Silicon Carbide (Sintered SSiC) vs Zirconium Oxide (Zirconia) Y-TZP
Side-by-side chemical composition and mechanical property comparison.
Overview
Silicon Carbide (Sintered SSiC)
Pressureless sintered alpha-silicon carbide (SSiC). One of the hardest and lightest engineering ceramics (density 3.1 g/cm³). Exceptional thermal conductivity (120 W/m·K), very high compressive strength (3900 MPa), hardness 2800 HV, and outstanding chemical inertness. Maintains strength to 1650°C. Semiconductor (variable resistivity). Applications: mechanical seals, bearings, pump components, kiln furniture, semiconductor furnace parts, ballistic armor, brake discs.
Zirconium Oxide (Zirconia) Y-TZP
Yttria-stabilized tetragonal zirconia polycrystal (3Y-TZP). The toughest engineering ceramic with transformation toughening mechanism. Exceptional flexural strength (900–1200 MPa), high fracture toughness (5–10 MPa·m½), density 6.05 g/cm³, elastic modulus ~200 GPa. Low thermal conductivity (2–3 W/m·K) makes it a good thermal insulator. Applications: precision bearings, cutting blades, dental implants, fuel cell components, wear-resistant parts, thread guides.
