“…The highest M r (0.15 emu/g) and H c (8.71 kOe) values were observed for this composition. The improvement of M r and H c values for the HAP + 3 vol% CF ceramic was due to the higher amount of CF magnetic phase, which led to higher magnetic performances (inset of Figure 14) in this composition (Jarupoom et al, 2017; Jarupoom et al, 2018; Jarupoom et al, 2019; Jarupoom et al, 2022). The contribution of the paramagnetic host and the magnetic clusters may be a reason for this enhancement.…”

In this research, the bioceramics system of nano-hydroxyapatite-cobalt ferrite or Ca 10 (PO4) 6 (OH) 2 /xCoFe 2 O 4 (HAP/xCF), where x = 0-3 vol%, were studied. The effect of CF concentration on phase evolution, physical, microstructure, mechanical, and magnetic properties as well as the in-vitro apatite-forming ability and cell culture analysis of the HAP ceramic was investigated. XRD revealed that all HAP/xCF ceramics showed high purity of hydroxyapatite with calcium and phosphate. However, the peak of the CF phase is noted for the HAP + 3 vol% CF ceramic. The densification and mechanical properties (HV, HK, σ c , and σ f ) decreased with increasing the CF additive, which correlated to all HAP/xCF ceramics exhibited porous structure with increasing the percentage of porosity. The average grain size also increased with increasing the CF content. An improvement of magnetic behavior, which increasing of the M r , H c , and μ B values, was obtained for the higher CF ceramics. In-vitro apatite-forming ability test suggested that the HAP + 3 vol% CF porous ceramic has a good apatite-forming ability. The cell culture analysis indicated that the proliferation of cells was above 97% for the HAP + 3 vol% CF porous ceramic, which means that the prepared ceramic is biocompatible. Based on the obtained results indicated that these ceramics are promising biomedical application candidates. Research HighlightsWe fabricated the HAP/xCF ceramics by a simple solid-state reaction method. The addition of CF into HAP exhibited magnetic improvement and produced the porous ceramic, which caused good apatite-forming ability. The cell culture analysis indicated that the HAP + 3 vol% CF ceramic is biocompatible.

The composite material of BaFe12O19/ZnO has been fabricated via the solid-state reaction technique with calcination temperature at 900 o C for 4 h. The mixing and the milling processes were conducted using High Energy Milling (HEM) for 3 h in a toluene medium. The optimal condition of the sample BaFe12O19/ZnO was attained with the composition of 50:50 wt%. The XRD analysis revealed the emerging of two phases occurs including BaFe12O19 (the primary phase) and ZnO (the secondary phase). Additionally, the SEM images confirmed that the particles of the composite were granulated with average particle sizes of 3-5 µm. While the VSM examination showed that the Zn addition as a composite material decreased the magnetic properties. Moreover, the I-V measurments showed that nonlinear line increased with the addition of ZnO as a composite material in BaFe12O19/ZnO. Tge optimum magnetic properties was obtained for BaFe12O19/ZnO presented in the following: Ms = 39.91 emu g -1 , Mr = 22.61 emu g -1 , Hc = 2917 Oe, respectively. From the electromagnetic characteristics were obtained that the BaFe12O19/ZnO composite material is suitable for a candidate as the micro-wave absorber.
