Ceramics |
 |
Alumina ceramics are the most widely used materials in the variety of fine ceramics, which after being subject to a sintering process, feature the same crystal structure (  ) as sapphire and ruby. These materials are used in a wide range of industrial fields due to their superb material characteristics such as high electrical insulation, high mechanical strength, and high wear- and chemical-resistance.

| Silicon
Nitride |
|
Silicon nitride (  ) exceeds many other ceramic materials in thermal shock-resistance. It does not deteriorate at high temperatures; therefore, it is ideal for use in components for automotive engines and gas turbines — including turbocharger rotors, glow plugs for diesel engines, and hot plugs. Further applications of this material are anticipated in a wide range of fields.

| Silicon
Carbide |
|
Silicon carbide maintains its high mechanical strength up to temperatures as high as 1,400 .
It is also typically used in parts for mechanical seal rings and pumps due to its high resistance to chemical corrosion compared to other ceramic materials.

| Zirconia
Ceramics |
|
Compared to other fine ceramics, Zirconia ceramics have high mechanical strength and toughness at room temperature. Due to these characteristics, Zirconia was the first material utilized to manufacture fine ceramic scissors and knives. Its excellent surface smoothness has also allowed this material to be used in parts for pump applications.
