Sapphire Blank Introduction

 

 

​​Sapphire Blank 118mm×74mm×8mm High Hardness for Infrared Windows​​

 

 

 

Sapphire blanks/substrates refer to square or circular plate-like materials obtained by orienting, cutting, and rough grinding large-sized sapphire boules. They have not yet undergone final precision polishing (CMP) or patterning processes and serve as intermediate semi-finished products for manufacturing various sapphire end products, such as wafers, optical windows, and cover plates. The core material is α-aluminum oxide (α-Al₂O₃) single crystal with a regular lattice structure.

 

 

ZMSH Services Introduction: We specialize in the research, development, and manufacturing of high-performance crystal materials. In addition to providing sapphire blanks/substrates in various specifications, our company possesses strong precision machining capabilities to produce sapphire wafers (for LEDs and Micro-LEDs), sapphire optical windows/domes (for photoelectric equipment and military applications), sapphire rods/tubes (for semiconductor equipment chamber liners), and custom-shaped sapphire components according to customer drawings. We are committed to offering a one-stop solution from crystal growth to precision processing.

 

 


 

Sapphire Blank Characteristics

 

 

  1. Extreme Hardness and Wear Resistance: Sapphire blank mohs hardness of up to 9, second only to diamond, making it highly scratch-resistant and extremely durable.
  2. Excellent Optical Performance: Sapphire blank high transmittance across ultraviolet to infrared wavelengths (0.15–5.5 μm), making it an ideal material for optical windows.
  3. Outstanding Physical and Chemical Stability: Sapphire blank high-temperature resistance (melting point of 2053°C), thermal shock resistance, and strong chemical inertness. Insoluble in strong acids and alkalis except hydrofluoric acid and hot phosphoric acid.
  4. Good Electrical Insulation and Dielectric Properties: An excellent insulator with stable dielectric constants.
  5. High Purity and Low Defect Density: Sapphire blank as a single-crystal material, it has minimal internal defects and extremely high purity, ensuring no contamination in process environments.
