Pressureless sintering utilizes high temperatures and pressures to transform powdered material into stiff, dense components, creating fully dense ceramic materials with incredible strength.
Aerospace
Mersen products meet these stringent demands with ease and provide long-term reliability in aerospace applications. By selecting suitable materials, safety, efficiency and life extension are ensured – such as graphite and sintered silicon carbide products from Mersen.
Sintered sic thermocouple protection tubes from our company provide sensors in harsh environments with protection from harmful gases and particles by absorbing any corrosive gas emissions and shielding against temperature extremes to prevent sensor failure, thus cutting maintenance costs.
SSiC’s lightweight nature makes it an excellent material choice for aerospace applications where energy efficiency and weight reduction are primary goals. Our Boostec(r) silicon carbide wear plate improves sliding contact applications through using spherical pores to provide product lubrication on friction surfaces.
Automotive
Silicon carbide boasts a high modulus of elasticity and exhibits excellent dimensional stability. Furthermore, it’s highly resistant to corrosion as well as high temperatures and thermal shock; qualities which make it perfect for gas sealing rings, mechanical seals and bearings used under harsh conditions.
Silicon Carbide is an ideal semiconductor material for power electronic devices in electric vehicles (EVs), helping reduce weight and size while increasing performance and efficiency. It boasts superior high-speed switching performance, higher breakdown field depth, lower stray inductance levels, and better thermal conductivity than traditional silicon.
Black Silicon Carbide powder is widely utilized across industries such as aerospace, automotive and glass for precision lapping and polishing to achieve precise dimensions with smooth finishes. Available on universal-based carriers or oil-based carriers and boasting the ideal balance of hardness, durability and thermal conductivity; one of only three materials known to man only exceeded by diamond and cubic boron nitride in terms of hardness. Easily cut using flame cutting or water cutting processes it has proven extremely successful metallurgical applications as well.
Chemical Processing
Silicon carbide’s resistance to corrosion when exposed to liquid and gaseous chemicals of different pH values make it a suitable material for chemical processing applications, including blast furnaces and incinerators. Hexoloy SE tubes protect thermocouples in harsh environments by shielding them from harmful gases and particles for accurate temperature readings and sensor longevity.
Premium sintered silicon carbide products are perfect for process equipment sealing applications due to their superior wear and strength properties compared with metals, providing greater wear resistance as well as high thermal conductivity and chemical stability in extreme end use temperatures.
Morgan’s Hexoloy SSiC and Reaction Bonded Silicon Carbide (RBSiC) ceramics come in numerous shapes and sizes, from tubing and plates to tubing. These highly engineered materials can be formed through cold isostatic pressing/extrusion techniques before being sintered in an inert atmosphere using either boron carbide or carbon as additives to facilitate particle diffusion while preventing oxidation.
Oil & Gas
Silicon carbide is well known for its outstanding wear and corrosion resistance in harsh environments. A short conversation with an engineering specialist will quickly establish whether this remarkable material meets your application requirements for high strength, low density and tribological performance in aggressive media with extreme temperature variations.
Silicon Carbide can be produced using either reaction sintering or pressureless sintering processes, with reaction sintering employing alpha SiC with a Wurtzite crystal structure sintered with additives like boron and carbon; pressureless sintering uses fine SiC powder combined with sintering aids to create porous ceramic products with higher flexural and high temperature strength than their reaction counterparts.
Combine a-SiC and its accompanying sintering aids with a porous macroporous support like carbide, graphite or alumina for superior tribological properties for sealing components used in pumps, blasting nozzles or chemical reactors. Furthermore, surface oxidation steps may be applied afterwards in order to remove any free carbon that may have formed during the sintering process.
