CoorsTek Introduces New PhaseSiC™
CoorsTek (Golden, CO, USA), one of the world's largest technical ceramics manufacturers, has introduced its new PhaseSiC™ hybrid liquid-phase silicon carbide material developed specifically for severe service oil & gas seal and valve applications.Specifically, this new material provides nearly twice the elastic modulus of a traditional alumina material at 420 GPa (ASTM-C848) and compressive strength of 3600 MPa (ASTM-C773) – an 80% improvement over traditional alumina and 20% improvement over typical direct-sintered silicon carbide. This fine-grained material is also extremely dense (3.20 gm/cc – ASTM-C20), exhibits superior fracture toughness (5.6 Mpa/m^0.5) – a 30% increase over typical sintered silicon carbide – and provides impressive flexural strength at 480 MPa (ASTMC1161).
Material applications include high speed, non-contacting gas seals (10,000 RPM), gas seal rings, aircraft seals, rotary valves and other severe wear components.
"We developed the PhaseSiC™ material specifically for severe-service oil and gas seals and seal rings," stated CoorsTek Energy Group Sales Director, Lloyd Sobel. "Every aspect of the material was carefully considered and engineered – from raw material formulation to final processing stages. The result is a unique material specifically tuned for exceptional performance and durability."
