Malini et al prepared rubber ferrite composites containing nickel zinc ferrite (NZF) and examined the variation of tensile strength, elongation at... 

Makled et a/. reported the influence of co-precipitated hexagonal barium ferrite BaFei20ig phase on the cure characteristics and dynamic properties of NR-ferrite composites as a function of ferrite loading up to 2-20 phr (parts per hundred parts of rubber). The results showed that the scorch time decreased dramatically with increasing ferrite content until 160 phr BaF loading, this is because of the heat of mixing increases as the filler loading. 

Ferrites have been embedded in matrices under suitable preparation conditions for obtaining a performance required from the final composite. In ferrite and rubber composites, the magnetic properties depends on the fraction of ferrite in the matrix.

Thermal conductivity studies have been conducted on a wide range of filled polymers and composites, including carbon fibers [62-68], aluminum powder [65], nitride [66], magnetite, barite, talc, copper, strontium ferrite [67], glass fiber-filled polypropylene and manganese or iron-filled polyaniline, carbon nanotubes [68], and nickel-cobalt-zinc ferrite in natural rubber [70].
