Core Material & Key Properties

• Primary Materials: High-purity alumina (Al₂O₃ ≥99.7%), zirconia (ZrO₂), silicon nitride (Si₃N₄), and boron nitride (BN) — selected for low impurity content (ppm-level) to avoid contaminating semiconductors or PV wafers.
• Critical Performance Traits:
  1. Ultra-high temperature resistance (sustains 1200–1800℃ for long periods, withstands thermal shock).
  2. Excellent chemical inertness: Resists corrosion from gases (e.g., hydrogen, argon) and molten materials in furnaces.
  3. Low thermal conductivity & high insulation: Prevents heat loss and ensures electrical safety in high-voltage furnace environments.
  4. Dimensional stability: Minimal thermal expansion to maintain precision during repeated heating/cooling cycles.

Common Product Types & Applications

• Furnace Liners/Chambers: Form the inner wall of PV semiconductor furnaces, isolating the processing area from external contamination.
• Crucibles & Boats: Hold raw materials (e.g., silicon ingots, semiconductor wafers) during annealing, diffusion, or deposition processes.
• Rotors & Blades: Used in gas mixing or wafer handling systems within furnaces, requiring high precision and wear resistance.
• Supports & Fixtures: (e.g., ceramic shelves, pins) Secure wafers or components during high-temperature processing, ensuring uniform heat distribution.

Core Advantages for PV Semiconductor Industry

1. Ensures product purity: Low impurity emission prevents defects in semiconductors or PV cells.
2. Extends furnace service life: Resists wear, corrosion, and thermal fatigue better than metal alternatives.
3. Enhances process stability: Consistent performance reduces production downtime and improves yield.
