Advanced Ceramic Materials Overview
Advanced ceramic materials, also known as technical ceramics, are high-performance inorganic, non-metallic materials designed for extreme industrial applications. These ceramics surpass traditional materials in thermal stability , mechanical strength, and corrosion resistance. Main technical ceramic compositions include alumina (Al₂O₃), zirconia (ZrO₂), and aluminum nitride (AlN), optimized for industries like aerospace, semiconductors, and biomedical engineering.

Traditional Ceramics |
Advanced Ceramics |
| Raw Materials | Natural minerals, used directly without treatment | Highly selected raw materials, artificial synthesis |
| Structure | The microstructure is coarse, uneven, and porous | Uniform and fine microstructure |
| Preparation Process | Low sintering temperature, no processing required after sintering | The sintering temperature is high and processing is required after sintering |
| Product Performance | Limited to daily life and construction use | Excellent physical, chemical and other properties, industrial fields |
The commonly ceramic forming processes for technical ceramics include isostatic pressing, dry pressing, tape casting,hot die casting, extrusion forming, injection molding,slip casting, etc. The initial blank is sintered to densify the internal structure. In order to achieve the product dimensional accuracy required by customers, diamond tools are sometimes required for grinding.

| Accuracy | 0.2 | ±0.005 | 0.01~0.2 | 0.001/100 | ±0.002 | 0.005/100 | ±0.001 |
Advanced ceramics outperform metals due to their superior hardness and thermal shock resistance. For example, zirconia plungers in hydraulic systems reduce wear by 90% and operate at 1,500°C without deformation, unlike steel, which oxidizes above 500°C. Their low density (5.7–6.0 g/cm³) also minimizes energy loss in rotating machinery, as seen in aerospace turbines.
In semiconductor production, alumina ceramics provide electrostatic dissipation (ESD) protection with volume resistivity of 1*1013~1014 Ω.cm, preventing wafer contamination. Precision components like ceramic shafts (roundness: 2×10⁻³ mm) ensure alignment in lithography systems. Si₃N₄ etch-resistant plates extended tool lifespan by 70% in plasma etching chambers.
