Unpolished Sapphire Rod Single Crystal Al₂O₃ Optical & Industrial Components
Product Overview:
High-purity single crystal sapphire rods (Al₂O₃, 99.999%) are engineered for advanced optical, semiconductor, and industrial applications requiring exceptional hardness, thermal endurance, and chemical stability. Produced through the Kyropoulos (KY) or Pulling-Down (PD) methods, these sapphire rods feature uniform lattice orientation, high precision, and excellent mechanical integrity.
With outstanding optical transmission from UV to IR, high wear resistance, and the ability to operate continuously in environments exceeding 2000°C, sapphire rods are widely used in optical instruments, semiconductor equipment, LED manufacturing, high-temperature furnaces, laser systems, and precision mechanical components.
Custom diameters (down to 0.3 mm), lengths (up to 600 mm), and crystal orientations are available to meet specialized engineering, research, and industrial requirements.
Ultra-high purity monocrystalline Al₂O₃ (99.999%)
Mohs hardness 9 — extremely wear-resistant and scratch-resistant
Thermal stability up to 2000°C with low thermal deformation
Excellent optical transparency (0.17–5.5 μm, UV–IR)
Chemical & plasma resistance against acids, alkalis, molten metals, gases
High dielectric strength for electronic and RF applications
Customizable in size, orientation, finishing, and geometry

1. What makes sapphire rods suitable for high-temperature applications?
Sapphire maintains crystal integrity up to 2000°C, offering low thermal expansion, high strength, and chemical inertness under extreme heat.
2. Are sapphire rods resistant to corrosion and plasma?
Yes. Sapphire is inert to acids, alkalis, plasma, and most molten metals, making it ideal for semiconductor chambers and harsh-chemistry environments.
3. Can sapphire rods be customized?
Yes. Custom diameters, lengths, polished surfaces, crystal orientations, and complex shapes are available to meet optical, semiconductor, and mechanical requirements.
