WebOne of the most important causes of defective glass is crystallization, which is, after all, the equilibrium stage of the solidifying melt. From this viewpoint, the manufacture of glass is based on tricking the melt so that … WebIt is also called the glass transition temperature or softening temperature. The thermal glass transition is observed when a melt which cannot crystallize is supercooled. The so-called cooperative molecular movements, such as rearrangements of main chain segments, side chain rotations, and end group rotations, then “freeze.”. networkdays include saturday

For example, when silicon dioxide is cooled slowly through the crystallization temperature, it is allowed to form crystals, giving the solid a geometric structure throughout the material. ... WebMar 28, 2011 · Crystallization is a ubiquitous process, producing countless solids in the natural and man-made world.
