用34ca30al2o3成功地制备了蓝宝石单晶板与氧化铝陶瓷管的连接。二氧化硅玻璃作为中间层。该玻璃对氧化铝陶瓷和蓝宝石单晶具有良好的粘附性能。在1550℃下加热10 min，从1200℃缓慢冷却至室温，得到无裂纹的接头。从热冲击试验来看，在225℃~ 0℃淬火后，一半试样出现裂纹，而在200℃~ 0℃淬火后，所有试样均未出现裂纹。由氧化铝管-蓝宝石板-氧化铝管组成的试样与由氧化铝管-氧化铝管组成的试样具有相当的抗弯强度。
The joining of a sapphire single crystal plate to alumina ceramic tube is fabricated successfully using 34CaO 30Al 2 O 3 .36SiO 2 glass as an interlayer. This glass showed good adhesion performance to alumina ceramics and sapphire single crystal. The joint with no crack was obtained by heating at 1550°C for 10 min and slow cooling from 1200°C to room temperature. From the thermal shock test, the half of the specimens showed the cracks after quenching from 225°C to 0°C, but all specimens showed no cracks after quenching from 200°C to 0°C. The specimen, composed of alumina tube-sapphire plate-alumina tube showed the comparable bending strength to the specimen composed of alumina tube-alumina tube.
