Abstract:
Ultra fine nickel ferrite have been synthesized
by the sol-gel method. By heat treating different portions
of the prepared powder separately at different
temperatures, nano-sized particles of nickel ferrite with
varying particle sizes were obtained. These powders were
characterised by the X-ray diffraction and then incorporated
in the nitrile rubber matrix according to a specific
recipe for various loadings. The cure characteristics and
the mechanical properties of these rubber ferrite composites
(RFCs) were evaluated. The effect of loading and the
grain size of the filler on the cure characteristics and tensile
properties were also evaluated. It is found that the
grain size and porosity of the filler plays a vital role in
determining the mechanical properties of the RFCs
