“…The mechanical properties of solid materials depend on the tap density of the sample and morphology of the constituent particles. [24] Poorly densified samples include a large number of voids, which can act as starting points for crack formation. [24,25] Both HM-and WM-LGPS pellets exhibited a tap density of 1.63 g cm À 3 under similar contact conditions with the In-Li anode before charge-discharge (Figure S6).…”

“…According to grain boundary strengthening (or Hall-Petch strengthening), materials with a small grain size exhibit high mechanical strength (tensile strength, hardness, and plasticity). [24,25] The yield strength of small-particle materials is enhanced as greater stress is required for dislocation movement in such systems. A small grain size increases the grain boundaries, enhancing the resistance to dislocation pile-up.…”

Stable physical contact between lithium metal/alloy anodes and the solid electrolyte layer is crucial for the durable operation of allsolid‐state batteries. Herein, we have attempted to control the mechanical property of a Li10.35Ge1.35P1.65S12 (LGPS) solid electrolyte layer by the grain size and examined the mechanical strength against stresses originating from volumetric changes of an In‐Li anode layer. The submicron‐sized LGPS electrolyte (d50: 0.51 µm) with a uniform particle size distribution has successfully fabricated by a wet‐milling process. The crystallinity of LGPS hardly changes on pulverization. In‐Li symmetric cells with the wet‐milled LGPS exhibits better cycle stability than those constructed with micro‐sized LGPS (d50: 1.32 µm) that is not well controlled by particle size, owing to a greater suppression of overvoltage generation and growth. Microstructural analyses have revealed that the small and uniform LGPS particles are less prone to physical degradation (cracking) due to volume changes of In‐Li. Downsizing of solid electrolytes is a good strategy for developing physically stable electrode/solid electrolyte interfaces even at high current density operation.

“…It was reported that the largest grain may control the size of largest flaw [217]. Alternatively, grain size can be measured at the fracture origin [218]. The microstructure is affected by multiple factors (e.g., powder impurities, thermal treatments of powders, sieving size), complicating the possibility to understand the role of each factor [24].…”

Toughening of Bioceramic Composites for Bone Regeneration

et al. 2021

View full text Add to dashboard Cite

Bioceramics are widely considered as elective materials for the regeneration of bone tissue, due to their compositional mimicry with bone inorganic components. However, they are intrinsically brittle, which limits their capability to sustain multiple biomechanical loads, especially in the case of load-bearing bone districts. In the last decades, intense research has been dedicated to combining processes to enhance both the strength and toughness of bioceramics, leading to bioceramic composite scaffolds. This review summarizes the recent approaches to this purpose, particularly those addressed to limiting the propagation of cracks to prevent the sudden mechanical failure of bioceramic composites.

“…[72]. In contrast, properties such as coefficients of thermal expansion and electrical conductivity benefit from a coarser grain size [73]. The Plombières tailings are dominantly silt sized, which makes them suitable as a raw material for ceramic production without requiring additional grinding, which lowers the price of production.…”

Geochemical and Mineralogical Characterisation of Historic Zn–Pb Mine Waste, Plombières, East Belgium

Mine wastes and tailings derived from historical processing may contain significant contents of valuable metals due to processing being less efficient in the past. The Plombières tailings pond in eastern Belgium was selected as a case study to determine mineralogical and geochemical characteristics of the different mine waste materials found at the site. Four types of material were classified: soil, metallurgical waste, brown tailings and yellow tailings. The distribution of the mine wastes was investigated with drill holes, pit-holes and geophysical methods. Samples of the materials were assessed with grain size analysis, and mineralogical and geochemical techniques. The mine wastes dominantly consist of SiO2, Al2O3 and Fe2O3. The cover material, comprising soil and metallurgical waste is highly heterogeneous in terms of mineralogy, geochemistry and grain size. The metallurgical waste has a high concentration of metals (Zn: 0.1 to 24 wt.% and Pb: 0.1 to 10.1 wt.%). In the tailings materials, Pb and Zn vary from 10 ppm to 8.5 wt.% and from 51 ppm to 4 wt.%, respectively. The mining wastes comprises mainly quartz, amorphous phases and phyllosilicates, with minor contents of Fe-oxide and Pb- and Zn-bearing minerals. Based on the mineralogical and geochemical properties, the different potential applications of the four waste material types were determined. Additionally, the theoretical economic potential of Pb and Zn in the mine wastes was estimated.
