Stepanov's Method Grown Sapphire Wafer 2Inch 3inch 4inch 6inch R-Axis M-plane
Stepanov's
method
is
used
for
growth
of
monocrystal
sapphire
details
of
various
configurations,
including
sapphire
rods,
pipes
and
tapes.
The
method
of
Horizontally
Directed
Crystallization
is
widely
used
in
the
synthesis
of
large
sapphire
monocrystals.
The
elements
of
the
directed
crystallization
and
zonal
melting
are
successfully
combined
in
the
Gorizontally
Directed
Crystallization
(HDC)
method.
The
crystal
grows
at
slow
movement
of
the
local
melted
zone
along
the
container
with
the
furnace
charge,
having
a
boat
form.
The
Horizontal
Directed
Crystallization
method
provides
receiving
of
monocrystalline
sapphire
with
small
sizes
dispersion
of
cross
section
and
allows
to
grow
up
sapphire
monocrystal
of
any
crystallographic
orientation
in
the
form
of
plates
of
the
record
sizes
unattainable
at
use
of
other
growth
methods.
