Pure and Al3+ doped nano-hydroxyapatites (HA) were synthesized by a precipitation method to investigate their densification and thermal stability after the air sintering at 1100 degrees C and 1300 degrees C. Second phases were formed after increasing the All, content from 2.5% to 7.5% in HA and increasing the sintering temperature from 1100 degrees C to 1300 degrees C. Al3+ addition into HA resulted in change in the hexagonal lattice parameters from the pure HA. When the sintering temperature was increased from 1100 degrees C to 1300 degrees C, densification was improved, which was verified by SEM micrographs. Al3+ addition resulted in smaller grain size after the sintering at 1300 degrees C.

Synthesis and characterization of poly(allyl methacrylate) obtained by free radical initiator
Vardareli, Tugba Kantav; Keskin, Selda; Usanmaz, Ali (Informa UK Limited, 2008-01-01)
Allyl methacrylate was polymerized in CCl4 solution by alpha,alpha'-azoisobutyronitrile at 50, 60, and 70 degrees C. The kinetic curves were auto-accelarated types at 60 and 70 degrees C, but almost linear at 50 degrees C. Arrhenius activation energy was 77.5 kJ/mol. The polymer was insoluble in common organic solvents. It was characterized by FT-IR, NMR, DSC, TGA and XPS methods. About 98-99% of allyl side groups were remained as pendant even after completion of the polymerization. The spectroscopic and th...
Borophosphates: Hydrothermal and microwave-assisted synthesis of Na-5[B2P3O13]
Hauf, C; Yılmaz, Ayşen; Kizilyalli, M; Kniep, R (Elsevier BV, 1998-10-01)
Na-5[B2P3O13] was first prepared by high temperature synthesis (T-max = 780 degrees C) and was characterized by X-ray single crystal investigations recently. We have now succeeded in the hydrothermal synthesis of the compound and obtained single-phase products at 150 degrees C after 1-2 days. A microwave-assisted synthesis takes only 2 min to transform a solid mixture of berate and phosphate hydrates into the crystalline title compound. Pure Na-5[B2P3O13] melts at 747 degrees C and solidifies during cooling...
Activity-corn position relations in MuCr(2)O(4)-CoCr2O4 solid solutions and stabilities of MnCr2O4 and CoCr2O4 at 1300 degrees C
Koc, N; Timucin, M (Wiley, 2005-09-01)
Phase equilibria in the system MnO-CoO-Cr2O3 were investigated at 1300 degrees C under controlled oxygen partial pressures by using the gas equilibration technique. The CoO activities in various phase assemblages of the system were measured by determining the partial pressures of oxygen in the gas phase for coexistence with metallic cobalt. The activity data revealed that at 1300 degrees C, MnO-CoO and MnCr2O4-CoCr2O4 solid solutions exhibit mild positive departures from ideal behavior. The activities in th...
Silver and fluoride doped hydroxyapatites: Investigation by microstructure, mechanical and antibacterial properties
Turkoz, Mustafa; Atilla, Aykan Onur; Evis, Zafer (Elsevier BV, 2013-12-01)
Hydroxyapatite co-doped with Ag+ and F- ions was synthesized by the precipitation method and sintered at 1100 degrees C for 1 h. Samples were characterized by density, X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, and scanning electron microscopy to investigate their microstructure, phase formation and bonding characteristics. Moreover, samples were also characterized by microhardness and antibacterial tests. Small amount of dopings resulted in high densities and fine grain...
Synthesis and characterization of conducting copolymers of (S)-2-methylbutyl-2-(3-thienyl)acetate with pyrrole and thiophene
Levent, A; Toppare, Levent Kamil; Cianga, I; Yagci, Y (Wiley, 2003-05-30)
Polymerization of methylbutyl-2-(3-thienyl)-acetate (MBTA) was achieved by constant current electrolysis at low temperature. Subsequently, the syntheses of block copolymers of polyMBTA were accomplished in the presence of either pyrrole or thiophene by constant potential electrolysis. Moreover, the copolymer of MBTA with thiophene was obtained with constant potential electrolysis.
