advantage of reaction bonded silicon carbide tubes

Reaction bonded silicon carbide (RBSC) is one of the most advanced ceramic materials. also silicon carbide tubes possess impressive strengths in terms of strength, corrosion resistance and thermal shock resistance. Assemblage can be achieved by infiltrating parts made up of SiC and carbon with liquid silicon, and reacting them with carbon particles to form more SiC that bonds to initial particles.


Reaction Bonded silicon carbide tubes are excellent material to choose for high-performance applications due to its superior strength and durability, along with several key advantages that enhance efficiency and performance, such as superior thermal conductivity.

RB SiC can be used for making various components and assemblies, including mechanical seals, kiln furniture and semiconductor manufacturing equipment due to its excellent corrosion resistance, wear resistance, impact resistance and chemical resistance properties. Furthermore, its shapeability enables engineers to form custom engineered pieces suited for processing raw materials into equipment with ease.

Refractory silicon carbide can be manufactured through two main processes, reaction sintering and pressureless sintering, both of which greatly impact its final microstructure. Reaction-bonded silicon carbide can be created by infiltrating compacts of coarse and medium grained SiC particles with liquid silicon; the resultant material binds these initial particles and forms an extremely tough ceramic capable of withstanding high working temperatures, resistant to oxidation, and resistant to acid corrosion.

Oxide bonded silicon carbide (OBSC) is an affordable material that can still withstand high temperatures, making it suitable for load bearing furniture such as kiln furniture. Due to its thermal shock resistance and shape-forming capabilities using the Blasch process, OBSC is often chosen.


Reaction bonded silicon carbide (RBSC) offers outstanding strength and durability, and can be formed into complex shapes such as tubes and bellows to meet specific design requirements in demanding environments. Due to its excellent abrasion- and impact resistance, reaction bonded silicon carbide is an ideal material choice for high-value industries like energy production, metallurgy production and automotive production – plus corrosion damage resistance as well as temperature shock tolerance!

This material boasts superior bending strength compared to standard nitride-bonded silicon carbide, making it easy to form intricate designs with this material. Furthermore, its wear and corrosion resistance make it suitable for industrial heat-treating furnaces.

High thermal conductivity facilitates improved efficiency while its dimensional stability guarantees consistent use and changing temperatures. Its low coefficient of thermal expansion also helps prevent damage caused by sudden shifts in operating conditions.

reaction bonded silicon carbide tubes are exceptional choice for use in iron and steel industries, helping reduce maintenance costs by prolonging equipment lifespan and service life. Made of superior ceramics that feature excellent resistance against corrosion and high temperatures as well as impressive bending/failure strength properties; additionally it can withstand heavy-duty sintering operations without showing signs of damage – qualities which significantly lower maintenance costs while increasing production throughput.

Thermal Conductivity

Reaction Bonded Silicon Carbide Tube (RBSC) is an exceptional ceramic material with superior strength and thermal conductivity, as well as resistance to high temperatures and chemical corrosion – ideal for power generation, metallurgy, semiconductor manufacturing and wear resistance applications. Furthermore, its low coefficient of thermal expansion makes RBSC ideal for use as kiln furniture and mechanical seals.

RBSC ceramics boast high thermal conductivity due to their unique microstructure. Fabricated by infiltrating compacts of mixtures of SiC and carbon with liquid silicon, which reacts with the carbon, producing more SiC and bonding existing SiC particles together – an energy-saving approach over traditional sintering.

Reaction-bonded SiC is available both pre-turned and forged shapes to meet a range of applications. Due to its excellent sintering properties and as-fired dimensional accuracy, reaction bonded SiC makes for cost-effective manufacturing of large sized complex shape structural products compared to traditional sintered ceramics.

Corrosion Resistance

Reaction bonded silicon carbide (RB SiC) is an exceptionally tough, strong, and durable material with an outstanding resistance to fracture and deformation. With a low coefficient of thermal expansion it can withstand high temperatures without deforming, cracking, or breaking; additionally silicon carbide tubes offer excellent wear resistance as well as being highly resistant to acids (hydrochloric, sulfuric and hydrobromic acids) and alkalis (e.g. hydrobromic acids).

Silicon carbide is an increasingly popular ceramic material for applications requiring corrosion resistance, abrasive wear resistance and thermal conductivity. Common applications for silicon carbide include shot blast nozzles and cyclone components; its reaction-bonded variant has superior strength to allow forming into various shapes or sizes – while its low coefficient of thermal expansion makes it suitable for piping systems.

Reaction bonded silicon carbide is an ideal choice for harsh environments due to its chemical stability and temperature tolerance, being less prone to corrosion than oxide-bonded products and having greater temperature tolerance than nitride-bonded varieties. As a result, reaction bonded silicon carbide has become the go-to material in lithium battery manufacturing and semiconductor production applications requiring materials that can withstand high temperatures in challenging conditions.
