Industrial Ceramic Components
1. Material Definition & Classification
Industrial ceramics are inorganic, non-metallic materials engineered for extreme environments. Primary categories include:
Oxide Ceramics: Al₂O₃ (alumina), ZrO₂ (zirconia)
Non-Oxide Ceramics: SiC (silicon carbide), Si₃N₄ (silicon nitride)
Composite Ceramics: ZTA (zirconia-toughened alumina), AlN (aluminum nitride)

2. Core Properties
Mechanical: Vickers hardness up to 2,500 HV (SiC), flexural strength exceeding 1,200 MPa (Y-TZP zirconia)
Thermal: Thermal shock resistance (ΔT> 500°C for Al₂O₃), low CTE (4×10⁻⁶/°C for Si₃N₄)
Electrical: Dielectric strength> 10 kV/mm (99.6% alumina), semiconductor behavior (SiC)
Chemical: Inert to acids/alkalis (except HF for SiO₂-based ceramics)
3. Manufacturing Processes
Forming: Dry pressing (for simple geometries), injection molding (complex shapes), slip casting (large components)
Sintering: Conventional (1,600°C for alumina), HIP (hot isostatic pressing for pore-free structures)
Finishing: Laser machining (±0.01 mm tolerance), diamond grinding (Ra < 0.1 μm)

Thermal Management Systems
Alumina (Al₂O₃): Insulating substrates for power electronics (e.g., IGBT modules) with CTE matching capabilities (7.2×10⁻⁶/°C)
Aluminum Nitride (AlN): High thermal conductivity (180 W/m·K) for LED heat sinks in automotive lighting
Mechanical Wear Resistance
Zirconia-toughened alumina (ZTA): Mining equipment liners with 3× longer service life than manganese steel
Silicon Carbide (SiC): Seal rings for chemical pumps, achieving 300°C vs. superalloys)
Emerging applications encompass 5G antenna radomes (low dielectric loss ceramics) and hydrogen energy (proton-conducting ceramics for electrolyzers). These materials are increasingly processed via additive manufacturing (DLP/SLS) to achieve complex geometries with ±25 µm dimensional accuracy.
