There are 2 types of silicon carbide, the one is directly sintered silicon carbide(SSiC), another one is reaction-bonded silicon carbide(RBSiC) . SSiC can withstand higher temperature and pressure than RBSiC. Besides, Silicon carbide offers superb wear resistance, chemical stability, it's an ideal choice for ceramic seals in the sealing system.   The ceramic seal ring plays a key role in water, oil, gas sealing system, we always ensure that we manufacture the best-quality products through strict quality control in every process, we introduced KPI into our manufacturing flow chart and keep all batches with consistent dimensions.  We offer a variety of customized and standard seal ceramic rings from prototyping to massive production. All these ceramic seal rings are widely used in a different water pump, gas & oil production, chemical & petrochemical, refinery, power, pharmaceutical, and so on. The gallery of ceramic sealsRemark:We produce a variety of technical ceramic seals in different materials, also different types of ceramic seals, including ceramic sealing disc, ceramic seal ring, ceramic seat, ceramic ball valve.   Technical Datasheet of the ceramic sealing discPropertyUnitsMaterials99.5%Al2O399%Al2O395%Al2O3SiCSi3N4Densityg/cm3≥3.85≥3.80≥3.60≥3.21≥3.2Water absorption%00000HardnessHV17001700150025001550Flexural strengthMpa≥379≥338≥320≥550≥600Compressive strengthMpa≥2240≥2240≥2000≥3306≥2500Fracture toughnessMpa m1/24-54-53-436Max. service temperature(Non-loading)ºC16751600150016001200CTE (20-800ºC)1×10 -6 /ºC6.5~8.06.2~8.05.0~8.03.7~43.1Thermal shockT(ºC)≥250≥200≥220   ------≤1000Thermal conductivity(25ºC)W/m.k30292415015~20Volume resistivity (25ºC )ohm.cm>1 x 10 14>1 x 10 14>1 x 10 14>1 x 10 5>1 x 10 12Insulation strengthKV/mm191818 -------    -------Dielectric constant(1Mhz)(E)9.79.59.5  -------    --------Our advantage and strength1. 10+ Years of manufacturing experience in OEM, ODM and trusted & professional teams 2.
