## Part III: 2026 Procurement Strategy

### 3.1 Advanced Ceramics Parts Strategy

1. **Phased validation**: Start with small batch (50-100 pcs) to verify dimensional accuracy and yield, then sign annual framework agreement
2. **Technical binding**: Require suppliers to provide material traceability certification (from powder to finished product)
3. **Alternative sourcing**: Qualify 2-3 suppliers simultaneously to avoid single-source risk
4. **Domestic substitution path**: Start with non-critical parts, gradually advance to core etch chamber components

### 3.2 Aerogel Material Strategy

1. **Application matching**: Select aerogel type based on service temperature (<650°C: SiO₂; >650°C: ceramic fiber composite)
2. **Thickness optimization**: Determine minimum effective thickness via thermal simulation to reduce procurement cost
3. **Long-term agreement**: Aerogel raw material prices fluctuate significantly; recommend 6-12 month price lock agreements
4. **Localized service**: Prioritize suppliers with local warehousing at project site to shorten lead time

## Part IV: Risk Warnings

1. **Advanced Ceramics**: High-end products (purity >99.99%) still rely on imports (Japan’s Kyocera, Germany’s CeramTec); domestic substitution requires time
2. **Aerogel**: Low-end capacity oversupply; high-end products (super-hydrophobic, flexible aerogel) have high technical barriers
3. **Geopolitics**: US export controls on semiconductor equipment to China may indirectly affect terminal demand for advanced ceramic parts

## Part V: Conclusion

China’s advanced ceramics for semiconductor applications and aerogel insulation material industries have entered a rapid growth phase in 2026. When selecting Chinese suppliers, procurement professionals should focus on:

– Material purity and consistency (advanced ceramics)
– Thermal conductivity and long-term durability (aerogel)
– End-customer certification status (applies to both)

Procurement professionals are advised to complete supplier audits and sample validation before Q3 2026 to secure production capacity and pricing for year-end.
