Zirconia Ceramic Plungermerits
Zirconia ceramic plungers are high-performance precision ceramic parts with a wide range of applications. Compared with metal plungers and ordinary plastic plungers, zirconia ceramic plungers have obvious advantages in terms of abrasion and corrosion resistance, sealing stability and service life, and are becoming increasingly popular in high-end industrial equipment. The thermal stability of zirconia ceramics is also outstanding, and can maintain dimensional stability in environments with large temperature variations, without seal failure due to thermal expansion, which is particularly important for high-temperature fluid transportation and continuous production equipment.
Description
Advantages of Zirconia Ceramic Plungers
The biggest advantage of zirconia ceramic plunger is firstly embodied in the strong wear-resistant performance, with very high hardness, high surface finish after precision grinding and polishing, very low friction loss in long-term reciprocating motion, able to maintain the stability of the outer diameter size over a long period of time, and is not easy to produce wear and tear of the problem of thinning, so as to ensure the sealing accuracy between the plunger and the pump chamber. Excellent toughness and impact resistance. Zirconia is a material with outstanding toughness, less brittle than aluminum oxide, especially suitable for high-speed reciprocating motion, frequent start-stop and pressure fluctuations in a large working environment, can effectively improve the reliability of equipment operation.
- Wear-resistant, not easy to deform for long-term use
- High toughness and impact resistance
- Acid and alkali corrosion resistance, adapt to complex media
- Dimensional stability for more accurate measurement
- Long life and reduced maintenance costs

Basic properties of magnesium-stabilized zirconia ceramics
Magnesium-stabilized zirconia ceramics use magnesium oxide (MgO) as a stabilizer for zirconia, and the crystal structure is cubic lattice after molding, which is more stable. Magnesia-zirconia has better resistance to high temperature and humidity because it is not affected by phase migration. Magnesia-zirconia maintains its strength even in humid, high-temperature environments where the mechanical properties of yttrium oxide partially stabilized zirconia begin to deteriorate.
