【Abstract】 In this paper, several common crystallization phenomena caused by alkaline earth metals in the production of fused silica ceramics were introduced, analyzed and summarized. The effects of alkaline earth metals on the crystallization and strength of the materials were analyzed.The element composition and crystal phase of the crystallized materials were tested by atomic absorption and XRD. The reasons for the crystallization on the materials were analyzed and its influences were test. In the end, the effective measures to avoid the crystallization were put forward.更多还原
