Fine Ceramics, sometimes referred to as "advanced ceramics," are engineered materials that support the development of cutting-edge technology.

What are Fine Ceramics?

Term Coined by the Founder of Kyocera

High-precision ceramics create infinite value for society

Metal, organic materials, and ceramics are referred to as "The Big Three" materials. The English word for ceramics is derived from the Greek word "keramos", which means "burned clay."

The term ceramics originally referred almost exclusively to china. Today, we often refer to non-metallic, inorganic substances such as refractories, glass, and cements as ceramics. For this reason, ceramics are now regarded as "non-metallic, inorganic substances that are manufactured through a process of molding or shaping and exposure to high temperatures."

Among ceramics, porcelains are used in electronics and other high-tech industries, so they must meet highly precise specifications and demanding performance requirements. Today, they are called Fine Ceramics (also known as "advanced ceramics")* to distinguish them from conventional ceramics made from natural materials, such as clay and silica rock. Fine Ceramics are carefully engineered materials in which the chemical composition has been precisely adjusted using refined or synthesized raw powder, with a well-controlled method of forming and sintering.

Also, according to ISO** 20507 ("Fine ceramics – Vocabulary") and JIS*** R 1600, Fine Ceramics are "produced with precisely controlled chemical compositions, microstructures, configurations and production processes to fulfill intended functions, and are composed mainly of non-metallic, inorganic substances."

The term "Fine Ceramics" came into common use in the 1970s. Kyocera Corporation, founded as Kyoto Ceramic Co., Ltd., has primarily manufactured ceramics for the electronics industry since its inception in 1959. Founder Dr. Kazuo Inamori has maintained that "unlike conventional ceramics, Fine Ceramics possess high added-value in industrial applications. Their value should not be measured based on volume and they must be 'fine' both physically and structurally." He was therefore the first person to use the term "Fine Ceramics" in the contemporary sense.

The term "Fine Ceramics" is interchangeable with "advanced ceramics," "technical ceramics" and "engineered ceramics." Use varies by region and industry.
