Glass Type – Alkaline Earth Boro-Aluminosilicate Thermal Conductivity
Forms Available – Fusion drawn sheet
Principal Uses – Substrates for Active Matrix flat Thermal Conductivity is a calculated value, and is equal
panel displays to the product of the Thermal diffusivity multiplied by
Specific Heat multiplied by Density of the glass.
Corning 1737 is available in both, standard and arsenic-
