Silicon carbide heating element is a kind of high-temperature electric heating element. 

Raw materials and production: The silicon carbide heating element takes high-purity green hexagonal silicon carbide as the main raw material, and is manufactured through silicidation, recrystallization and sintering at a high temperature of 2200℃, and its shape is rod-shaped or tubular. 

Performance characteristics: Silicon carbide heating elements have the characteristics of high temperature resistance, oxidation resistance, fast temperature rise and long service life, as well as good chemical stability and high heating efficiency. Its resistance changes with the increase of temperature. It can work normally in an oxidizing atmosphere at 1450℃, and its continuous service life can reach 2000 hours. 

Application field: Silicon carbide heating elements are widely used in electronics, magnetic materials, powder metallurgy, ceramics, glass and other fields, serving as electric heating elements for various heating equipment such as tunnel kilns, roller kilns and vacuum furnaces. At the same time, it also plays an important role in industrial fields such as casting and steelmaking. 

Common types: Silicon carbide heating elements can be divided into various types such as stubby type, equal-diameter type, mountain-shaped type, U-shaped type, door-shaped type, and H-shaped type according to different shapes and applications, so as to meet the needs of different fields.
