Product Details
Zirconia is a very advanced industrial ceramic materials, it offers high strength, wear resistance, and flexibility far beyond those of most other technical ceramics. It surpasses most common ceramics with its distinctive strengths of “no brittleness”. The typical one is yttria stabilized zirconia (Y-TZP zirconia), it is the mostly used member of to PSZ zirconias group. It is composition of 94.7% ZrO2 + 5.2% Y2O3 (weight percentage) or 97.0 ZrO2 + 3.0% Y2O3 (mol percentage).
There are several grades of zirconia, and the most common of which are yttria partially stabilized zirconia (Y-PSZ) and magnesia partially stabilized zirconia (Mg-PSZ). Both of these materials offer excellent properties, suitable for piston and plungers use. Their unique resistance to crack propagation and high thermal expansion make it an excellent material for joining ceramics with metals such as pistons and plungers units.

Compared with alumina ceramics, Yttria stabilized zirconia (YSZ) pistons and plungers could withstand even higher temperature and get much better corrosion and wearing resistance. As an extremely refractory material, working temperature of zirconia parts could be as high as 1800℃ and being stable to most of corrosive chemicals as well. Its unique self-lubrication characteristic made it long life span and maintenance free in sealing assembly. While magnesium stabilized zirconia(Mg-PSZ) get a even better corrosion resistance in harsh chemical environments.
Due to the super high hardness and wearing resistance, zirconia pistons and plungers is not easy for further machining or grinding, however Fine-boon company has professional experiences and extensive knowledge, advanced CNC machines equipped with diamond cutting tools for its further machining process. All our machined zirconia pistons and plunger can achieve high precision and tight tolerance for further assembly purpose. We can design and make precision mould for its green body forming and get a scientific calculation for its shrinkage ratio during sintering in furnace, so its machining allowance is controlled as little as possible. This will save our machining time and cost significantly.
Shanghai Fine-boon company is internationally renowned as one of the world’s authorities in custom ceramic component design and engineering. Over the last 20 years of working with advanced ceramic materials, we have engineered and designed thousands of custom technical ceramic components to help our global customers utilize ceramics in new and innovative ways. What we can provide to you is not just our ceramic pistons and plungers, but also a comprehensive ceramic solution for your system upgrading in facilities, which traditional material can’t meet your growing demand for high quality. We offer unmatched flexibility with a variety of professional services to ensure our zirconia pistons and plungers delivered promptly and reach our customers satisfaction. We will be your trustworthy technical ceramic engineering and designing expert from now on.
