08 Technical Ceramics
Heat-conducting technical ceramics ICT-TCC-ALO-96 and 99 (oxide ceramic-alumina) and ICT-TCC-ALN-200 (aluminium nitride-ceramics). The excellent thermal properties-combined with mechanical stability and high electrical insulation-are the driving force for the use of ceramic materials wherever an improved thermal conductivity is required.

PRODUCT DESCRIPTION
Ceramic insulating washers consist of aluminium oxide or aluminium nitride.
The ALO-96 and -99, made from aluminium oxide (Al2O3) is probably the best-known of these oxide ceramic materials.
In cooperation with our renowned German and Japanese suppliers, we are able to offer our clients a large variety of material types with different properties and different degrees of purity which are achieved through a precisely defined process. We typically provide ceramic washers between 0.5 and 2mm in thickness. Other gauges (3.0 to >5 mm or customized) are available only upon specific request.
Aluminium nitride ceramics is the ″cool″ high-performance solution, ideal for cutting-edge electronic performance. Maximum efficiency combined with high assembly density means that electronic components become increasingly hot. In this context, once again, the application dictates the most suitable T.I.M. to ensure efficient dissipation of waste heat for the protection of the component.
This is where ICT SUEDWERK comes into play: in collaboration with our renowned suppliers of aluminium nitride (ALN) ceramics we provide the ICT-TCC-ALN-200 product series which boasts outstanding insulating properties and extraordinary thermal conductivity (150 – 180 W/mK) that make it perfect for high-performance application in power electronics. ALN ceramics are also generally available in thicknesses between 0.5 and 2 mm; other gauges are available upon request. However, due to the current global material shortage, long delivery periods must be expected.
