Aluminum Nitride Powder |
It is stated that
Kyma
AlN has
10-15
times greater Thermal
Conductivity, 50-75%
greater bending
strength, and a
coefficient of Thermal
Expansion more closely
matching that of
silicon. A light tan/
white to gray powder
which can be fired to
translucence
Aluminum Nitride Typical
Chemical Properties
Available:
a) Typical
chemistry: N= 33.6% min., Al= 65.4% min. Purities are
available from 99% (industrial grade) to 99.8% (high
purity grade).
b) Three
different basic AlN chemistries are available
Aluminum
Nitride Typical Physical Properties Available:
a) Single
crystals, sintered pieces, rods, targets, pellets,
whiskers, grinding media, coarse grains for fillers, and
fine powder
b) Granules and powder are available from as coarse as
60 mesh (250 microns) and finer down to a 0.5 micron
product. The finest commercial grade available in
tonnage lots has an average agglomerated particle size
of approximately 1.8 microns.
