“…At the same time the small particles with critical size disappear contributing to the growth of larger grains [39]. The results in the present study are in agreement with previous work done on HA [40,41].…”

“…The diametral tensile stress (DTS) test can be alternatively used to evaluate the flexural bending test and is particularly preferred for bone and dental biomaterials. This is because the stress produced invivo for bone and dental implants is similar to that performed in the DTS test [40]. The DTS values of the Ca 2 MgSi 2 O 7 disks sintered at 1200, 1225 and 1250 °C for 6 h were found to be 6.58 ± 0.34, 12.39 ± 0.52 and 13.70 ± 0.66 MPa, respectively.…”

Akermanite (Ca2MgSi2O7) ceramic powders were prepared by a wet solid-state synthesis process using a mixture of oxide sources. The mechanism of phase formation included the formation of transition compounds such as diopside and merwinite. The compacted disks of the dried mixture were sintered at 1200, 1225 and 1250?C for different dwell times (2, 4 and 6 h). The effect of sintering temperature on the physical properties (relative density and diameter shrinkage), grain growth kinetics (grain growth activation energy) and mechanical properties (flexural strength) of the akermanite ceramics were evaluated. It was shown that the increase in sintering temperature from 1200 to 1250?C decreased the porosity and increased the diameter shrinkage and relative density of Ca2MgSi2O7 ceramics. The grain growth activation energy was also found to increase with the increase of sintering temperature. Finally, the increase in density yielded ceramics with high mechanical strength.

“…When we increased the F value in the fixed group of the La value, this increase was 5%, after which a decrease was obtained. Due to regularly shaped particles expected from the morphological evaluation (Turkoz & Erdem, 2019;Chen et al, 2018;Toker et al, 2011;Uysal et al, 2014;Yedekçi et al, 2021). However, the result is obtained that the powders produced consist of particles with nano-size.…”

Hydroxyapatite (HA) co-doped with La 3+ and F À ions were synthesized by the precipitation method and sintered at 1,100 C for 1 hr. Samples were characterized by the standard experimental methods including the density, X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM) to investigate their microstructure, phase formation, and bonding characteristics in detail. Moreover, the materials produced were identified using the microhardness tests. It was observed that in the most of materials, the hydroxyapatite was found to be the main phase with a minor amount of β-tricalcium phosphate (β-TCP).Furthermore, the presence of fluoride and small amount of β-TCP was verified with all the characteristic FTIR bands of hydroxyapatite for the majority of samples studied. The result in SEM evaluation is that the produced HA powders have less deformed, uniformly distributed, and regularly shaped particles. Here, the material density has changed towards a less dense state with the increasing rate of La doping, but statistically significant difference was not obtained (p, .1942 > .05) with increase

“…Bone healing is a well-orchestrated process involving interactions among different complex biological events, including early inflammatory immune regulation, angiogenesis, osteogenic differentiation, and osteogenesis [ 5 , 6 ]. Various biomaterials have been investigated, with emphasis on the development of favorable bone substitutes with desired physiochemical [ 7 , 8 ], mechanical [ 9 , 10 ], and osteogenic properties [ 11 , 12 ] related to bone formation. However, the often-ignored regulatory role of the immune system in the biomaterial-mediated bone microenvironment can lead to undesirable bone repair effects [ 13 ].…”
