What is ceramics?

An advanced material from 10,000 years ago.

Ceramics are one of the three main categories of industrial materials, alongside metals and plastics.
The history of ceramics stretches back 10,000 years,
playing major rules in culture and everyday life since the dawn of human civilization.

The Diverse Functional Properties of Fine Ceramics

According to the Ceramic Society of Japan, ceramics are “non-metallic, inorganic solid materials produced through artificial processing.” Additionally, according to JIS R 1600:2011 (Glossary of Terms Related to Fine Ceramics), fine ceramics are defined as “primarily non-metallic, inorganic materials with new functions or properties, with carefully controlled chemical compositions, crystalline structures, microtextured organizations/grain boundaries, forms, and manufacturing processes.”

Main Types of Fine Ceramics

Scroll horizontally

Alumina Al2O3 Aluminum oxide. One of the most commonly used ceramic materials for fine ceramics.
Zirconia ZrO2 Zirconium oxide. The strongest and toughest fine ceramic material.
Aluminum Nitride AlN With its excellent thermal conductivity, this is often used as packaging material for semiconductor components and other applications requiring heat radiation.
Silicon Carbide SiC Does not naturally occur. An exceptional thermally resistant material: it maintains its strength even at high temperatures, and is light yet resists corrosion.
Silicon Nitride Si3N4 A material with outstanding toughness even at high temperatures and exceptional thermal shock resistance, and which is corrosion-resistant yet lightweight. Used as a material for engine components.
Forsterite 2Mg・SiO2 Features excellent high-temperature insulation properties, with low microwave loss. Used in components for electrical and electronic products.
Cordierite 2MgO・2Al2O3
Its particularly low thermal expansion gives this excellent thermal shock resistance. A porous, fireproof material.
Barium Titanate BaTiO3 With some of the highest electrical permittivity of any ceramic material, this is excellent at storing electrical charges, leading to its use in capacitors.
Lead Zirconate Titanate PZT Run an electric signal through this piezoelectric material to cause it to vibrate, or use its properties to convert vibrations into an electric signal.
Ferrite M2+O・Fe2O3 A magnetic ceramic material with high magnetic permeability, as well as significant electrical resistance and abrasion resistance.
Mullite 3Al2O3·2SiO2 This heat-resistant material has excellent creep resistance, as well as superb heat tolerance and thermal shock resistance.

The Possibilities of Ceramics

Ceramics offer a diverse variety of uses, both in products that are a crucial part of everyday life, and in solutions to resource, energy, and environmental issues. As time goes on, the roles they play are expected to only grow more important.
