Transparent & Translucent Ceramics

These ceramics are showing remarkable mechanical, thermal, chemical and optical properties. Baikowski® provides dedicated raw material such as Spinel, High Purity Alumina or YAG.

Ask for information

What are transparent & translucent ceramics?

Transparent ceramics are polycrystalline non-birefringent materials such as spinel or YAG. Transparency could be also achieved by monocrystalline birefringent materials such as sapphire.YAG transparent ceramic piece

Translucent ceramics are polycrystalline birefringent aluminas, meaning that there are several diffraction angles for a same wavelength. Translucent ceramics are mostly made of alpha alumina, such as CR or TCPLS.

Properties

Transparent & translucent ceramics have remarkable properties:

  • Optical functions: transparent ceramics have excellent transmission properties. As for translucent ceramics, they have efficient diffusion properties. Baikowski® powders are optimized for optical functions in the final ceramics, as we control the purity, formulation for sintering process, and the size of particles to ensure the highest density ceramic parts.
  • Mechanical strength and hardness: Spinel parts can be used in armor windows. Our spinel products have a constant crystallographic composition with low sulfur content and low metallic impurities. It ensures the best transparency and mechanical properties for your ceramic parts.
  • Chemical stability: like most of ceramics.
  • Thermal resistance: translucent and transparent ceramics are stable even at temperatures up to 1,600°C. In comparison, glass is already reacting at 550°C.

Those properties are strengthened by Baikowski’s control of particle size & size distribution in the delivered products. Moreover, we can dope our products on request in order to add intended properties for your final ceramic parts.
Seeing the upper properties, those ceramics are used for transparent/translucent applications in extreme conditions.
