The 1:1 compound, CeAlO3, in the system Ce2O3-Al2O3 has been synthesized from the oxides and shown to have a perovskite-like tetragonal unit cell with the lattice parameters a = 3.763 and c = 3.792 Angstrom. A new XRD pattern is suggested for CeAlO3. This compound is shown to be stable up to 1950 degrees C. The 1:11 compound, CeAl11O18, has also been synthesized and shown to possess a magnetoplumbite-like hexagonal unit cell with the lattice parameters a = 5.558 and c = 22.012 Angstrom. An XRD pattern is suggested for CeAl11O18 for the first time. The evolution of eutectic-like microstructures was observed and reported in the Ce2O3-rich side of this binary system.

Kinetic model for alpha-tricalcium phosphate hydrolysis Durucan, Caner (Wiley, 2002-08-01) A mechanistic model for the kinetics of hydrolysis of alpha-tricalcium phosphate (alpha-Ca-3(PO4)(2) or alpha-TCP) to hydroxyapatite (Ca10-x(HPO4)(x)(PO4)(6-x)(OH)(2-x) or HAp) has been developed. The model is based on experimental hydrolysis rate data obtained using isothermal calorimetry. Analysis of the kinetic data according to the general kinetics models in terms of the fractional degree of reaction and time suggests the hydrolysis to be controlled by different rate-limiting mechanisms as reaction proc...
PHASE-RELATIONS IN THE SYSTEM CE2O3-CE2SI2O7 IN THE TEMPERATURE-RANGE 1150-DEGREES TO 1970-DEGREES-C IN REDUCING AND INERT ATMOSPHERES TAS, AC; AKINC, M (Wiley, 1994-11-01) The high-temperature phase relations in the system Ce2O3-Ce2Si2O7 have been studied in the temperature range 1150 degrees-1970 degrees C in inert and reducing atmospheres by conventional quenching and differential thermal analysis. Three eutectic reactions were found to occur at 1664 degrees C and 27 mol% SiO2 between Ce2O3 and Ce2SiO5, at 1870 degrees C and 54 mol% SiO2 between Ce2SiO5 and Ce-4.67(SiO4)(3)O, and at 1762 degrees C and 65 mol% SiO2 between Ce-4.67(SiO4)(3)O and Ce2Si2O7. Microstructural char...
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...
Synthesis and characterization of conducting graft copolymers based on oligophenols Sahmetlioglu, Ertugrul; Arikan, Ufuk; Toppare, Levent Kamil; Yuruk, Huseyin; Mart, Hasan (Informa UK Limited, 2006-10-01) Oligo-2-aminophenol (OAF) was synthesized with oxidative polycondensation of 2-aminophenol and hydrogen peroxide in an aqueous alkaline medium at 80 degrees C. Oligo-2-aminophenol with thiophene side groups (TOAF) was obtained by the reaction of OAF and thiophene-3-acetic acid. Graft copolymers of TOAF and pyrrole were synthesized by electrochemical polymerization in p-toluene sulfonic acid (PTSA)/water medium. Characterization of the graft copolymer (TOAF-g-Py), was carried out by combination of techniques...
ACTIVITY COMPOSITION RELATIONS IN NIAL2O4-MNAL2O4 SOLID-SOLUTIONS AND STABILITIES OF NIAL2O4 AND MNAL2O4 AT 1300-DEGREES-C AND 1400-DEGREES-C TIMUCIN, M; MUAN, A (Wiley, 1992-06-01) Activities of NiO were measured in the oxide and spinel solutions of the system MnO-NiO-Al2O3 at 1300-degrees and 1400-degrees-C with the aim of deriving information on the thermodynamic properties of the spinel phases. Synthetic samples in selected phase assemblages of the system were equilibrated with metallic nickel and a gas phase of known oxygen partial pressures at a total pressure of 1 atm. The data on NiO activities and directions of conjugation lines between coexisting oxide and spinel phases were ...
