Product Details
ED Type Silicon Carbide Rod
As an element that exhibits excellent performance in the field of
industrial heating, the ED-type silicon carbide rod is worthy of
in-depth analysis regarding its unique features.
In terms of material composition, silicon carbide, being the main
component, endows the silicon carbide rod with outstanding
high-temperature resistance. The equal-diameter structural design
ensures that the diameters of the heating part and the cold end
remain highly consistent, and this design feature holds significant
importance in practical applications. The heating part is formed by
pressing and sintering high-purity silicon carbide particles
through special processes. This process not only guarantees the
compactness of the structure but also constructs a good conductive
network inside.
In terms of the working principle, when an electric current passes
through the silicon carbide rod, its own resistance characteristics
become crucial. The existence of resistance enables electrical
energy to be efficiently converted into thermal energy, thus
realizing the heating function. When heated in the air, the surface
of the heating part of the element can reach a high temperature of
around 1400℃ - 1500℃. Under this high-temperature condition, a
dense silicon dioxide film will be formed on the surface of the
silicon carbide rod. The formation of this film is due to the
reaction between silicon carbide and the oxygen in the air at high
temperatures. However, its unique antioxidant effect can
effectively protect the internal silicon carbide structure of the
silicon carbide rod from further oxidation, thereby prolonging the
service life of the silicon carbide rod.
