Solid Solution in the As2S3-Sb2S3 Series at
Orpiment, getchellite and stibnite from Zarshuran deposit, NW Iran, exhibit extensive As-Sb substitution. There are four known minerals along As2S3-Sb2S3 join, i.e. orpiment (As2S3), Wakabayashilite [(As,Sb)20S30], getchellite (AsSbS3) and stibnite (Sb2S3). Extensive mineralogical studies by scanning electron microscope (SEM) and electron probe micro-analyzer (EPMA) indicate that getchellite fr...
متن کاملTHE COMPARISON OF MECHANICAL PROPERTIES OF SINTERED ?. QUARTZ SOLID SOLUTION AND GAHNITE GLASS – CERAMICS IN ZNO-AL2O3-SIO2 SYSTEM
The effect of precipitation of ?.qss. and gahnite phases during heat treatment of glass frits in the ZnO-Al2O3-SiO2 system on the mechanical property of resulting glass-ceramic specimens were investigated. It was shown that gahnite glass-ceramics had higher bend strength and toughness values than ?.qss. ones. The results are attributed to the higher modulus of elasticity as well as higher therm...
متن کاملThermodynamic analysis of nanocrystalline solid solution formation in the W-Co-Si ternary system by mechanical alloying
Co3W2Si intermetallic compound was synthesized by mechanical alloying (MA) of W, Co and Si elemental powder mixtures. The phase composition of the milled products was evaluated by X-ray diffraction (XRD) analysis. Morphological evolutions were characterized by transmission electron microscopy (TEM). The results showed that high energy ball milling performed in the present work led to the format...
متن کاملThe Solid Solution
The monoclinic silicates Lu2SiO5 and Sc2SiO5 (Y2SiO5 type, space groupC2/c) form a solid solution Lu2−xScxSiO5. Samples with x = 0.5, 0.8, 1.0 were synthesized ceramically from Lu2O3, Sc2O3, and SiO2. The structures of three crystals with x = 0.88, 0.77, and 0.50 were refined on the basis of single-crystal X-ray diffraction data. The rare earth (RE) atoms occupy two crystallographically differe...
متن کاملKinetics inversion of chloro-olefine in the solid acid system
The reaction kinetics of the isomerization 3,4-dichlorobutene-1 to 1,4-dichlorobutene-2 was investigated by using gas-liquid chromatography method in the presence of Fe2O3/MgO as solid catalyst in the temperature range 25-55°C. Fe2O3/MgO has been prepared by the support saturation method, tested in the isomerization of 3, 4-dichlorobutene-1 into 1, 4-dichlorobutene-2. This catalyst shows a high...
