Mechanical properties of bovine hydroxyapatite (BHA) composites doped with SiO2, MgO, Al2O3, and ZrO2.
Biologically derived hydroxyapatite from calcinated (at 850 degrees C) bovine bones (BHA) was doped with 5 wt% and 10 wt% of SiO(2), MgO, Al(2)O(3) and ZrO(2) (stabilized with 8% Y(2)O(3)). The aim was to improve the sintering ability and the mechanical properties (compression strength and hardness) of the resultant BHA-composites. Cylindrical samples were sintered at several temperatures betwe...
متن کاملAl2O3/ZrO2/Y3Al5O12 Composites: A High-Temperature Mechanical Characterization
An Al2O3/5 vol%·ZrO2/5 vol%·Y3Al5O12 (YAG) tri-phase composite was manufactured by surface modification of an alumina powder with inorganic precursors of the second phases. The bulk materials were produced by die-pressing and pressureless sintering at 1500 °C, obtaining fully dense, homogenous samples, with ultra-fine ZrO2 and YAG grains dispersed in a sub-micronic alumina matrix. The high temp...
متن کاملInfluence of Si-Doping of Nano-Ni Dispersed Al2O3 Composites on High-Temperature Oxidation
The oxidation kinetics of 5 vol% nano-Ni dispersed Al2O3 with Si-doping (nano-Ni/Al2O3-Si) was studied in the present paper. The starting powder mixture was prepared by drying aqueous slurry consisting of alumina with nickel nitrate and Si (OCH3)4. The powder mixture was reduced at 600 C for 12 h in a stream of Ar-1%H2 gas mixture. Nano-Ni/Al2O3-Si was densified by pulsed electric current sinte...
متن کاملHigh-responsivity SiC Ultraviolet Photodetectors with SiO2 and Al2O3 Films
Silicon carbide (SiC) has shown considerable potential for ultraviolet (UV) photode‐ tectors due to its properties such as wide band gap (3.26 eV for 4H-SiC), high break down electric field and high thermal stability. 4H-SiC-based UV photodetectors such as Schottky, metal-semiconductor-metal (MSM), metal-insulator-semiconductor (MIS) and avalanche have been presenting excellent performance for ...
