SiC Seal Ring
Semicorex SiC Seal Rings are designed to perform well in harsh conditions as mechanical seals, suitable for a variety of sealing applications.
Properties of Materials of Semicorex SiC Seal Ring
Applications needing long-lasting sealing solutions are best suited for silicon carbide (SiC), which is well known for its remarkable toughness and chemical resistance.
Integrity of Structure and Chemical Resistance
In order to maintain a dependable seal even under trying circumstances, SiC Seal Rings are mostly used to stop corrosive materials, water, and oil from escaping. When silicon carbide is subjected to temperatures of about 1300°C in an oxygen-rich atmosphere, one of its main characteristics is its capacity to create a protective coating of silicon dioxide. This layer offers strong defense against corrosive substances by strengthening the material's resistance to additional chemical reactions.
Excellent Density and Hardness
Among the hardest materials on the market, silicon carbide ranks just below diamond, cubic boron nitride, and boron carbide with a Mohs hardness of 9.5 and a Knoop hardness between 2670 and 2815 kg/mm². Its mechanical strength and resistance to abrasion are attributed to its uniform density of roughly 3.20 g/mm³ across different silicon carbide crystals, which guarantees a long service life of these seal rings under abrasive conditions.
Mechanical Properties and Covalent Bonding
Pauling's electronegativity calculation indicates that silicon carbide has only around 12% ionic character due to its strong covalent bonds, which provide the material exceptional hardness, a high elastic elasticity, and exceptional wear resistance. Because of these characteristics, SiC Seal Rings are dependable for preserving structural integrity and successfully stopping leaks under high stress situations.
Types of Ceramics Made of Silicon Carbide
We provide two types of silicon carbide ceramic material for these seal rings: SiSiC (SiSiC) and SSiC (Sintered Silicon Carbide). SSiC is produced by sintereding high-purity, nano-grade raw powders at temperatures between 2100°C and 2200°C. The material is densified and shrinks by about 20% as a result of this process, improving its strength, density, and resistance to oxidation and corrosion. A more affordable choice for applications with less stringent performance requirements, SiSiC is made using micron-sized silicon carbide powder and sintered at 1450°C to 1700°C without shape shrinking.

Uses for Mechanical Seals
Gas and Oil Sealing
Leak prevention is essential in the oil and gas industry for operational and environmental reasons. Our SiC Seal Rings provide dependable defense against gas and oil leaks, protecting equipment and pipeline integrity. These seals are perfect for the tough conditions that are typical of this industry because of silicon carbide's strong mechanical strength and chemical resistance.
Prevention of Water and Corrosion
SiC Seal Rings offer an efficient barrier that stops leaks and the entry of impurities in applications involving water and caustic media. The seal rings' durability and reduced maintenance requirements are further enhanced by their capacity to continue operating in chemically demanding settings.
Applications at High Temperatures
Our SiC Seal Rings are appropriate for applications where thermal stability is a concern since silicon carbide resists high temperatures. These seal rings provide continuous operation and minimize downtime by performing dependably in conditions where heat could destroy other materials.
A variety of silicon carbide goods, such as moving rings, static rings, flat rings, swivel rings, middle groove rings, shafts, bushings, and anti-ballistic plates, are our specialty at Semicorex. Our dedication to quality and innovation guarantees that our SiC Seal Rings satisfy the exacting requirements of contemporary industry, offering reliable sealing solutions that improve dependability and performance.
