High wear resistance | Impact resistant | Recommended for wear parts ZTA's our core activity ZTA (Zirconia Toughened Alumina) is an alumina and zirconia composite material mix: this helps to get the properties from both material in a single ceramic powder. The ZTA then inherits of high temperature and wear resistance from the alumina but also the impact resistance from zirconia. The different alumina-zirconia ratios offered by Nanoe enables the client to pick a product best suited to his needs. Thanks to our unique know-how on powder synthesis, the parts made with our ZTA have a very fine microstructure with a high homogeneity, resulting in higher mechanical properties. ZTA12 ZTA12 is a 88% Alumina and 12% Yttriated zirconia mix. This composition, the result of extensive research carried out by our R&D department, ensures an optimal level of hardness, electrical resistivity and hydrothermal ageing resistance. Like for the ZTA25 powder, our ZTA12 powder has a high wear resistance, we can also offer chrome-doped ZTA12 to have an even better wear resistance. Applications ZTA12 makes it possible to make wear parts with a longer service life and therefore lower maintenance and replacement costs. It is used in various industries: semiconductors, wood cutting, etc. Semiconductor: In the semiconductor sector, ZTA makes it possible to make parts with a longer service life … Wear parts and tools: For the manufacture of wear parts such as wire guides or cutting tools, ZTA makes tools that are both abrasion and impact resistant… A product adapted to your process In order to best meet your needs, Nanoe delivers ZTA12 in the form that best fits your process. We are thus able to supply our materials in the form of ready-to-press granules, redispersible powders or feedstocks for ceramic injection. Nanoe is able to adapt the ZTA to your request so that it meets your specific constraints, for example by adapting the alumina/zirconia ratio or by adding dopants.

Thermal barrier Engines with higher efficiency are synonymous with engines rising to higher temperatures, this leads to undeniable technical challenges.The protection of hot parts of aircraft engines is the sine qua non for their proper operation.The yttria-sabilized zirconia, used as a coating, is ideal for insulating the hot turbine floors.Its low thermal conductivity, structural stability at temperatures up to 1600 degrees celsius and corrosion resistance to the combustion gases make it an ideal material. We offer powders for... high-purity yttria-stabilized Zirconia for the insulation of hot engine parts.

Ceramic Matrix Composite (CMC) The CMC is one of the future solutions to meet the challenges of aeronautics, and will soon replace metal parts such as engine backends and engine mast thermal protections in future aircraft generations. Made of a ceramic fiber impregnated with alumina, they are very light and more tenacious than traditional ceramics.Thanks to our unique know-how in powder synthesis, the AL100 alumina from Nanoe used for CMC is extremely thin and thus allows to obtain a final part resistant to thermal shock and fractures. We offer powders for CMC (ceramic matrix composites) that are both lightweight and resistant to high temperatures

Nanoe offers coloured zirconia and chrome alumina, also known as polycrystalline rubies, to meet the needs of the luxury industry. Our powders are very thin, they ensure optimal mechanical properties and a very beautiful appearance. Watch bearing For watchmaking stones, our chrome alumina is a material of choice. Our powders are very thin, they allow to produce dense bearings and have a very low friction coefficient. Thus, by making the movement of the needles smoother, the mechanisms consume less energy and gains in autonomy.
