Iron-magnesium partitioning between ilmenite and spinel

Iron-magnesium partitioning between ilmenite and spinel. Ono, Akira (Natl. Inst. Res. Inorg. Mater., Niihari 305, Japan). Ganseki Kobutsu Kosho Gakkaishi, 78(8), 221-8 (English) 1983. CODEN: GKKGA2. ISSN: 0021-4825. DOCUMENT TYPE: Journal CA Section: 53 (Mineralogical and Geological Chemistry) Fe-Mg partitioning was exptl. detd. as a function of temp., using synthetic chem. homogeneous ilmenite (il) [12168-52-4] and spinel (sp) [1302-67-6]. Solid solns. of the minerals were assumed to be binary regular solns. Isotherms are reasonably explained by the following parameters: Wil = -1. 7439-89-6 and 12168-52-4 are also in the experiment.779T + 8242(J/mol), Wsp = -1.53T + 6142(J/mol), and dG(1) = 2.747T-7632(J), where Wil and dG(1) represent the Fe-Mg interaction parameter in phase il and Gibbs free energy of the exchange reaction (1), MgTiO3 + FeAl2O4 = FeTiO3 + MgAl2O4, resp., at a given temp. and pressure when reaction occurs between end-member minerals, resp. Abs. values of the thermodn. parameters obtained may deviate from the true ones, but these parameters provide a il-sp geothermometer having an accuracy of ±35°. .

Sintering characteristics of magnesium aluminate spinel prepared from precursory solutions by spray drying and calcining

Sintering characteristics of magnesium aluminate spinel prepared from precursory solutions by spray drying and calcining. Jong, B.Some chemicals with cas registry numbers like 10043-01-3 and 13473-90-0 are also used. W. (Georgia Inst. Technol., Atlanta, Ga., USA). Powder Technol., 15(1), 135-7 (English) 1976. CODEN: POTEBX. DOCUMENT TYPE: Journal CA Section: 57 (Ceramics) Section cross-reference(s): 49 Sintering and x-ray diffraction properties of MgAl2O4 spinel [1302-67-6] was studied after prepg. solns. from Mg(NO3)2.6H2O and 2Al(NO3)3.9H2O, 0.5(Mg(NO3)2.6H2O + 2Al(NO3)3.9H2O) and 0.5(MgSO4.7H2O + Al2(SO4)3.18H2O), and MgSO4.7H2O and Al2(SO4)3.18H2O which have pH 1.4, 1.8, and 2.5, and d. 1.135, 1.146, and 1.154 g/cm3 at 25.degree. resp. The sulfate powders increase the sinterability of nitrate powders. Raw materials heated at 1100, 1150, and 1200.degree. for 1 hr produced the activated sintering of MgAl2O4 spinel. .
