Abstract

Abstract

The morphology on the surface of hollow glass mircospheres(HGMs) in inflating process was investigated in this work. The experimental results indicate that the main factors influencing the surface of HGM include temperature and pressure, and higher temperature and pressure contributed to the formation of surface morphology. After the appearance of the erosion-like surface morphology, the surface roughness of HGMs increased significantly. However, after some time of storage, the surface roughness of HGMs decreased. The reason for erosion is crystallization and phase separation in essence. The components of crystal mainly consist of the elements of Na and B. The converse transfer of the elements of Na and B causes the decrease of surface roughness of HGMs.
