本文介绍了羟基催化键合所产生的键的机械损失的调查。这种损失的大小的评估是重要的，以确定热噪声水平的引力波探测器的粘结悬浮液。三个样品进行了研究，不同的几何形状和表面积的债券。在两种情况下，键合在两片熔融石英之间，而在第三种情况下，熔融石英片附接到蓝宝石衬底。在每种情况下，使用硅酸钠溶液作为粘合剂。评价粘结材料的厚度和杨氏模量，使得能够获得粘结材料的固有机械损耗因子的值。
This paper describes investigations into the mechanical losses of bonds created by hydroxy-catalysis bonding. Evaluation of the magnitude of such losses is important for determining thermal noise levels in bonded suspensions for gravitational wave detectors. Three samples were investigated with bonds of varying geometries and surface areas. In two cases, the bonds were between two pieces of fused silica, whilst in the third a fused silica piece was attached to a sapphire substrate. In each case sodium silicate solution was used as the bonding agent. The thickness and Young's modulus of the bond material were evaluated enabling values for the intrinsic mechanical loss factor of the bonding material to be obtained.
