Sic Heating Element For Lab

Description

SIC heating element (silicon carbide resistance heating element) is made of high purity green hexagonal silicon carbide as raw material, which is extruded and recrystallized at high temperature. Silicon carbide particles structure used in industrial and laboratory shows its special performance, under the condition of various applications especially in the oxidation and corrosive gas environment with the best service life without any support, silicon carbon rod element can be used in vertical or horizontal installation under the condition of 1600 ℃ and not deformation, provides great convenience for kiln design and use.

In the field of continuous operation, SIC heating element shows this characteristic especially. Its high load bearing characteristics are suitable for small volume and high power environment. Therefore, it is widely used in magnetic materials, powder metallurgy, ceramics, glass, analysis, non-ferrous metals and machinery and other industries of a variety of high temperature electric furnace and other electric heating equipment.

The main uses of Sic heating element in chemical experiments

1. For heating: Sic heating element for lab has excellent thermal conductivity and do not deform at high temperatures, thus they are widely used in heating equipment in chemical laboratories, such as hot plates and electric furnaces.

2. For oscillation: Silicon carbide rods have good bending strength and can withstand large vibration forces. Therefore, they are often used as oscillation rods in chemical analysis, such as stirring rods, etc.

3. For electrolysis: SIC heating element can be used as electrode materials. Due to their characteristics such as no deformation at high temperatures, corrosion resistance, and good electrical conductivity, they are widely applied in electrolysis experiments.

4. For the preparation of semiconductor materials: Silicon carbide rods have a uniform pore structure and thermal conductivity, and thus are widely used in the heat treatment processes of materials such as insulation and dense reaction materials during the preparation of semiconductor materials.

5. For other experimental equipment components: Sic heating element for lab can also be made into various shaped experimental equipment components, such as test tube racks and brackets. Due to their high-temperature resistance and corrosion resistance, they can meet the special requirements of experiments.

They can be replaced while the furnace is at operating temperature. The power to the  silicon carbide heating element being changed should be shut off, the spring clips and aluminum braid released, and the old SiC heater removed. The new  element should be inserted smoothly through the hot furnace with sufficient speed to ensure that the aluminum is not melted off the terminal end but not so fast as to cause thermal shock.

After being heated in the air, silicon carbide heating element forms a dense silicon oxide film on its surface, which becomes a protective film for soothing reaction and prolonging its life. In recent years, various coatings have been developed to prevent cracking of silicon carbide heater for use in furnaces with various gases.

The key factor for the best service of the SIC  heater is the correct choice of the surface load for the heating element according to the furnace design, environment and temperature. The value of the specific surface power determines the temperature field of the SiC electric heater over the entire cross section from its center to the surface. If exceeding the optimum specific surface power may lead to premature failure of SIC electric heaters, mainly due to cracking and burning out, and heating heater leads is also possible.
