Product Introduction
YSZ (Yttria Stabilized Zirconia) Transparent Ceramic boast a refractive index as high as 2.16 in the visible light range—surpassing that of conventional optical glasses and resins—making them ideal for crafting optical lenses and enabling the miniaturization of digital devices. Additionally, YSZ transparent ceramics exhibit excellent transmittance across both the visible and mid-infrared spectra, with a transmission range spanning from 250 nm to 7,500 nm. They also offer superior durability, resisting wear, acid and alkali corrosion, and even harsh rainwater exposure, positioning them as an outstanding material choice for applications such as transparent armor, infrared windows, and radomes.
Key Advantages
- High refractive index in the visible light range
- Excellent transmittance
- High toughness, high flexural strength, and excellent wear resistanceApplication Areas
- Transparent ceramic armor
