Question

What is the expansion coefficient of glass? Indiabix?

Answer 1

Tensors in Expansion

Tensors can describe these coefficients by accounting for different directions of linear expansion in these anisotropic materials. Cordierite, a silicate materiel that has one positive thermal expansion coefficient and one negative one means its tensor describes a volume change of essentially zero.

Answer 2

it is the expansion that is coefficient to the glass...
