ALUMINA CERAMIC – ONLY DIAMONDS ARE HARDER
The term ‘alumina ceramic’ refers to ceramic materials with an aluminium oxide (Al2O3) content above 80%. (Generally, only ceramics with a minimum Al2O3 content of 92% should be used for high-quality wear protection.)
Alumina ceramic is one of the hardest technical materials available and is currently the most important member of the group of oxide ceramic materials from a technical and economical perspective.
Densely sintered, it is characterized by:
- High strength and hardness
- High temperature and corrosion resistance
PRODUCT RANGE AND FORMATS
Thanks to the variety of possible shaping procedures, the product range is very diverse. Available are:
- Tiles in various sizes
- Very small tile platelets, vulcanised onto a support material or into rubber mats (generally square and hexagonal platelets).
- Straight pipe cylinders and pipe bends
- All kinds of special formpieces such as nozzles, reducers, inlets, pump casings, diffusers, etc., can be supplied according to customer drawings
AREAS OF APPLICATION
Owing to its substantial hardness and temperature resistance, alumina ceramic is used in areas subject to very extreme wear stresses, frequently in combination with high operating temperatures. Its availability with very low wall thickness allows for thin-wall wear protection linings that still offer a sufficiently long service life, especially in areas where weight or construction limitations do not allow the installation of a thicker wear protection lining.
The variety of products using this material permits the lining of any kind of plant component subject to extreme abrasion and high temperatures, e.g. separators, bunkers, diffusers, nozzles, hydro-cyclones, chain conveyors, reducers, mixers, pumps, trenches, piping, chutes, troughs, or cyclones.
