Self-propagating high-temperature synthesis (SHS), refers to a technology for the production of useful materials (mainly composite powders) that uses combustion processes. The solid combustion process results in the release of more heat which is needed to rebond the elements of the system and it is this extra amount of heat that is used to self-sustain the combustion process and its development. This process is known as self-propagating high temperature synthesis.
This paper presents the study of the magnetic properties of the products obtained by this method in comparison with other methods which use nickel-zinc ferrites. The latter are widely used in radio devices, antennas and transformer cores, as well as in high-frequency filters where the current loss is significant.
