IMPROVED COMPOSITION-PROPERTY RELATIONS IN SILICATE GLASSES, PART I: VISCOSITY. Alexander Fluegel, Arun K. Varshneya, David A. Earl, Thomas P. Seward, Dolun Oksoy New York State College of Ceramics Alfred University 2 Pine Street Alfred, NY 14802. ABSTRACT. For the first time, several silicate glass property databases were analyzed without using any a priori knowledge of the details of bonding and lumped as a single group, as a function of the chemical composition. The viscosity of over 300 compositions including soda-lime glasses, borosilicates, glasses with high alkaline earth content, NIST glass viscosity standards, lead silicates, fluorosilicates, and phospho-silicates have been examined. Using multiple regression modeling, linear and multiplicative RELATIONS between the chemical composition and several properties, viscosity, thermal expansion, density, refractive index, electrical conductivity were developed.
K0-K3 in the model equation Eq. (1) are the coefficients, with K0 being the intercept, K1 the single-component coefficients, K2 the coefficients of two …
