Composites of hydroxylapatite (HA) with pure zirconia, and 3 and 8% Y2O3 in zirconia, were pressure-less sintered at temperatures from 900 to 1300∘C, and hot-pressed at 1200∘C in argon gas atmosphere for 1 h. The reactions and transformations of

In summary, the phase stability in plasma sprayed 8 wt.% PSZ coatings with a porous and cracked microstructure were studied for times of up to 10 000 h at temperatures of 982 °C, 1204 °C, and 1315 °C. The two coatings behaved similarly and exhibit

The ion beam-induced crystalline-to-amorphous transition has been investigated for crystalline phases in the Al2O3–SiO2 system: Al2O3, SiO2 (quartz), Al2SiO5 (kyanite, andalusite, sillimanite), and 3Al2O3⋅2SiO2 (mullite). Xe+ 1.5 MeV was used to

The influence of boron nitride on the coarsening of amorphous silicon nitride was studied by heating mixtures of silicon nitride powder with added boron nitride up to 1600°C. The resulting powders were analyzed with BET surface area measurements, X-

A titanium implant coated with hydroxylapatite was observed after removal from a human jaw. The hydroxylapatite coating and bonded bone were observed in the scanning electron microscope. The bone apatite interface was thinned to electron transparency

Osteoblast, fibroblast, and endothelial cell adhesion on nanophase (that is, materials with grain sizes less than 100 nm) alumina, titania, and hydroxyapatite (HA) was investigated using in vitro cellular models. Osteoblast adhesion was significantly

Ellipsometry, transmission electron microscopy(TEM) and step-profile measurement were used to study the dry oxidation kinetics of silicon at temperatures from 800 to 1100°C. For oxide films thicker than 800 A, all three thickness measurements agreed

Rutherford backscattering spectrometry was used to measure the diffusion constants of bromide in NaCl crystals at temperatures from 20 to 600 °C. For crystals grown from melt at 500 °C and above, our data agree very well with the literature data me
