Electronic ceramics is one of the world's leading fields in Japanese industry. Ceramics generally refers to pottery or porcelain made by sintering powder as a raw material. Especially, what is called electronic ceramics is ceramics in which the behavior of electrons such as insulation property, conductivity property, magnetism, and optical characteristics is strongly related to function. Such electronic ceramics are used by being incorporated into electronic devices such as smart phones and personal computers, or electric circuits such as substations and vehicles. In recent years, due to the development of manufacturing technology and the demand for miniaturization of parts, there are various shapes and sizes of electronic ceramics. In terms of porcelain, a chip shape with a certain size is recalled. However, electronic ceramics of various shapes are manufactured, either in an extremely thin film state or in the form of a single crystal.
In addition to the development of higher performance electronic ceramics, this group is also developing manufacturing technology for producing electronic ceramics. Through these, we aim to contribute to further progress such as information and communication technology with remarkable progress or technology for energy conservation.
