Customized rods made of alumina (Al2O3) ceramics, also known as resistance electric heating ceramic rods. Alumina ceramic rods are commonly used in electric heating elements, such as heating rods, where ceramic materials are widely used because they can withstand high temperatures. They can be used as supports or insulators for heating elements in electric heating devices to help distribute heat while preventing the current from directly contacting other parts of the heating equipment, ensuring safety and efficiency.
Alumina ceramic rods have the following characteristics:
High-temperature resistance
With a maximum operating temperature of up to 1650°C, it can be used in extreme thermal environments.
Excellent electrical insulation
With a breakdown strength of more than 10 KV/mm, it ensures safe use in high-voltage environments.
Customized size and shape
The length and diameter can be customized according to specific industrial needs to meet different application scenarios.
Good mechanical stability and wear resistance
The Vickers hardness is up to 15.7 GPa, ensuring durability and stability under physical loads.
Optimized thermal conductivity
The thermal conductivity reaches 27.5 W/(mK), effectively managing heat distribution and improving thermal efficiency.
Applications
Electric heating elements
Used as supports or insulators in heating equipment such as electric heating rods and electric heating tubes to help evenly disperse heat while preventing direct contact with current.
Electronic equipment
Used to dissipate heat and protect sensitive electronic components in power semiconductors, microprocessors, and LED lighting systems.
Industrial heating systems
As a component of industrial furnaces or heat treatment equipment, it provides structural support and thermal management.
Scientific research and laboratory applications
Used as laboratory heating elements in scientific research equipment, especially in experiments that require precise temperature control.
Alumina ceramic rods play an irreplaceable role in high-performance electric heating applications due to their excellent heat resistance, electrical insulation, and customization flexibility. The design of these ceramic rods fully considers the needs of industrial high-temperature environments, ensuring the safe operation and long-term stability of electronic equipment. Its uniform physical and mechanical properties, as well as its excellent thermal management capabilities, make it a preferred material in electric heating technology, especially for those applications that require extremely high performance and reliability.
