Abstract
Coalescence and crystallization in powdered high‐cordierite glass were investigated by DTA, SEM, and XRD methods, using also thermal expansion and viscosity data. The apparent activation energy for crystallization obtained from the DTA experiments was about half that for viscous flow estimated from the viscosity. Crystallization in such a system is believed to be controlled by a surface nucleation mechanism.
