Silicon carbide is a lightweight ceramic material characterized by high mechanical strength, good wear resistance and resistance to chemical corrosion.
Sintered and reaction-bonded silicon carbide have numerous industrial applications, from blast nozzle replacements that reduce compressor requirements and downtime for replacement, to structural supports in marine construction projects.
Excellent Corrosion Resistance
Sintered silicon carbide’s exceptional corrosion resistance makes it a favorite material choice in industries like metallurgy and power generation, where chemical wear-resistance is key. Furthermore, this material boasts low thermal expansion while offering excellent resistance against acid corrosion.
Reaction-bonded silicon carbide (RBSiC or SiSiC) is a refractory ceramic material created from liquid silica mixed with penetrating compacts of carbon and silicon and fused at extremely high temperatures, giving rise to hard Mohs 9.3 material that is an exceptional thermal shock and corrosion-resistant refractory ceramic material.
Material used for furnace lining applications includes copper melting furnace liners, zinc melt tank liners and aluminum smelter retort retorts and crucibles; as well as being utilized as thermocouple protection tube ceramic material and protective ceramic tube material. Furthermore, mechanical seals and pump components may also benefit from using this material that has a service life that exceeds that of alumina by five to seven times.
Excellent Wear Resistance
Equipment performance in high wear environments depends heavily on the materials chosen to protect it. Hardness, abrasion resistance and corrosion resistance are among the key properties necessary for success; silicon carbide ceramics stand out as being ideal because they have three times harder surface hardness than alumina (corundum) ceramics – second only to diamond and cubic boron nitride – plus very strong properties along with low thermal expansion rates.
Sintered silicon carbide has long been used in production systems to line cyclones, chutes, hoppers, tubes and pipes, wear resistant parts such as bearings and mechanical seals and as a corrosion inhibitor in acid environments. Reaction Bonded Silicon Carbide (RBSiC) offers low cost material options when wear resistance of SiC ceramics are not needed; or where intricate shapes cannot be manufactured using more costly sintered materials. RBSiC also boasts excellent anti-oxidation characteristics with outstanding toughness; making it an excellent anti-corrosion treatment option when exposed to acid environments. React Bonded silicon Carbide provides excellent corrosion resistance as well. Reaction Bonded silicon Carbide offers excellent corrosion resistance as well as corrosion resistance against acid environments compared with its SiC counterpart; its wear resistance makes RBSiC an excellent low cost material alternative when worn directly versus SiC ceramic ceramic materials cannot make up complex shapes required of sintered materials; while React Bonded silicon Carbide offers good wear resistance, anti-corrosion characteristics as well. Reacted Bonded silicon Carbide offers similar wear resistance as well. Reacted Bonded Silicon Carbide provides anti corrosion resistance against acid environments. Reacted Bonded Silicon Carbide offers wear resistance in acid environments while the latter also features very good wear resistance, anti corrosion and anti oxidation characteristics and offers corrosion resistance in acid environments while both types of material options offer wear resistance; while Reacted Bonded silicon Carbide offers low cost material option offering good anti oxidation characteristics and anti-oxidation capabilities due to corrosion resistant antioxidation resistance is corrosion protection from its more costly sintered counterpart RBSiC provides good oxidation is low cost alternative which used oxidization properties as it stands itself out-oxidization properties which offers excellent corrosion resistant components offered oxidization qualities not required wear resistance to acid environments while corrosion resistant features that sintered material has good anti abrasion resistance but with anti-oxidation properties unlike sintered materials unlike ceramic alternatives and anti-oxidation properties over-oxidation characteristics unlike that both wear resistance over acid environments; it too anti-oxidization characteristics too difficult.

Excellent Thermal Expansion
Silicon Carbide is a ceramic material capable of being transformed into hard, dense abrasives by means of sintering. Found naturally as moissanite mineral, but mass produced synthetically since 1893 for use as an abrasive. Due to its ability to withstand high-temperature environments and chemical corrosion resistance, silicon Carbide makes an ideal material choice for industrial furnace operations where equipment efficiency and lifespan rely heavily on material choices.
Sintered silicon carbide excels at withstanding erosion, abrasion and frictional wear as well as corrosion – making it the perfect material choice for applications including chemical manufacturing and energy technology, paper production and pipe systems.
Sintered silicon carbide’s strength, creep deformation resistance, low coefficient of thermal expansion and resistance to acid corrosion make it an attractive ceramic material for armor protection applications. Furthermore, its exceptional ballistic performance in composite armor protection systems and superior ballistic performance compared to steel-based systems make sintered silicon carbide an excellent chemical inertness solution in hostile chemical environments.
Excellent Mechanical Strength
Sintered silicon carbide stands out as an ideal material for ballistic protection thanks to its superior strength, hardness, and low specific density properties. It can withstand significant amounts of bullet energy without shattering, making it a viable alternative to currently available engineered ballistic ceramics such as aluminum oxide and zirconium dioxide.
Silicone carbide can be utilized in industrial production processes like sintering and reaction bonding to produce various structural components, including beams, rollers, cooling air pipes, temperature measuring pipes and burner nozzles. Silicon carbide can also be formed into abrasion- and corrosion-resistant seals for use in pumping systems. Other advantages of silicon carbide include its resistance to acid, oxidation and compounds as well as its excellent wear resistance, high shock resistance and small creep deformation properties. These are among the many reasons why it has become one of the most important industrial ceramics today, playing an essential role in semiconductor wafer handling equipment and rigid, dimensionally stable structures such as vacuum chucks and chemical mechanical polishing blocks.
