Ordinary ceramics appear white due to light scattered by the pores formed at the intersection of grain boundaries. Murata has greatly reduced the occurrence of pores in highly dielectric ceramics by making denser and more evenly homogenous ceramics through the optimization of production processes, in order to attain higher features. As a result, we have developed transparent ceramics(LUMICERA®). LUMICERA® is anticipated to broaden the horizon for optical materials. CERABRID®, on the other hand, is a free-forming dielectric compound material with good high frequency characteristics, made from a combination of high-frequency dielectric ceramics and resin. It answers the needs of the ubiquitous age by fitting internal antennas into a minute gap in a mobile terminal for design flexibility or functioning as a wearable terminal material. Both of those materials represent new material technology which pioneers a new possibility in ceramics.

The refractive index of the transparent ceramics is 2.08( λ= 587 nm). It is quite high compared with that of conventional optical glasses (between 1.5 to 1.8). Furthermore, as there is no birefringence in the ceramics, there is a potential for downsizing and advancement of optical devices with optical elements, such as lenses.
