Product Overview
ED-Type (Equal Diameter) Silicon Carbide Heating Elements are
high-performance non-metallic electric heating components designed
for extreme temperature environments. Crafted from high-purity
green silicon carbide and sintered at 2400°C, they offer
outstanding thermal stability and mechanical strength. Suitable for
continuous operation in temperatures ranging from 600°C to 1450°C, these elements are ideal for electric stoves, kilns, and
industrial heating systems across sectors such as glass manufacturing, chemical processing, and electronic materials
synthesis.
Key Features
High-temperature resistance up to 1450°C
Low thermal expansion for minimal deformation
Excellent chemical and oxidation resistance
Long service life with easy installation & maintenance
Custom diameters, lengths, and shapes available
