Property/structure relationships in lead silicate glasses. Shelby, J. E. (NYS Coll. Ceram., Alfred Univ., Alfred, NY, USA). Glastech. Ber., 56(Int.In this article, certain chemicals are used. One of their cas registry numbers is 1317-36-8 Glaskongr., 13th, Band 2), 1057-62 (English) 1983. CODEN: GLBEAQ. ISSN: 0017-1085. DOCUMENT TYPE: Journal CA Section: 57 (Ceramics) New results of studies on the thermal expansion coeff. and the glass transformation and dilatometric softening temps. of Pb silicate glass (15-70 mol.% PbO) along with literature values were used to produce best value curves for these and other properties of the glass. A change in the structural role of Pb occurs at ~50 mol.% PbO but the effect is not large enough to be statistically significant. .
