Enhance Performance With Nitride Bonded Silicon Carbide
Silicon carbide is an invaluable material, offering unparalleled corrosion and wear resistance, superior thermal stability and unparalleled thermal conductivity. Silicon carbide’s versatility has paved the way for numerous industrial uses across a variety of sectors.
Material known for its outstanding impact strength and high load-carrying capacity, making it suitable for use in both shaped refractories and process industry applications.
High Temperature Strength
NBSIC stands out in demanding industrial environments due to its excellent temperature resistance. It boasts superior load-carrying capacities at elevated temperatures when compared with other oxide-bonded silicon carbide products and also provides good chemical resistance against acids, molten salts and halogens.
Cast NBSIC into complex geometric forms using the Blasch process, making it possible to adapt this material precisely to an existing metal part’s dimensions without needing additional finishing processes such as grinding.
NBSIC can be formed into various shapes and sizes to meet a range of applications, from side walls of aluminium melting pots, lower stacks in blast furnaces, kiln furniture and much more. With its superior mechanical strength and dimensional stability, NBSIC is capable of withstanding extreme service conditions with reduced downtime resulting in greater uptime – soil abrasion tests showed significant less intensive wear from NBSIC than that found with boron-containing steels in both light and heavy soil conditions.
Extreme Hardness
Nitride-bonded silicon carbide boasts exceptional hardness comparable to that of diamond and outshone steel in wear resistance. Furthermore, it boasts superior load-carrying capacities as well as being capable of withstanding extreme temperatures without suffering structural weakness, resisting both creep and oxidation processes.
Abrasion testing demonstrated that nitride-bonded silicon carbide exhibits superior wear resistance compared to special steels designed for use in soil working and padding weld, especially under light to medium soil conditions. Nitride bonded silicon carbide wears out much less intensely than XAR 600 steel, nine times less so than C+Cr+Nb pad weld applications.
IPS Ceramics produces various forms of nitride-bonded silicon carbide products for use as kiln furniture, such as batts, setters, tubes and burner nozzles, beams of various cross sections and beams with different stresses applied up to 1,500 degrees Celsius. Their corrosion-resistance is particularly impressive when dealing with non-ferrous metals.
Corrosion Resistance
Silicon carbide’s strong atomic bonding makes it highly resistant to corrosion from acids and alkalis. Furthermore, a dense oxide layer protects its substrate from attack species.
Nitride-bonded silicon carbide is also extremely durable against heavy loads and impacts, with superior abrasive wear resistance than both steels and cement-bonded ceramic materials in light soil conditions.
NBSiC not only boasts outstanding erosion and corrosion resistance, but it is also resistant to thermal shock shock resistance and chemical instability. Furthermore, this material has proven itself in blast furnace environments to prevent slag formation, alkali corrosion and oxidation; attributes essential for producing iron. NBSiC’s combination of shape-making capabilities with Blasch’s shape memory makes it the ideal material to line bellies, boshes and tuyeres in iron blast furnaces, copper incinerators and kiln furniture applications. Coal, mineral and paper industries as well as chemical plants frequently utilize this product as combustion tube liners due to its excellent erosion-corrosion resistance and thermal shock properties, which extend equipment lifespan while improving performance and lowering operating costs.
Wear Resistance
Silicon nitride boasts high resistance to wear and can withstand mechanical loads under impact, making it chemically stable against most acids and alkalis, offering excellent strength at elevated temperatures as well as thermal shock protection. Furthermore, casting complex shapes is easy while molding can fit to fit into any equipment’s geometry seamlessly.
Nitride Bonded Silicon Carbide can be an ideal material to use in soil working applications as it is more resilient to damage than materials like special steel, boron steel and padding weld. Wear depending on the type of soil mass being worked and its distribution of grain size distribution will ultimately dictate wear levels experienced.
NB SiC features a hard nitride ceramic phase that offers superior resistance against soil particle abrasion, shear forces generated during abrasion and cracking or brittle failure.
