Inquiry NowProduct Description
General Description:
Material: Silicon carbide (SiC) tubes and rods are ceramic products made from silicon carbide, a compound consisting of silicon and carbon.
SiC is known for its exceptional mechanical strength, high thermal conductivity, excellent thermal shock resistance, and resistance to wear, corrosion, and extreme temperatures. SiC tubes and rods find applications in industries such as aerospace, automotive, chemical, and semiconductor manufacturing.
It can be produced in different forms, such as reaction-bonded silicon carbide (RB-SiC), sintered silicon carbide (SSiC), or recrystallized silicon carbide (RSiC). These forms have varying manufacturing processes and properties.
Manufacturing Process: The manufacturing process for silicon carbide tubes and rods can vary depending on the specific form:
- Reaction-bonded silicon carbide (RB-SiC): This process involves infiltrating molten silicon into a porous carbon preform, which reacts with carbon to form silicon carbide in situ.
Operating temperature range: Typically up to approximately 1600-1700°C (2912-3092°F)
Maximum temperature for short-term use: Around 1800-1900°C (3272-3452°F)
RbSiC exhibits good thermal stability and can withstand rapid temperature changes, making it suitable for high-temperature applications.
- Sintered silicon carbide (SSiC): SSiC is produced by sintering a mixture of silicon carbide powder and a small amount of sintering aids at high temperatures.
Operating temperature range: Typically up to approximately 1600-1800°C (2912-3272°F)
Maximum temperature for short-term use: Around 1800-1900°C (3272-3452°F)
SSiC exhibits exceptional mechanical strength and can withstand high temperatures while maintaining its structural integrity.
- Recrystallized silicon carbide (RSiC): RSiC is made by heating a mixture of silicon carbide and carbon at high temperatures, causing the silicon carbide to recrystallize and form a dense, interconnected structure.
Operating temperature range: Typically up to approximately 1500-1600°C (2732-2912°F)
Maximum temperature for short-term use: Around 1650-1700°C (3002-3092°F)
RSiC demonstrates excellent thermal shock resistance and retains its mechanical properties at high temperatures
