to complicate crystal matrices both in anionic and cationic sublattices of a variety of compounds are examined. The effects of the disorder at nano-level on the landscape at the bottom of the conduction band, which is adjacent to the band gap, have been discussed. The ways to control the composition of polycationic compounds when creating precursors, the role of disorder in the anionic sublattice in alkali halide compounds, a positive role of Gd based matrices on scintillation properties, and the control of the heterovalent state of the activator by creation of disorder in silicates have been considered as well. The benefits of introducing a 3D printing method, which is prospective for the engineering and production of scintillators at the nanoscale level, have been manifested.
