On the assumption that the product of volume thermalexpansivity and bulk modulus based on the thermodynamic approximation theory, a new equation is presented for volume thermal expansion coefficient.
In this article, the method of producing the glass from the goldmine-tails has been studied, and the bending strength, chemical stability, density, thermalexpansivity of the glass have been measured.
