AION (Aluminum Oxynitride) ceramic, abbreviated as AlON ceramic, is a transparent polycrystalline material.
Product Introduction
AION (Aluminum Oxynitride) ceramic, abbreviated as AlON ceramic, is a transparent polycrystalline material—a cutting-edge polycrystalline infrared material that exhibits exceptional optical transparency across the visible to mid-infrared spectrum. Its standout advantage lies in its optical isotropy, combined with outstanding transmittance in the mid-infrared range. Additionally, AION ceramic boasts excellent physical, mechanical, and chemical properties, making it the preferred material for applications such as missile radomes, infrared windows, and bulletproof armor.
Key Advantages
- High optical transmittance from visible to mid-infrared wavelengths
- Excellent mechanical strength and good thermal shock resistance
- High transparency and lightweight design
- High-temperature resistance and antioxidant properties
- Durability and impact resistance
- Lower production costs and easy preparation of large-size, custom-shaped devicesApplication Areas
- Military sector
- Aerospace
- Missile fairing
- Preferred materials for infrared windows and bulletproof armorProduct Features
