Density of Glass Melts

For description of the expansion of solids as well as highly viscous melts (for example, in the glass transition regions) linear thermal expansion coefficients

α

are

used. In this case, in equations (1) and (2), values

V

are replaced by values

L,

which describe any linear dimension of the studied body. For small expansion coefficients

β

α
