Organo-silicate insulating binder system for metal powders allowing thermal annealing to reduce magnetic losses

We have developed an effective thermally stable binder/coating system based on organo-silicate materials, which can be used in combination with metallic powders to provide annealable dielectromagnetic composites - A key deliverable for the project. These systems allow thermal annealing to temperatures between 450 and 600C, the latter being a significant improvement on the best currently available systems.

This system is one of three variants that we have developed, and offers intermediate cost and performance between the three (i.e. neither the lowest cost nor the highest performance). Of the three systems developed it was thus considered to be less commercially attractive and was therefore chosen instead as a model system through which the properties and behaviour of dielectromagnetics in general could be scientifically explained and discussed in the open literature. This is considered to be a vital step in achieving the necessary confidence to allow designers of electrical machines to specify and use dielectromagnetics of all types in their products. This crucial dissemination route will involve a number of technical and trade journal and international conference papers.
