Reaction Bonded Silicon Carbide Tube
Reaction Bonded Silicon Carbide (RBSiC) is an ideal material choice for applications requiring high strength, temperature stability and corrosion resistance, such as furniture making kilns, mechanical seals and semiconductor manufacturing equipment. RBSIC boasts excellent thermal conductivity and oxidation resistance, and can be manufactured into large sizes and complex shapes with excellent as-fired dimensional accuracy.
Excellent thermal conductivity
Reaction bonded silicon carbide is lightweight and features excellent thermal conductivity. It is acid-resistant and comes in various shapes such as nozzles and cyclone components for use. Due to its strength and wear resistance properties, reaction bonded silicon carbide makes an excellent material choice for equipment that experiences continual wear.
Reaction-bonded silicon carbide is produced by injecting liquid silicon into porous carbon or graphite preforms, where it interacts with carbon to form more silicon and densify the material more densely. This process may be accomplished through different methods such as reaction sintering, hot-press sintering or liquid phase sintering; additionally infiltration may be further increased with carbon or boron carbide additives to enhance silanization.
RBSiC is an ideal material choice for ceramic applications requiring high temperatures and stable dimensions, such as spray nozzles or wear-resistant cyclones, that demand high heat resistance and good dimensional stability. Available in numerous shapes, sizes and tolerances RBSiC fits a variety of industrial uses with its wear resistance qualities being particularly suited to spray nozzles or wear resistant cyclones.
High wear resistance
Reaction bonded silicon carbide ceramic tubes boast excellent wear resistance. Able to withstand both high temperatures and corrosion, they make ideal material choices for many applications including iron and steel annealing lines as well as powder metallurgy applications requiring high impact resistance and strong abrasive resistance, Duratec’s reaction bonded sic tubes can be made into various shapes and sizes to meet customer specifications as well as being used in heat treatment furnaces, nozzles and high performance chemical pumps – ideal applications of reaction bonded sic tubes!
Reaction bonded sic is the ideal material choice for applications requiring wear resistance at an economical cost. As one of the hardest materials available, it can withstand high temperatures without degrading; high-pressure shocks and vibrations don’t affect it either! Having similar hardness and strength as steel but half its weight; its thermal conductivity exceeds even that of copper! Reaction bonded sic also has anti-corrosive properties while providing double acid corrosion resistance compared to copper!
Reaction sintered silicon carbide is an ideal material for many industrial applications, including spray nozzles and shot blast nozzles. Additionally, this durable material can be found in power plants to control pollution levels and protect components against erosion; in addition, its resistance to corrosion and abrasion makes it suitable for desulfurization and denitrification systems as well as mining-industry cyclone components.
Corrosion resistance
Reaction-bonded silicon carbide, created by infiltrating liquid silicon into porous carbon or graphite material that has been formed into your product’s shape, offers greater corrosion resistance than its direct sintered counterpart. Furthermore, large sizes with superior as-fired dimensions accuracy allow this form of SiC to produce complex shapes from one material source.
RB-SiC stands out for its exceptional strength, thermal stability and chemical resistance; making it suitable for high temperature environments like tunnel kilns and mechanical seals. Furthermore, this lightweight material makes RB-SiC an excellent choice when subject to high loads.
RB-SiC corrosion resistance depends on an oxide barrier which inhibits direct reaction between silicon carbide and an attacking species like oxygen or nitrogen, and silicon carbide. Furthermore, silica acts as a replacement material during reaction processes thanks to diffusion of oxygen through its oxide layer barrier.
RBSiC stands out among materials thanks to its high melting point and low coefficient of thermal expansion, along with its hardness and resistance against abrasion and impact. Furthermore, its inertness means it can be used with chemical processing equipment while its ability to withstand high temperatures and corrosion make it particularly suitable for temperature sensing tubes applications.
Excellent dimensional stability
Silicon carbide ceramics offer superior wear resistance in various demanding environments. From precision parts in lithium batteries and semiconductor manufacturing to large wear components such as spray nozzles and mining cyclones. Their high dimensional stability also enables custom and unique product designs.
Reaction bonded silicon carbide is manufactured by mixing powdered SiC and carbon with an organic plasticizer before molding and firing it into desired shapes. Once fired, this reaction ceramic contains more SiC and carbon than in its initial mixture, creating highly durable results at a much more cost-effective process than sintered silicon carbide – suitable for applications where lower hardness but increased thermal stability are desired.
No matter the size or shape of your product, it is crucial to consider dimensional stability of the ceramic material you select. From precision parts for cutting-edge technology to long-wearing wear components for harsh industrial environments, your aim should be for your parts to maintain their correct shapes throughout curing and debinding processes – this makes reaction bonded or pressureless sintered silicon carbide ceramics an excellent option.
