DB ( Dumbbell ) Type Silicon Carbide
What is a silicon carbide (SiC) heating element? It is a
non-metallic heating component that is widely used in
high-temperature applications. The main material is ultra pure
green hexagonal silicon carbide, which is processed at a high
temperature of 2400 °C to form billets and silicon crystals.
This heating element can operate in an oxidizing atmosphere at a
temperature of up to 1450 °C and has a continuous service life of
2000 hours. It offers excellent thermal conductivity and resistance
to high temperatures.
The evolution of heating element designs includes the development
of dumbbell shaped components with enlarged cold ends. These were
initially designed to reduce the cold end temperature by increasing
the cross-section and reducing resistance. However, with
advancements in technology, non dumbbell or ED type components have
emerged as more efficient alternatives.
These newer components use advanced technology to maintain terminal
cooling and have lower electrical resistivity. They offer improved
performance and are more space-efficient. Understanding the
properties and evolution of silicon carbide heating elements can
help users make informed decisions when choosing heating solutions
for their specific applications.
