The structures of four tin silicate, SnO–SiO2, glasses have been studied using pulsed neutron diffraction to investigate the environment of Sn2+. The glass structure is based on a tetrahedral [SiO4] network and we find that the mean Si–O distance increases slightly as SnO is added. The ...
1、Go out and buy a pair of glasses, and charge it to us. 去买副眼镜,账记在我们头上。 2、We can arrange this for a small charge. 我们可以将此安排好,只收取很少的费用。 3、控诉:He may still face criminal ...
In this work Mssbauer spectroscopy is used to investigate the oxidation states and structures of tin in silicate glasses. Thermal treatment of the glasses in atmospheres with varying oxygen partial pressure leads to the simultaneous appearance of reduction and diffusion. Experiments with varying ...

The dc conductivity and dielectric parameters of glassy system of a-Se70Te30−x Sn x (x = 0, 2, 4, 6, 8 and 10) glasses have been in
A comprehensive review is given of Mssbauer studies of bond character, electronic structure and glass-crystal transltion in amorphous semiconductors and glasses containing antimony, tin and iron. The isomer shift is correlated with electron density (calculated from HFSCF) at the tin and antimony nucl...
