High-temperature application - Import export

Extreme-pressure grease for high temperature applications and heavy loads.

Non-flammable, long life white grease designed for high temperature textile applications.

Zirconia grades are various. They differentiate from each other by the nature of the stabilising agent which is used. In its pure form, zirconia is not stable. Magnesia-partially-stabilised zirconia (MgO-PSZ) and yttria-partially stabilised zirconia (Y-TZP) in particular offer an outstanding resistance to mechanical shocks as well as to flexural load, because of their high fracture toughness and relative “ elasticity ”. These two zirconias are advanced ceramics of choice for severe mechanical applications. Other grades in fully stabilised composition exist and are mostly used for high-temperature applications. Selection of materials Microcertec offers those two types of zirconias that are mostly requested on the market, in pressed and extruded grades : magnesia-partially-stabilised zirconia (MgO-PSZ) yttria-partially-stabilised zirconia (Y-TZP) Properties MgO-PSZ and Y-TZP zirconias have the following features : high density high flexural strength (> 500 MPa for Mgo-PSZ and >...

Various methods of assembly exist to bind ceramic to metal. When it comes to make an assembly that can resist to mechanical stresses and/or high temperatures, be vacuum leak tight and withstand corrosive environment, high temperature, braze sealing is essential. Applications Ceramic-to-metal brazed assemblies are particularly suited for use in airborne electronics for the aerospace, defense devices, medical and analytical instruments,high-energy physics, high vacuum equipment, the nuclear industry... We offer customized ceramic to metal brazed assemblies such as for instance : high-voltage feedthroughs for the mass spectrometry, hermetic packages for airborne electronics or sensors for the oil industry, high-voltage hermetic connectors for the nuclear industry, high-voltage insulators for electron tubes.
