SiC Heating Rod

The silicon carbide heating rod, also known as the Silicon Carbide (SiC) rod, is an important non-metallic high-temperature electric heating element.

Main Raw Materials and Manufacturing Process

·         Raw Materials: The Silicon Carbide (SiC) rod is primarily made from high-purity green hexagonal silicon carbide (Silicon Carbide (SiC)).

·         Manufacturing Process: The raw materials are processed into blanks with a specific material ratio and then sintered at 2200°C through a recrystallization process to form rod-shaped or tubular elements.

Properties

1.      High-temperature Resistance: The Silicon Carbide (SiC) rod exhibits excellent high-temperature resistance, with a normal operating temperature of up to 1450°C and continuous operation for thousands of hours.

2.      Oxidation and Corrosion Resistance: The Silicon Carbide (SiC) rod has good oxidation and corrosion resistance.

3.      Quick Heating and Long Life: The Silicon Carbide (SiC) rod heats up rapidly and has a long service life.

4.      Small Deformation at High Temperatures: The Silicon Carbide (SiC) rod exhibits minimal deformation at high temperatures, maintaining good stability.

5.      Easy Installation and Maintenance: The Silicon Carbide (SiC) rod is relatively easy to install and maintain.

Application Fields

Silicon Carbide (SiC) heating rods are widely used in various high-temperature applications, including but not limited to:

·         Electronics

·         Magnetic materials

·         Powder metallurgy

·         Ceramics

·         Glass

·         Semiconductors

·         Analytical chemistry

·         Scientific research

Silicon Carbide (SiC) heating rods are used as electric heating elements in various heating equipment such as tunnel kilns, roller kilns, glass furnaces, vacuum furnaces, muffle furnaces, smelting furnaces, and more.

Working Principle

The working principle of the Silicon Carbide (SiC) heating rod is primarily the conversion of electrical energy into thermal energy through the电热效应 (electrothermal effect). When an electric current passes through the Silicon Carbide (SiC) rod, due to its resistance, the current releases a significant amount of heat, heating up the rod and ultimately achieving the purpose of heating the object.

Precautions

·         The Silicon Carbide (SiC) rod is hard and brittle, so it requires careful handling during transportation and installation to avoid severe shocks and impacts.

·         During installation, it is necessary to ensure that the distance between the Silicon Carbide (SiC) rod and the heated object or furnace wall is greater than or equal to 3 times the diameter of the heating section, and the center-to-center distance between Silicon Carbide (SiC) rods should be no less than 4 times the diameter of their heating sections.
