The development process of the devitrification is featured by a gradual increasing trend from crystallite to skeletal crystal (microlite) and finally to spherulitic.

The alumina bubble is a hollow spherulitic heat-insulating material, which is made by electro-melted method. It is noted for its lightweight, heat-resistance, and close pore.
It was discovered by POM that spherulitic morphology of PHB in the blend changed significantly, size of the spherulites decreased and the secondary crystallization of PHB was inhibited also.
