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.
