Abstract Iron oxide/titania composites were synthesized by precipitation method. Amount of iron oxide was varied in the composites. The single phase (anatase) was obtained for the weight ratio of 0-20% and three phases (anatase, magnetite and hematite) were found for the weight ratio of 30% and 40% of iron oxide. The crystallite size of titania decreased with increasing of iron oxide content. The specific surface area, total pore volume and BJH pore volume of the sample increased with increasing iron oxide content in the composite. The composites possessed mesoporous characteristic (6.5-9.6 nm in pore diameter) and exhibited ferromagnetic properties. The measurement of the microwave absorption showed that the 40Fe/Ti composite had the best reflection loss of -14 dB at a frequency of 10.9 GHz. This meant that the electromagnetic wave was absorbed 80% in that frequency. Thus, the developed material can be a promising microwave absorbing agent in radar signature reduction.

The objectives of this study were to prepare leadless crystalline glazes from iron oxide by using low temperature firing (1,100°C) and to study the effect of concentration of iron oxide on the phase composition of the glaze raw materials on phase transformation in leadless iron oxide crystalline glaze. The crystalline phases were investigated by using the DTA, X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The composition of the glaze raw materials compose of nepheline syenite, colemanite, pottery stone, bentonite, ZnO, Li2CO3, SiOSubscript text2 and 10, 15 and 20%(w/w) iron oxide (Fe2O3). The glaze raw materials were ground for homogeneous mixtures by ball milling for 24h. The average particle size of the mixture was 3.86 µm. The glaze bodies were carried to firing at 1,100°C at the heating rate of 2°C/min and soaking for 0.5h. Then, the glaze bodies were cooled at the cooling rate of 1°C/min and maintained at 1,080°C for 3h and then maintained at 980°C for 1h, respectively. From the experiment results, it was found that the crystallization temperatures (Tc) of franklinite (ZnFe2O4) and anorthite (CaAl2Si2O8) depend on the concentration of iron oxide content.

The chromite deposits of the Fiskenæsset region occur in anorthosites, which together with intercalated pyribolites (hypersthene amphibolites) and subsidiary pyroxenites and peridotites occur in the gneisses as horizons belonging to a folded and metamorphosed stratiform complex which has a maximum thickness of 2 km. The chromite occurs in horizons which average 0.5 - 3 m in width, reaching a maximum of 20 m, and consist of alternating anorthosite and chromitite layers, usually between 0.5 and 10 cm wide. Chromite horizons occur in almost all of the anorthosite horizons in the region which have a minimum exposed length of 125 km. 175 X-ray fluorescence analyses show that the Cr2O3 content of the chromite varies between 26% and 36%, averaging 32.7%. The total iron oxide content varies between 28% and 42%, averaging 31. 8% (as FeO), with the result that the Cr:Fe ratio varies between 0.66 and 1.05, averaging 0.93. The chromite has a high V2O5 content varying from 0.2% to 0.5% with an average value of 0.3%. The chromite horizons occur along the shores of the fjords or only a few kilometres from the coast in easily accessible terrain that rarely exceeds 500 m in altitude. Fiskenæsset harbour is ice-free for the whole year.
