FRIATEC has developed an Alumina ceramic for application in the radar and microwave technic. Because of its excellent electrical and mechanical properties the material can be used as high-grade microwave screens and high frequency filters. Products made from AL23 hf are applied with great success as microwave windows and antennas in radar-measuring-systems and for applications with special requirements to compressive and temperature stability.
Other possible applications for AL23 hf are components for isolators and supports in the telecommunication industry e.g. communication antennas, amplifiers, high frequency filters and electronic equipment for antenna systems. Examples for further applications are: systems for acceleration of pharmaceutical production processes, microwave heating equipment systems, sensors and analytical instruments.
The material FRIALIT®-DEGUSSIT® AL 23 hf offers extraordinary qualities:
- AL 23 hf has a high optical fraction value against other materials like glass or plastics. Because of that the microwaves can be focused and better controled. The components can be made of small size and therefore can very easily be integrated in smaller units.
- AL 23 hf offers – due to its high dielectric constant and low dielectric loss factor and contrary to many other materials – the possibility to realise microwave resonators with high-grade quality and temperature stability in manageable component sizes.
- AL 23 hf is temperature (up to 1,950°C) and wear resistant, has a very high form stability and, with 5.7ppm / K (20 – 100°C), a low thermal expansion.
- AL 23 hf has a FDA permit (Food & Drug Administration) and is therefore qualified and ideally suited to application involved in the food and pharmaceutical processing industry.
In addition to AL 23 hf FRIATEC AG produces and supplies SiO2-glass in various qualities for hybride constructions.
