Brief: Discover the premium Grown Sapphire Crystal Boule, crafted using the KY Kyropoulos method, weighing 80kg-300kg. Ideal for optical device manufacturing, this synthetic single crystal alumina offers unmatched hardness, light transmission, and chemical stability for high-end applications.
Related Product Features:
  • Synthetic single crystal alumina (α-Al₂O₃) with Mohs hardness 9, second only to diamond.
  • Wide light transmission range from ultraviolet to infrared (0.15~5.5μm).
  • Excellent chemical stability, resistant to acids, alkalis, and radiation.
  • High thermal properties with a melting point of 2050℃ and thermal conductivity of 35W/(m*K).
  • Available in common sizes of 2-12 inches diameter for versatile applications.
  • Used in semiconductor, optical, consumer electronics, and industrial fields.
  • Customizable with coatings like AR, HR, or filter films for specific band optimization.
  • Precision machining options include wafers, optical windows, and shaped parts.
Faqs:
  • What is the primary use of a sapphire crystal boule?
    Sapphire crystal boules are primarily used to produce high-performance optical components, LED substrates, and scratch-resistant cover glass for consumer electronics.
  • Why is sapphire crystal considered expensive?
    Sapphire crystal is costly due to its extreme hardness requiring specialized cutting/polishing and high-purity growth processes like the Czochralski method.
  • What are the thermal properties of sapphire crystal boules?
    Sapphire crystal boules have a melting point of 2050℃, thermal conductivity of 35W/(m*K), and a coefficient of thermal expansion of 5.8×10⁻⁶/K, making them highly resistant to thermal shock.
