ZrO2

Zirconia

Zirconia, mainly consisting of ZrO2, has the high est mechanical strength and

fracture toughness at room temperature of all major fine ceramics. It is used to

make cutting blades, scissors and knives. It is also us ed for pump parts due to its

superior surface smoothness.

Features

Zirconia has excellent mechanical pr operties, with higher  strength and fracture

toughness than alumina.

It is also used in milling machines, sliding parts and cutting blades.

Zirconia exhibits great heat insulation, as its thermal conductivity is less than 1/10 that of 

other ceramics.

Configuration

Dimensional precision achieved by machining

When dimensional precision is required for machined ceramics , Kyocera is capable of achieving the tolerances as shown in

the table below. If greater tolerances are required, please consult us .

■MACHINING DIMENSIONAL PRECISION(Data are in mm unless othe rwise specified)

1.Ground ceramic blocks and plates

2.Round and Square Bars

■PRECISION MACHINED PRODUCTS

Ultra-precision is poss ible with Kyocera's unique techniques.

Precision m achining is affected by shape and m aterial.

Some practical examples are sho wn in the table below.
