Zirconia/Black zirconia/Blue Zirconia/ Hipped zirconia ceramics

Zirconia

Zirconia (ZrO2) is a hard and tough solid solution combined with Zirconia and a small amount of Yttrium.

With its good wear resistance, electric insulation, and chemical resistance, Zirconia is commonly used as wear-resistant components and machine parts.

The thermal conductivity of the zirconia is very low (3w/m・K). Therefore, it can also be applied as a heat insulator.

N-650 Zirconia engineering ceramics

Zirconia（ZrO2）

Zirconia has excellent hardness, toughness, wear resistance, good electric insulation, and chemical resistance.

Zirconia is a strong, durable, and sturdy material; the material is commonly used as wear-resistant components and machine parts.

The thermal conductivity of the zirconia material is very low (3w/m・K). Therefore, it is also can be applied as a heat insulator.

N-650B Black Zirconia engineering ceramics

Nishimura advanced ceramics produce black colored zirconia ceramics.

Commonly used as machine parts, optical parts, spindles and looms parts, and measuring equipment.

It is also used for ornaments.

N-660B Blue Zirconia engineering ceramics

Nishimura advanced ceramics produce blue zirconia ceramics.

It is commonly used as machine parts, optical parts, spindles and looms parts, and measuring equipment.

It is also used for ornaments.

N-650H Hipped Zirconia engineering ceramics

Nishimura advanced ceramics produce hipped zirconia by the HIP processing.

HIP is the name of the processing. Nishimura advanced ceramics take this process with burnt zirconia ceramics. The HIP process gives heat and pressure.

HIP zirconia has better strength, wear resistant and antifriction than a normal zirconia material.

The material is specially suitable for component like a cutter or punching tool.

Highest Fracture toughness Zirconia N-632

This is a Zirconia that has fracture toughness 8.9MPa・m1/2　Zirconia（Approx.1.5 times higher fracture toughness than usual Zirconia）
It can be used as a case for a digital device, cutting tool, positioning pin, measuring probe, and more.
