We prepared carbonyl iron particles by method of heating the solution of Fe(CO) 5/DFM stage by stage.

Carbonyl iron particles and iron-epoxy resin composite particles, which both MRS and microwave absorber are based on, were prepared by method of dropping Fe(CO)5 to DMF in constant temperatures and of heating the solution of Fe(CO)5/DMF stage by stage, combining in situ composite technique.

Study on the surface modification of carbonyl iron;

Study on ferrite/carbonyl iron composite absorber;

TGA(mass reduction) curves showed the high magnetic content of the porous composites and XRD spectra showed that carbonyl iron particles in porous composite micro-spheres were not changed but remain the magnet of its own.

Research on microwave absorbing properties of polychloroprene matrices containing modified carbonyl iron powder;

Property and preparation of carbonyl iron powder/polymethacrylate/poly-aniline composite absorbents;

Effects of various factors including coupling agent,fumed silica and carbonyl iron powder(CIP) amount on mechanical properties of room temperature vulcanized(RTV) silicone sealant by use of CIP and PDMS as its absorbent and matrix are studied.

; We have found from experimental data that, in the iron pentacarbonyl molecule, the length of FeC bond in axial is shorter than that in planar, but the bond is weaker; the bond distances of CO of both planar and axial are equal, while the bond strengths are different.

A novel magnetorheological fluid was prepared with nanometer lithium magnesium silicate,carbonyl iron particle,silicon oil and so on.

The magnetic properties of carbonyl iron particles were characterized by VSM;the apparent viscosities and the magnetic field-induced shear stresses of the magnetorheological fluids above were investigated by an advanced rheometric expansion system;the properties of MR damper were tested by an electro-hydralic servocontrol testing system.
