Durable ceramics extended lifetime


The use of zirconia nanopowders made in DonIPE as starting material ensures high level of ceramics properties. Combination of chemical inertness, thermal resistance, improved mechanical properties, low corrosion rate and high degradation strength of zirconia ceramics opens wide range of its applications. Production of friction pairs is also possible due to low friction coefficient and low wear of oxide ceramics. Opposed to zirconia ceramics, silicon carbide one has high thermal conductivity and is a matchless material for use in thermal shock environment. It’s excellent thermal shock abilities along with improved strength due to the use of nanopowders make this ceramic an outstanding material for operation at elevated temperatures. Unique production technology provides the sintering of complex shaped ceramics for various applications and real life tests* show 20 to 50 times increase in life time over high-strength steel analogs at affordable price.
