氧化铝玻璃复合体与Vita alpha饰瓷匹配性的研究

Research on the matching between alumina glass composite and Vita alpha veneering ceramic

目的 考察作者自制的氧化铝玻璃复合体与Vitaalpha饰瓷的匹配性。方法 采用热冲击试验与扫描电镜观察 ,分析研究氧化铝玻璃复合体与Vitaalpha饰瓷的匹配性。结果 抗热冲击温度ΔT平均为 170℃ ;扫描电镜观察结果显示Vitaalpha饰瓷与氧化铝玻璃复合体结合紧密 ,界面实现了瓷 瓷融合。

Objective To investigate the matching between selfmade alumina glass composite and Vita alpha veneering ceramic. Methods By using thermal shock test and SEM. Results The crazing resistance of alumina glass composite via Vita alpha ceramic expressed as the mean ΔT was 170 ℃. SEM micrograph indicate that Vita alpha ceramic fused to alumina glass composite, and no crack between the combination interface. Conclusion alumina glass composite can match to the Vita alpha ceramic fairly.
