8.2.4 Soldering

Joints between ceramic and metal, and between one ceramic and another, based on material bonding can be created through soldering.
The ceramic is usually metallised prior to this process . The type of metallisation will vary according to whether hard or soft soldering is expected to follow, and must be appropriate for the particular ceramic material. Aluminium oxide and aluminium nitride are preferred ceramic materials for hard and soft soldering.
In addition to this, there are active soldering processes that dispense with metallisation of the ceramic and which require special active solders. Further soldering procedures are described in the literature .
