Silicon Carbide (SiC) to Metal Joining

As the cost of producing SiC ceramic and as the technology to “cast” complex parts with SiSiC composite ceramics matures, there is increasing applications for bonding SiC based ceramics to metals. Applications are expanding in electronics (LED’s and semiconductors), optical mirrors, energy production and aerospace.           The challenge in many of […]

Sapphire to Metal Hermetic Seals

We get many calls about hermetically sealing sapphire (single crystal aluminum oxide) to metal flanges and this post addresses some of the applicable commercial methods used.  Sapphire to metal seals many times are used in sensor housing like those seen in Figure 1. In this application these titanium housing are actively soldered (S-Bond) to the […]
