Abstract:The spectra of CrNaY(which has demolished), CoNaY， NiNaY， CdNaY and CaNaY were investigated. It is suggested that the bands in the rangeof 1 150～1 050 cm-1 and 850～750 cm-1 are assigned to the asymmetric and the symmetric stretching vibration of Si—O—T respectively. It is discovered that the absorption peak arises in the range of 950～850 cm-1 in CoNaY and CaNaYrespectively after CoNaY, NiNaY, CdNaY and CaNaY were heat treated under vacuum.
