Odporność na korozję

Silicon carbide ceramics are widely recognized for their superior corrosion resistance. They can withstand high levels of acids and alkalis as well as hot steam and water in harsh chemical environments without succumbing to corrosion, and have exceptional abrasion resistance properties which make them the go-to choice for wear-resistant applications such as lining cyclones, tubes, ducting chutes hoppers and conveyor systems.

Silicon carbide’s corrosion resistance is determined by several factors, including its ability to form a protective oxide layer and its permeability. SiC is capable of creating thick oxide layers on its surface which prevent direct reactions between attacking species and substrate. This may explain its frequent observation with parabolic corrosion kinetics compared to Si3N4.

Silicon carbide’s corrosion resistance is enhanced by its oxide barrier formation as well as its high fracture toughness – this factor being particularly crucial when used in ballistic situations where impacts cause projectiles to shatter and inter-granular cracking occurs.

Silicon carbide stands out from metals by possessing superior thermal stability and low creep, making it a compelling option for high temperature applications such as gas sealing rings and mechanical seals. Furthermore, its impact-proof properties make it suitable for dynamic sealing technology applications.

Wear Resistance

Silicon carbide is a hard, durable material designed to resist abrasion and impact damage, as well as temperatures up to 1300F (550C), has excellent chemical stability with respect to alkalines and acids, and features superior wear resistance. Because of this property, ceramic linings made of silicon carbide are commonly found inside production systems such as cyclones, tubes, chutes, hoppers and pipes in production lines; typically manufactured into shapes other than flat plates for improved wear resistance and are provided in multiple sizes and designs.

Nitride-bonded silicon carbide was discovered to outperform steel types commonly used for soil working parts when tested for abrasive wear resistance, although this depends on soil conditions; light soil conditions often allow loose sand grains to move freely across friction surfaces of materials under test and micro-cutting may occur, creating an irregular surface finish and leaving an unusually rougher surface finish than with other tested materials.

Silicon carbide ceramics have become an indispensable element in high-temperature furnaces, making it the material of choice for various applications in these furnaces. Applications include tubes, setters and beams for kilns; burners, hot sections and cooling tubes for furnaces; thermal protection sleeves and thermal management sleeves. Its excellent oxidation resistance, high mechanical strength and low creep at elevated temperatures make silicon carbide especially suitable for load bearing applications.

Sintered silicon carbide features excellent thermal conductivity and low thermal expansion characteristics, making it suitable for kiln furniture used in heat treatment, firing and sintering processes where strength, thermal conductivity and dimensional stability are crucial requirements.

Silicon carbide tiles and other refractory ceramic products are widely utilized across numerous applications, from kilns, gas turbines, smelters, to ballistic armor. As its density exceeds those of diamond and boron carbide, silicon carbide stands out as an appealing material for bulletproof vests and other ballistic protection equipment, and is expected to become an alternative choice to titanium in certain ballistic application areas due to its improved strength, durability and ballistic performance.

Przewodność cieplna

Silicon carbide offers excellent thermal conductivity and can withstand temperatures of up to 1600 degrees Celsius, making it a highly desired ceramic nonoxide for applications requiring superior heat resistance and strength – such as mechanical seals, hydraulic piston rods and pump components. Furthermore, its corrosion-resistance makes it perfect for use in acids, alkalis and organic solvents, giving the material hardness comparable with diamond. In addition, toxicological safety allows it to be used safely within food manufacturing industries.

SiC thermal conductivity depends on its purity, phase composition and microstructure. At 300 degK purity levels, SiC can exhibit thermal conductivity approximately half that of pure diamond and significantly greater than copper; however due to the crystaline nature of its crystal and large particle surface area it may be difficult to achieve practical levels without decreasing particle sizes.

Silicon Carbide ceramics can be manufactured through reaction bonding and sintering processes, each having an effectful outcome in terms of microstructure. Reaction bonding involves infiltrating compacts composed of mixtures of SiC and carbon with liquid silicon that then reacts with initial SiC particles to form more silicon carbide; this then bonds the original particles and increases overall density. Sintered silicon carbide on the other hand is produced from pure SiC powder using traditional ceramic forming processes with non-oxide sintering aids; producing more uniform microstructure with capabilities to reach extremely high densities.

IPS Ceramics provides all principal types of sintered silicon carbide refractory ceramic, an extremely versatile and long-lasting refractory that offers excellent thermal shock resistance, low thermal expansion, excellent wear resistance and corrosion resistance, ideal for use in demanding conditions like 3D printing, ballistics production and energy technology. Furthermore it can withstand exposure to many acids like phosphoric, sulfuric, nitric and hydrochloric acids without degradation – as well as being resistant against environmental conditions that contribute to their degradation such as 3D printing!

Load-bearing applications also make excellent use of this material, especially those requiring strength at higher temperatures such as car brake pads. We produce various components including batts, setters, beams, props and rollers in this material to meet your specific requirements, in addition to offering kiln furniture capable of sintering up to 1650oC sintering temperatures.

Due to this hardness and its malleability, silicon carbide makes for an invaluable industrial material that is moldable into nearly any shape imaginable. Furthermore, silicon carbide can withstand high temperatures as well as chemical attacks from phosphoric, sulphuric and hydrochloric acids, making it one of the key elements in hard armour production for light to medium threats.

SiC is known for its superior fatigue resistance, making it suitable for ballistic applications due to repeated impacts at high velocities. Furthermore, its low thermal expansion coefficient and high Young’s modulus help minimize abrasion. Furthermore, SiC can withstand erosion, corrosion, high temperatures, borehole fluids as well as borehole fluids for maximum protection – making it the ideal material choice for ceramic sand filters in oil drilling operations.

SiC is used in an array of products, ranging from high heat duty kiln shelves and components for chemical plants to mills and expanders. Silicon carbide ceramics boast exceptional resistance against abrasion, wear and erosion as well as having great frictional properties; furthermore their high temperature tolerances, resistance to chemicals including acidic lyes and low thermal expansion make them well suited for construction applications.

Sintered silicon carbide SSiC and silicon infiltrated SiSiC are widely used as load-bearing materials that must withstand extreme end-use temperatures, making these crystalline structures perfect for shafts, bearings and nozzles.

Reaction bonded SiC (RBSC), on the other hand, boasts almost full density. To create it, this ceramic can be manufactured using porous carbon-rich feedstock which is then infiltrated with molten silicon via dry pressing or extrusion methods – enabling complex large-scale SiC ceramic production.

Silicon carbide boasts an exceptionally high Mohs scale rating of 9.5, making it one of the hardest ceramic materials on the market.
