Electric Double Helix SiC Heating Elements For Electric Furnaces

Silicon Carbide (SiC) heating elements are non-metallic electric heating components manufactured from high-purity green hexagonal SiC crystals generated at temperatures exceeding 2200°C. These elements can operate at temperatures up to 1450°C and provide continuous service for over 2000 hours in vacuum atmospheres without requiring protective gas environments.

Physical Properties

Property	Value	Property	Value
Specific Gravity	2.6-2.8 g/cm³	Bend Strength	>300 kg
Hardness	>9 MOH'S	Tensile Strength	>150 kg/cm³
Porosity Rate	<30%	Radiancy	0.85

Usage Guidelines

Conduct resistance distribution testing before installation to ensure uniform furnace temperature and charge distribution across all elements
Handle with care during installation and maintenance as elements are brittle and susceptible to damage
When starting furnace operation, gradually increase voltage in stages - never apply full load immediately
