Key Materials & Applications
- Aluminum Oxide (Al₂O₃): The industry workhorse. Offers excellent electrical insulation, good mechanical strength, and high wear and chemical resistance. Ideal for substrates, insulators, seals, and wear-resistant components.
- Aluminum Nitride (AlN): The thermal management champion. Features very high thermal conductivity combined with excellent electrical insulation. Perfect for heat sinks, semiconductor substrates, and LED packages.
- Zirconia (ZrO₂): The toughness leader. Known for its high fracture toughness and strength, often called "ceramic steel." Excellent for medical components, cutting tools, and precision parts subject to mechanical stress.
- Silicon Carbide (SiC): The extreme environment performer. Offers outstanding thermal shock resistance, high hardness, and maintains strength at ultra-high temperatures. Used in kiln furniture, abrasives, and advanced refractories.
- Silicon Nitride (Si₃N₄): The robust all-rounder. Combines high strength, good fracture toughness, and excellent thermal shock resistance. Common in bearings, cutting tools, and automotive components.

Material Selection Guide: Find Your Perfect Match
- For Superior Electrical Insulation & Cost-Effectiveness:
Recommended: Alumina (Al₂O₃)
Why: With volume resistivity >10¹⁶ Ω·cm and excellent dielectric strength, it's the ideal choice for high-voltage insulators, circuit substrates, and electronic housings.
- For Maximum Heat Dissipation:
Recommended: Aluminum Nitride (AlN) or Silicon Carbide (SiC)
Why: AlN provides the best combination of high thermal conductivity (up to 180 W/m·K) and electrical insulation. SiC offers high conductivity and exceptional strength in extreme environments.
- ** For High Mechanical Strength & Toughness:**
Recommended: Zirconia (ZrO₂)
Why: Zirconia's exceptional fracture toughness (up to 7 MPa·m⁰·⁵) and high flexural strength make it resistant to cracking and mechanical shock, perfect for demanding structural applications.
- For Static Dissipation (ESD-Safe) & Machinability:
Recommended: Conductive Ceramics (ESD Series) or ITA
Why: These materials bridge the gap between insulating ceramics and metals. They safely dissipate electrostatic charges, protecting sensitive electronic components during handling and processing.
