Abstract In this study we fabricated, for the first time, magnesium gallate (MgGa 2 O 4 , a partially inverted spinel) transparent ceramics, both undoped and doped with 1 at% Ni. The specimens were derived from in-house prepared powder, crystallite size of ∼10 nm (by wet chemistry) densified by pulsed electric current sintering (PECS; peak temperature 950 °C 90 min). Densification levels 99.84% 99.52% theoretical density attained materials, respectively. Doping Ni was seen to marginally...
Silica glasses have wide applications in industrial fields due to their extraordinary properties, such as high transparency, low thermal expansion coefficient, and hardness. However, current methods of fabricating silica glass generally require long treatment time (up hours) complex setups, leading cost slow manufacturing speed. Herein, obtain high-quality using a facile rapid method, an ultrafast high-temperature sintering (UHS) technique is reported that requires no additional pressure....
Abstract Mixtures of Ce‐doped rare‐earth aluminum perovskites are drawing a significant amount attention as potential scintillating devices. However, the synthesis complex perovskite systems leads to many challenges. Designing A‐site cations with an equiatomic ratio allows for stabilization single‐crystal phase driven by entropic regime. This work describes highly epitaxial thin film configurationally disordered oxide (La 0.2 Lu Y Gd Ce )AlO 3 and characterizes structural optical properties....
Abstract High‐entropy ceramics have been widely explored and extensively studied since the first demonstration of configuration entropy stabilized reversible transitions between multiple single phases by Rost et al. in 2015. Most current research on high‐entropy has focused properties like thermal conductivity, thermoelectricity, structures, others. Some recent studies extended concept to field transparent ceramics. We reviewed these papers proposed four potential groups for including...
Abstract Transparent 1% Gd‐doped YAG and ceramics were synthesized via solid‐state reaction spark plasma sintering using commercially available powder TESO as a additive. The highest in‐line transmission values achieved 77.1% at 550 nm 80.6% 800 in the (at.%) transparent ceramic with 99.90% relative density. Ultraviolet emission 312.5 was observed photoluminescence excitation, making it promising material for applications UV devices.
The use of clean energy is an important part promoting sustainable development. As a source, coalbed methane, during the mining process, position nozzle can influence methane extraction efficiency by affecting cracking effect coal. To investigate impact nozzles on coal fracture, test simulated high-pressure air blasting was executed using 100 mm, 200 and 250 mm from orifice. Based results theories fracture damage mechanics, two models were established for located in middle-upper middle-lower...
Abstract Ti‐doped (0.08, 0.30, and 1.00 atomic% [at.%]) transparent MgGa 2 O 4 ceramics (possessing a high inversion level; i up to 0.8) were fabricated by pulsed electric current sintering, at 950°C, under vacuum for 30–90 min. Optical transmission, emission, electron paramagnetic resonance spectra recorded. The maximal transmission level was ∼70% (820 nm), thickness of ∼1 mm, which, while not very high, permitted the observation optical absorption bands location profile. Interpretation...
Abstract Gallium oxide (Ga 2 O 3 ) has attracted much attention due to its promising applications in optical and electronic devices, while it is difficult fabricate high‐quality Ga transparent ceramics because of the non‐cubic crystal structure. In this work, fully densified undoped rare earth (RE = Tb, Dy. Er)‐doped were successfully fabricated by using spark plasma sintering (SPS) co‐precipitated ceramic powders. Both powders showed pure monoclinic β ‐ structure unique orientation. After...
The low permeability of coal seams has always been the main bottleneck restricting coalbed methane drainage. In this paper, a seam anti-reflection technology with solid-propellant blasting was proposed, and composition proportion solid propellants were determined based on principle oxygen balance. authors designed damage fracture experiment simulation coal, tested impact pressure blast hole wall, measured ultrasonic wave velocity, explosive strain crack propagation then revealed process...
