Influences of surfactant on structure and performance of carbon foam;

A carbon foam matrix was prepared from aromatic resin(AR) pitch in a autoclave and then was carbonized at 1 050 ℃ and graphitized at 2 500 ℃ to form carbon foam.

Effect of template pretreatment on structure of carbon foams;

Carbon foam produced from fluid catalytic cracking slurry at atmospheric pressure;

Carbon foams were prepared from coal tar pitch, petroleum mesophase pitch, and AR pitch.

The effect of Si addition in carbon foam on the microstructures and properties of porous SiC ceramics was studied.

These applications include that pitch-based carbon foam is used as heat management material,silicon carbide foam is used as space mirror and micro turbine engine material,multifunctional coal-based carbon foam is used as radar absorption,electromagnetic shielding,structural assembly,and composite tooling.

Two carbon foams with different bulk density,marked as CF-1 and CF-2 were prepared from AR mesophase pitch by self-foaming method at 450℃under different foaming pressures,0.

Based on the mesophase-pitch-derived carbon foams,this article introduces the history and development of carbon foams,briefly reviews their preparation methods such as foaming by foaming agent method,foaming by template method,self-foaming of mesophase pitch method,size-restriction foaming method and so on,summarizes their performances and potential applications,and m.

Employing sealed dissolved sample, miniature air-chamber electrode and carbon charged foam plastics for separation and enrichment of gold, this paper developed chemical spectrometry to determine super-trace gold in chemical exploration sample achieving great success.
