Reliable joining of new materials often requires the use of adhesive bonding technology. Against this background, ad-hesive engineers may be interested to know that the ceramic manufacturer CeramTec has now succeeded in producing transparent ceramics on a series-production scale. The new material is called Perlucor and was presented for the first time at the Hannover Fair.
Perlucor is a highly pure material with a number of extraordinary mechanical, chemical, thermal and optical properties. With a high transparency of more than 80 % — which is equivalent to a relative transparency of over 90 % — the material opens up new fields of application wherever glass reaches its limits. In addition to its high transparency, Perlucor also has three to four times the hardness and strength of conventional glass. This makes it well suited for use in extreme wear conditions, for example in mechanical, plant or equipment engineering. The developers also see application possibilities in the field of medical engineering and in the areas of optical applications, architecture, jewellery and design.
Thermal and chemical stability
The new material has higher thermal stability than glass (by a factor of three). This makes it suitable for use at temperatures of up to 1,600 degrees Celsius. For example, the transparent ceramic can be used as an inspection window in high-temperature furnaces. Due to its purity, Perlucor also features extraordinarily high chemical stability, which means that it can also be used with highly concentrated acids and lyes.
