“…Hydroxyapatite (HAp, Ca 10 (PO 4 ) 6 (OH) 2 ), the principal inorganic component in the mammal bone and tooth [2,3], is an osteoconductive material and artificial HAp is viable in the mammalian body over a long period [4][5][6][7]. In contrast, α-alumina (α-Al 2 O 3 ) has high mechanical strength, abrasion resistance, corrosion resistance, and hydrophilicity, supporting its use as an artificial hip joint and artificial tooth root in humans since the 1970s [8]. However, α-Al 2 O 3 is non-osteoconductive [9][10][11].…”

Fibronectin adsorption on osteoconductive hydroxyapatite and non-osteoconductiveα-alumina

The osteoconductivity mechanism of hydroxyapatite (HAp) has not been elucidated. It is hypothesized that specific proteins adsorb on HAp, promoting its osteoconductivity. To verify this hypothesis, we compared the adsorption behavior of fibronectin (Fn) on HAp powder and on α-alumina (α-Al2O3) powder, a material with no osteoconductivity. More Fn adsorbed on α-Al2O3 than on HAp, irrespective of the Fn concentration, and there was no significant difference in the secondary structure of Fn adsorbed on HAp and α-Al2O3. Further, it is possible that Fn did not adsorb on HAp and α-Al2O3 through the Arg-Gry-Asp motif of Fn. The amount of Fn adsorbed on HAp oriented to the a(b)-axis with very little decrease in carbonate and the adsorbed Fn had a smaller α-helix structure content. The results suggest that the secondary and/or higher-order structure rather than the amount of adsorbed Fn might affect the osteoconductivity of HAp, which might be electrostatically controlled by the crystal face orientation and/or carbonate content of HAp, although this should be confirmed by a cell culture test in the future.

“…Alumina is used more frequently for research purposes as one of the most popular oxide ceramic material due to its thermal, electrical and mechanical properties [ 22 , 23 ]. It is widely used in many fields and finding new techniques for fabricating complicated parts in a simple and economical way is very important.…”

Low Temperature Transient Liquid Phase Bonding of Alumina Ceramics with the Bi2O3-ZnO Interlayer

et al. 2022

View full text Add to dashboard Cite

Alumina ceramics were joined by a transient liquid phase (TLP) bonding method at relatively lower temperatures, using mixed powders of Bi2O3 and ZnO with different weight ratios as interlayers between the ceramic components. Bonding was achieved at 750 °C for several of the prepared interlayer mixtures, which makes the applied approach attractive due to the relatively lower joining temperature and potentially low fabrication costs. Measurements by SEM and EDX were used to study the microstructure and chemical analysis of the obtained joints. It also allowed us to investigate the diffusion mechanism occurring in the systems, which resulted in the hypothesis that Zn2+/ZnO diffuses through the ceramics. XRD and Raman spectra were acquired to examine the reaction products that formed during the thermal treatment. The results showed that both ZnO and Bi2O3 react with each other as well as with alumina to form spinel and other products.
