Product Description

high toughness zirconia ceramic plunger

 zirconia ceramic plunger,zirconium piston, zirconia ceramic piston

1.high hardness

2.high mechanical strength

3.good corrosion resistance

 zirconia ceramic.

High hardness. Mohs hardness is 6.5, so that can make cold forming tools, plastic mold, drawing die mold, cutting tools and so on.

Mechanical strength high, good toughness. Normal temperature the flexural strength can reach ***0Mpa. ***0 centigrade can reach ***0Mpa. Our company production of excellent toughness of zirconia ceramics normal temperature bending strength can reach ***0Mpa, so it can be used to make the engine components, such as push rod, connecting rod, bearing, cylinder liner, piston hat, the spark plug and so on.

Zirconia ceramics also has semiconductor performance. Zirconia ceramics in high temperature with semiconductor performance. Pure zirconia ceramics are good insulators, specific resistance can reach ***3 ohm·cm. join the stabilizer, can keep zirconia ceramics crystal of electric neutrality. Because of ZrO2 have such characteristics. So it often used to manufacture high temperature heating elements. ZrO2 heating elements can use in the air. The highest temperature can be achieved ***0~***0 centigrade.

The resistivity of zirconia ceramics
