Description

Silicon carbide heating elements are high-temperature ceramic components used in electric furnaces, they are featured by high electrical conductivity and resistance to extreme temperatures. Made of silicon and carbon, these elements are formed through a recrystallization process at temperatures exceeding 2150°C, lead to a long service life and high energy efficiency. They are the ideal choice for industries such as metallurgy, ceramics, and semiconductor manufacturing.

The silicon carbide heating element has the characteristics of high temperature resistance, oxidation resistance, corrosion resistance, fast heating, long life, small deformation at high temperature, easy installation and maintenance, and has good chemical stability.It has been widely used in electronics, magnetic materials, powder metallurgy, ceramics, glass, semiconductor, analysis and laboratory, scientific research and other high-temperature fields.

M Type Silicon Carbide Heating Elements start to being oxidized when heat to 800℃ in air, and a sio2 protect film will be generated in surface of hot zone when temperature get to 1000-1300℃,cristobalite will be crystallized at 1300℃,the protect film get to a certain thickness when the temperature get 1500℃ which make the oxidation speed being very slowly to stable. If continue to heat to over 1627℃, the protect film will be damaged and oxidation speed will be more rapid evidently and make the element damaged earlier.

Silicon carbide heating element manufacturers typically produce a family of elements using different grades of material and different manufacturing techniques to tailor each product to a specific range of application. The effects of furnace atmosphere on sic heater (Maximum Element Temperature) MET needs to be considered in designing the furnace. The lowest METs is achieved in vacuum, both because any protective silicon dioxide layer formed by pre-oxidation will deteriorate under hard vacuum and because SiC actually vaporizes at elevated temperature under high vacuum conditions.

Silicon carbide rod heater has metalized ends for electrical connections, and they often have both connections at one end, with two helical slots which stop short of the Other end, thus approximating a twisted hairpin form.

Due to its unique and excellent performance, M Type Silicon Carbide Heating Elements are widely used in various electric kiln with furnace temperature of 600-1500 °C for metallurgy, electronics industry, kiln industry, chemical industry, metal heat treatment, powder metallurgy sintering, ceramics, science. Used in fields such as experiments. Silicon carbon rods are also used as infrared light sources on instruments, making them ideal for high temperature heating elements.
