Electrically conductive, flame retardant material and method of making same as well as method of use in an electromagnetic interference shielding material. The electrically conductive, flame retardant material comprises alumina trihydrate material treated to form an aluminum phosphate surface and an electrically conductive layer disposed thereover. In the form of particles, the electrically conductive, flame retardant material may be dispersed throughout a polymeric material to provide a flame retardant EMI shielding material. Such materials may be used as, for example, gaskets, caulking compounds, coatings and adhesives.
