摘要
The expansion behavior of bubbles in silica glass concerning Czochralski silicon crystal growth has been investigated. It is found that most of the bubbles expand considerably under an Ar atmosphere of 20 Torr and 1500°C. The bubble expansion can be classified into three groups. The first group shows huge expansion which is related to the existence of carbon in the silica glass. In the second group the expansion seems to obey some rule, and most of the bubbles in the silica glass undergo this kind of expansion. The expansion shown by the second group is called normal expansion in this work. The normal expansion depends on the silica material. In the third group some bubbles expand only slightly, and this kind of expansion occurs only near the surface of the glass.
