Abstract
Co-efficient of linear thermal expansion of the glass-forming oxides has been calculated
/rnm the following equation derived earlier1

x=SCpyZ

where Cp is the heat capacity, E the crystal energy, n the Born constant and Z is the
average ionic valency. The calculated values of ':1.. /or the different glass-forming oxides
are in agreement with the empirical additive /actors /or calculating thermal expansion
of glass, suggested earlier2
