Experience Unmatched Durability With Sintered Silicon Carbide Components
Reaction sintered silicon carbide (SSiC) is an advanced industrial ceramic with unrivaled properties, such as its exceptional strength and hardness, strong acid and alkali corrosion resistance, thermal stability and exceptional heat transfer resistance.
SSiC is an excellent material to use in kiln furniture for intermediate frequency casting applications such as electric furnace heat treatments or metallurgical sintering applications, providing precise dimensional control with low thermal expansion rates and superior creep resistance at elevated temperatures. It is also highly resistant to creep.
High-Temperature Resistance
Silicon carbide has the capacity to withstand high-temperature environments without breaking a sweat, thanks to the sintering process that transforms it into an indestructible ceramic material with superior thermal shock resistance, oxidation resistance, corrosion protection and thermal shock absorption capabilities. As such, silicon carbide makes an excellent material choice for industrial applications like thermocouple protection tubes, tunnel kilns, shuttle or roller kilns, gas/fuel furnaces as well as power generation equipment.
Reaction sintered SiC is an extremely dense yet lightweight product with exceptional strength and durability in hostile environments. It boasts exceptional abrasion- and erosion-resistance, chemical inertness, excellent creep resistance properties and can even be used with acids or alkalis without issue.
Sintering aids are experiencing tremendous global growth as industries turn toward energy efficiency and advanced materials. North America is an especially vibrant region for this industry due to a robust manufacturing sector and emphasis on environmental responsibility – both of which will fuel further expansion of solid-state sintered silicon carbide market as manufacturers search for solutions that combine economic success with ecological responsibility.
Thermal Shock Resistance
Silicon carbide is an extremely hard synthetic material, boasting a Mohs hardness rating of 9. It boasts very high strength and abrasion resistance as well as great corrosion and wear resistance properties.
Plastic is an excellent construction material because it resists corrosion, erosion and frictional wear as effectively as its mechanical seal counterpart. Furthermore, its thermal expansion tendency is minimal while its low Young’s modulus (a measure of elastic flexibility) means it can withstand extreme pressure without warping.
GAB Neumann manufactures sintered silicon carbide components of various structural shapes through sintering using reaction-sintered CORESIC(r) ceramics formed through cold isostatic pressing or extrusion, using reaction-sintered CORESIC ceramics formed through cold isostatic pressing or extrusion. Sintering ensures CORESIC ceramic has superior corrosion, wear and fracture toughness making it suitable for demanding industrial applications; ballistic armour plates made of CORESIC ceramic can absorb impact energy while remaining lightweight; helping military and law enforcement personnel keep mobility when deployed against potential threats.
Corrosion Resistance
Sintered Silicon Carbide components can withstand various chemicals and environments with ease, including hydrochloric, sulfuric and hydrobromic acids as well as bases such as amines and potash as well as solvents and oxidizing agents such as nitric acid.
Sintered silicon carbide’s corrosion resistance is dictated by its microstructure and grain boundary layers, while CVD sintered silica ceramics offer greater corrosion protection compared to reaction-bonded silicon carbide.
SSiC’s production process uses pressureless technology for enhanced durability. This makes it ideal for applications in chemical production, aerospace and power generation applications as it has long meter life expectancies that withstand rotation, sliding and abrasion stresses. Furthermore, mechanical seals, pumps and nozzles made from sintered silicon carbide are often found on high-speed aircraft as its excellent thermal shock resistance and temperature stability allows greater aircraft efficiency and performance; its low density saves weight to enhance overall efficiency and performance.
Wear Resistance
Silicon Carbide is an extremely hard ceramic material with a Mohs hardness rating of 9, just behind diamond. Due to this quality, it withstands both impact and abrasive forces well, making it suitable for use in grinding wheels, blasting media, precision-machined components subject to high stresses as well as precision grinding applications.
Silicon carbide’s strength lies in its corrosion resistance. It can withstand exposure to harsh chemicals like hydrochloric and sulfuric acids without experiencing significant degradation, making it ideal for semiconductor production equipment, lasers and structural components in fusion reactors.
Hexoloy SE is a dense form of silicon carbide created through pressureless sintering that offers precise dimensional control, low temperature expansion and no free silicon content – ideal characteristics for ballistic armour plates that meet national military specifications for protection from high-velocity projectiles.
