Description
Advanced ceramics refer to
materials, which exhibit superior mechanical and physical
properties. These include superior corrosion/oxidation resistance,
and thermal, electrical, optical or magnetic properties. Advanced
ceramics generally include structural ceramics, electronic
ceramics, ceramic coatings, and bio-ceramics.The varieties of
Advanced ceramics materials include:
Aluminum Oxide(Al2O3)
Aluminum Oxide (Al2O3) a is the most well-known and cost-effective
ceramic material. Due to a combination of good strength, a high
E-module and thermal shock resistance you can find it in
high-temperature applications such as protective tubes, as well
those where low friction is required i.e. slide bearings in pumps.
The good hardness and the excellent temperature durability (max.
operation temperature 1,**0°C) makes Aluminum Oxide a reliable
partner.
Zirconium Oxide(ZrO2)
Zirconium(di)oxide (ZrO2) is favoured in wide range of mechanical
and forming applications as it has the highest fracture toughness
of the oxide ceramic materials. It also possesses very good high
temperature properties and can be joined directly to steel due to
the compatible coefficients of expansion. Due to its excellent
biocompatibility, strength and translucency, zirconia is
increasingly used in the construction for zirconium oxide products
like crowns and bridges in dentistry.
Boron Nitride(BN)
Boron Nitride is a synthetic technical ceramic material, which is
available in powder, solid, aerosol and liquid forms. It has
out-standing thermal characteristics; high thermal conductivity and
excellent thermal shock resistance and is stable in inert and
reducing atmospheres up to ***0°C, and in oxidizing atmospheres to
**0°C. In its solid form, Boron Nitride can easily be machined to
close tolerances in virtually any shape. After machining, it is
ready for use without additional heat treating or firing
operations.
Machinable Glass Ceramic(MGC)
Machinable Glass Ceramic is used widely because of its special
property. The most important feture is its machinability. It can be
quickly, accurately and economically machined into high-precision
components using ordinary metalworking tools and does not require
any post-firing after machining has been completed. Moreover, it
has the same temperature resistance up to ***0℃. Its low thermal
conductivity is also one of valuable properties. The manufacturing
time and cost is reduced because the post-firing process has been
removed.
