**Market Insight:** Custom-engineered PBN is the fastest-growing segment. Semiconductor manufacturers require ultra-precise components for crystal growth and wafer handling, driving innovation.

**Trend:** Research institutions and universities are key to early-stage development, with their prototypes later adapted for industrial use.

### 1.4. High-Density PBN Plates
High-density PBN offers enhanced structural integrity and mechanical stability under repeated thermal cycling. This is critical in crystal growth crucibles and high-temperature reactors where thermal shock resistance is paramount.

**Market Insight:** High-density PBN is in strong demand from the semiconductor industry, especially with the rise of wide-bandgap semiconductors like SiC and GaN.

**Trend:** Manufacturers are scaling up production to meet volume demand from Asia-Pacific fabs, where next-generation chip manufacturing is expanding rapidly.
