Aluminium Nitride vs Zirconium Oxide (Zirconia) Y-TZP
Side-by-side chemical composition and mechanical property comparison.
Overview
Aluminium Nitride
Non-oxide ceramic with the highest thermal conductivity among electrical insulators (170–230 W/m·K). Excellent dielectric properties, CTE closely matching silicon wafers (4.5×10⁻⁶/K). Density 3.3 g/cm³, flexural strength 300–400 MPa, hardness 11 GPa. Alternative to toxic BeO in semiconductor packaging. Applications: power electronic substrates (IGBT, MOSFET), LED heat sinks, laser diode mounts, microwave components, electrostatic chucks.
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.
