ED Type Silicon Carbide Rod
Product information:
One reason for the aging of silicon carbide rods is the increase in
resistance after normal use, and another reason is that the
lifespan of silicon carbide rods ends prematurely due to incorrect
operating procedures during use. The reason for abnormal aging of
silicon carbide rods is that the voltage was applied too quickly
during initial use, resulting in uneven heating and causing the
rods to not adapt to the temperature inside the furnace, leading to
rapid wear and tear and affecting their service life. Secondly, the
silicon carbide rod was not installed correctly during use. When
the temperature inside the furnace rapidly heats up, the silicon
carbide rod also expands slightly. However, there is no gap left
for the components during installation, which affects the surface
expansion of the silicon carbide rod and shortens its service life.
Of course, another reason is that the silicon carbide rod was not
properly matched during use, which can quickly shorten its service
life. The latter reason is also a common occurrence, which is that
under high temperature conditions, the O2, CO2, and water vapor in
the air can strongly promote the oxidation of carbon nanotubes,
generating a glassy SiO2 film. The resistivity of SiO2 is higher
than that of SiC, which increases the resistance. Because of this
layer of SiO2, the thin film can protect the inner layer of Sic
from further oxidation, so after continuous use for a certain
period of time, the increase in resistance will slow down.
