Abstract
A new family of glass-ceramics obtained from muscovite-amblygonite mixtures showing a schiller effect or reflecting surface has been obtained. This effect has not been observed in the bulk material. The raw materials contain about 1% iron as Fe21. In order to elucidate the correlation between surface structure and/or composition and the schiller surface effect, several surface analysis methods, (ESCA, RBS, EPR and reflection Mössbauer spectroscopy) have been used. It seems that a solid solution of Fe31 in the spodumene crystal lattice precipitated from the surface is related to the reflecting effect, which can be controlled by solution of iron oxides in theβ-spodumene solid solution.
