Method of Obtaining Contact Composition.

摘要

Methods of obtaining contact composition on basis of epoxy resin and ferromagnetic metallic filler are noted for hardening metal-filled epoxy composition in magnetic field. However, the obtained contact composition does not make it possible to carry out a stable electrical contact at low temperatures (for example at temperatures of liquid nitrogen -196 C), since in this case the considerable loss of electrical conductivity occurs. Electrical contact, stable at low temperatures, succeeds in obtaining, using as electrically conducting filler dispersed silver. However, in this case cannot be carried out multipoint electrical contact, since silver is nonferromagnetic, and consequently, will not be structured in the magnetic field.
