It’s used as ceramic armour to provide superior ballistic performance for composite armor protection systems and it finds uses in aerospace and automotive components, nuclear energy plants and thin film semiconductors.
Silicon carbide tube is an incredibly hard, lightweight and durable material commonly used in industrial applications like refractory furnaces, shell-and-tube heat exchangers and high temperature thermal couple protectors. This makes it a perfect choice for these tasks due to its universal corrosion resistance, high thermal conductivity and extreme hardness.
Sintered Silicon Carbide tubes are used in a range of applications such as chemical process equipment, power generation and papermaking. As an economical and lightweight alternative to steel, the material offers excellent wear- and corrosion resistance.
Silicon carbide stands apart from other ceramics due to its exceptional dimensional stability and resistance to temperatures up to 1400 degrees Celsius. Furthermore, its Young’s modulus exceeds 400 GPa, giving it unbeatable strength and durability.
It is an economical and lightweight alternative to stainless steel that can easily be machined. Its high temperature resistance and hardness make it suitable for use in harsh environments such as chemical and petrochemical industries.
Material is offered in various sizes and thicknesses that can be custom formed to your requirements. It’s capable of being formed into rings, plates, bars and rods for many different applications.
Its strength and corrosion resistance make it the ideal choice for chemical processing, refining and mining applications as well as pulp and paper mills. Furthermore, its shock resistance and low sliding friction make it suitable for pumping applications as well.
Sentro Tech stocks and sells a comprehensive selection of top-tier RSiC and SSiC tube in both standard lengths (up to 72 inches/1828mm) as well as custom lengths.
SSiC is a higher purity material with increased hardness, better mechanical properties and greater corrosion resistance. As such, it has become the go-to material for applications where high purity is essential.
High Corrosion Resistance
Silicon carbide tube is superior to other metal materials when exposed to liquid and gaseous chemicals, such as hydrochloric acid, sulfuric acid and nitric acid; bases like amines or potash; solvents like acetone or benzene.
The corrosion resistance of silicon carbide is primarily determined by its pore size and distribution throughout the surface. Pore size affects corrosion resistance much in the same way steel’s porosity does, similarly.
However, it is uncertain whether pore size is the only factor responsible for corrosion behavior. A pore size of approximately 5 m has been shown to have minimal effect on SiC’s corrosion resistance when exposed to nitric acid. Therefore, SiC that comes into contact with highly acidic or corrosive solutions must be treated differently than when exposed to slightly acidic or neutral solutions.
Recently, it has been reported that adding boron and carbon to solid state sintered and chemically vapour-deposited SiC can improve its oxidation resistance. The behavior of SiC containing boron and carbon depends on its crystal orientation as well as any additives added during sintering. These additives can be used to modify the eutectic point or form protective oxide scales on top of the material for improved protection against oxygen attack.
To test the oxidation resistance of C/C-SiC after exposure in molten chloride salt, samples were subjected to mechanical testing and analysis with scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX) scans. EDX imaging of surface A (front surface) before and after exposure revealed that oxidizing impurities present in the molten chloride salt react with residual elemental silicon on the sample surface, forming an even thick layer of SiO2 across its whole surface area.
This is a positive indication that, despite the large amount of free Si on the surface, no deep corrosion has taken place. Furthermore, this oxidation reaction does not appear to have affected the strength of C/C-SiC matrix in any way; suggesting that molten chloride salt cannot react with carbon fiber and SiC components in this composite.
High Thermal Conductivity
Silicon carbide tube is a type of ceramic pipe with excellent thermal conductivity. It finds applications in industries and processes such as fuel gas furnaces and tunnel kilns.
It is ideal for various heat treatment processes in steel, metallurgy and chemical industry due to its high hardness, excellent thermal shock resistance and corrosion resistance.
SiC is an ideal material for desulphurization nozzles due to its superior wear resistance and corrosion resistance. Furthermore, it retains its geometry during blasting operations at approximately one fifth the weight of tungsten carbide.
This makes it the ideal material for use in industrial applications such as pumps, bearings and extrusion dies. It is resistant to extreme temperatures, acids and corrosive liquids.
Sintered silicon carbide nozzles are widely used in the power and coal industries, replacing tungsten carbide components due to their superior wear and corrosion resistance. This ensures that nozzles remain in safe working condition throughout their entire service life.
The use of this material helps reduce costs in the manufacturing process since it’s lighter than other materials. This can save money on maintenance and replacements over time.
Additionally, it can be produced in various shapes and sizes. Due to its lightweight nature, low mass, and high elastic modulus, it has become a popular choice for vacuum tubes and wafer carriers.
It is an ideal material for semiconductor and coating industries due to its high thermal conductivity, low coefficient of expansion, and resistance to oxidation. This makes for low maintenance requirements as well as reduced component recycling.
Other advantages of silicon carbide include its wide band gap, high flexural strength and electrical resistivity. These characteristics make it suitable for many other applications like microelectronics, optics and medical technology.
It is an ideal material for machining, as its higher Young’s modulus than most other ceramics provides a stable and solid surface for the workpiece – increasing productivity and decreasing downtime.
Silicon carbide is one of the lightest, strongest and hardest ceramic materials ever developed. Not only that, but it’s highly resistant to abrasion as well as having excellent chemical resistance.
Semiconducting fine ceramics have many industrial uses, and are commonly found in high-temperature environments as refractory material. But its versatility also extends to other industrial markets.
Due to its unique properties, aluminum is an ideal alternative to traditional metals for applications requiring high temperature strength, excellent corrosion resistance and low weight. Other advantages of this alloy include its superior thermal conductivity, resistance to acid and exceptional resistance to mechanical shock.
Sintered silicone carbide seal faces are becoming more and more popular in automotive water pumps due to their superior performance compared to aluminium oxide seal faces. Furthermore, these seal faces boast greater thermal shock and wear resistance, which allows them to last longer in U.S. and European cars than conventional seal faces do.
One area where silicon carbide is being utilized to save weight is in power device manufacturing. These can be much smaller and lighter than comparable-rated silicon power devices, which is especially crucial in large power management and distribution circuits found on modern aircraft and spacecraft.
Silicon carbide can also be utilized to manufacture high-temperature gas sensors. These are effective in detecting hydrogen, carbon monoxide, and other volatile substances within deep oil wells, natural gas fields, and geothermal energy production wells.
These gas sensors can enhance drilling operations’ safety by sending out early alerts when hazardous gases are present. Furthermore, they track the efficiency of a drilling process, which in turn increases efficiency and lowers costs.
In addition to gas sensors, silicon carbide tube has other applications due to its lightweight characteristics. In the aerospace industry, it has been employed as a replacement for liquid cooling systems on F-22 fighter jets due to its superior abrasion and temperature resistance; additionally, it’s being utilized in space telescope mirrors.
