Advanced Durability With Reaction Bonded SiC
Reaction Bonded SiC (RBSC) is an extremely durable material used in multiple applications due to its superior wear resistance and thermal stability. Read more about it here!
Reaction bonded production begins by mixing together materials composed of SiC and carbon. Once formed, this green body undergoes green machining for precision and surface finish.
Wear Resistance
Silicon carbide stands out as one of the top performers when it comes to wear resistance, thanks to a reliable manufacturing process that results in tough, durable wear-resistant linings that have proven their worth in demanding industrial environments.
Reactive Bonded Stainless Steel Composite (RBSC), created through an innovative reaction bonding process in which molten silicon is infiltrated into a porous carbon preform, allows RBSC to maintain its shape at high temperatures while still being structurally sound and resistant to acids corrosion. Inoltre, its thermal expansion rate is extremely low and corrosion resistance has also been proven.
SiC is widely known for its hardness, resistance to wear, heat and chemical erosion as a material used for mechanical seals and high-performance pump components. Depending on its grade, SiC also boasts excellent flexural strength at elevated use temperatures as well as good tensile strength – qualities which make it suitable for applications where vibration and shock may occur.
Thermal Resistance
RBSC’s high thermal resistance makes it a leader in demanding industrial applications, dissipating heat efficiently to allow its use in hot environments without additional downtime and maintenance requirements.
Reaction bonded silicon carbide (RBSC) is produced by infiltrating compacts composed of mixtures of SiC and carbon with liquid silicon, whereby its reactions with the carbon result in further silicon being formed that bonds initial SiC particles together – unlike sintered SiC which is produced through conventional ceramic forming processes using non-oxide sintering aids.
Song’s research suggests that composite precursor impregnation increases SiC content by controlling the reaction between liquid silicon and amorphous carbon, eliminating pore-clogging phenomena, and producing dense RB-SiC with high modulus and strength – producing dense RBSC with an exceptional combination of structural strength, chemical resistance, temperature tolerance and wear resistance – making RBSC the material of tomorrow. Inoltre, this refractory material boasts incredible durability in high wear areas along with superior erosion resistance and thermal shock stability – making RBSC the material of tomorrow.
Resistenza chimica
Reaction Bonded SiC is an extremely tough and resilient ceramic material, known for being chemically inert and resistant to oxidation and corrosion. Able to withstand high temperatures while still remaining strong, Reaction Bonded SiC makes for ideal components in industrial settings like pumps, nozzles, cuscinetti, flow control chokes and the like.
Manufacturing of RB SiC involves injecting liquid silicon into porous carbon material packed into its final shape using reactive melt infiltration (RMI). This process ensures minimal residual carbon clogs pores, and allows molten silicon to react with carbon to form silicon carbide [1, 2].
Reaction-bonded silicon carbide offers exceptional thermal conductivity, low coefficient of expansion, and resistance to thermal shock, oxidation and corrosion; making it an excellent choice for semiconductor processing equipment such as kiln shelves and furniture or crucibles. Inoltre, its lightweight properties and strength make it useful in military or aerospace equipment such as armor plates or rocket nozzles.
Thermal Shock Resistance
Thermal shock resistance of materials can be measured by their ability to endure stress under rapid temperature changes, depending on their structure, properties and environment. Such stress can result in cracks, deformations or fractures within their structures, properties or environments – giving rise to potential cracking issues for example.
Reaction Bonded Silicon Carbide features an intricate lattice structure of bonds between carbon and silicon atoms that provide it with significant mechanical strength, high thermal conductivity and low density – qualities which contribute to its outstanding thermal shock resistance.
Thermal shock resistance of materials depends on a number of factors, including initial crack initiation rate and propagation speed, length of crack and its inception conditions. RBSC material has the capacity to sustain high amounts of crack stress while resisting various damage mechanisms – from matrix cracks forming within pores between fiber bundles to radial cracks along pore walls – without suffering significant degradation or crack formation.
