Formula: |
(Ca¡¤Sr¡¤Ba)CO3:
ZrO2 |
Purpose: |
The material is an electronic
emitting material for producing heated cathode in fluorescent
lamps.It is a
cathode
crucial
material for
low-pressure
discharge
lamps
and
light
manufacturing.
It is
formulated
into
the
slurry
and
coating
on the
based metal
by
electrophoresis
and
dipping
method.
Through
decomposed
by heating,
the emitting
cathode
electron
rely
surplus
barium
collided
with
positrons
of mercury
vapor in the
lamp tube
produces
253.7nm
UV
that
excite
the
phosphor
in the tube
to give
off visible
light.
The
end-of-life
of lamp
depends
on
the
quality
of
the
electronic
powder if
exclusion of
other
factors. It
is
called
¡°heart
material¡±
in light
industry. |
