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 .
