N-9000NS

Translucent Alumina Ceramics which Nishimura Advanced Ceramics manufactures is high-intensity ceramics. It has high total light transmittance; thus it has a superiority of light translucency.

As N-9000NS is produced from pure fine-grain Alumina, it has a higher intensity than other translucent aluminas.

It can be used as a substitute material for sapphires for its high intensity.
