Hexagonal Boron Nitride (h-BN) vs Zirconium Oxide (Zirconia) Y-TZP
Side-by-side chemical composition and mechanical property comparison.
Overview
Hexagonal Boron Nitride (h-BN)
Hot-pressed hexagonal boron nitride — "white graphite". Unique among ceramics: soft (Mohs 2), easily machinable with conventional tools, self-lubricating. Excellent thermal shock resistance, high-temperature stability (2800°C in inert atmosphere). Good thermal conductivity (30–60 W/m·K) combined with outstanding electrical insulation. Anisotropic properties. Not wetted by most molten metals. Applications: BN crucibles for metal melting, break rings for continuous casting, high-temp insulators, evaporation boats, plasma-resistant parts, solid lubricant.
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.
