Abstract Molecular complexes of tin tetrachloride with some aliphatic compounds, such as alcohols and esters, were investigated by means of the Mössbauer effect due to 119Sn, irradiation being made by 23.8 keV γ-rays from the 119mSn in tin dioxide. Most of these complexes show quadru-pole splittings resulting from the addition of organic molecules to tin tetrachloride, although broad absorption curves are observed in some cases. The isomer shifts range from 0.30 to 0.45 mm/sec. They are much smaller than that of tin tetrachloride itself. The results are interpreted by taking account of the electronic structures of the complexes.

The preparation of hyper‐pure silicon by reduction of silicon tetrachloride with zinc vapor is described. This reaction, which takes place at 950 C, was carried out in apparatus constructed of fused silica. The silicon prepared by this process was essentially spectrographically free of metallic impurities, and had extremely low electrical conductivity.

Abstract A new method has been devised for the estimation of silicon in silicon tetrachloride. It is based on a quantitative esterification with absolute ethyl alcohol, the silicon content of the resulting ester being estimated.

Abstract Abstract The γ-radiolysis of hydrogen sulphide in the presence of : utadiene and carbon tetrachloride was studied. Addition of butadiene causes the slow diminishing in G(H2) and sharp lowering in G(S) from 7.1 for pure H2S down to 0.8 at all the used concentrations of butadiene. When carbon tetrachloride is added to hydrogen sulphide, G(H2) is not changed but G(S) increases by ΔG(S) ≈ 2. The presence of butadiene and carbon tetrachloride together allows to the same change in G(H2) as in the case of butadiene alone and lowering I(S) to zero. The ionic mechanism of molecular sulphur formation is proposed, consistent with the observed experimental facts.

High-temperature (>500 °C) chlorosilane gas streams are prevalent in the manufacture of polycrystalline silicon, the feedstock for silicon-based solar panels and electronics. This study investigated the influence of metallurgical grade silicon on the corrosion behavior of pure iron in these types of environments. The experiment included exposing pure iron samples at 600 °C to a silicon tetrachloride/hydrogen input gas mixture with and without embedding the samples in silicon. The samples in a packed bed of silicon had significantly higher mass gains compared to samples not in a packed bed. Comparison to diffusion studies suggest that the increase in mass gain of embedded samples is due to a higher silicon activity from the gas phase reaction with silicon. The experimental results were supported by chemical equilibrium calculations which showed that more-active trichlorosilane and dichlorosilane species are formed from silicon tetrachloride in silicon packed bed conditions.
