Prepn process of tantalum-containing carbon-base composite material precursor

The preparation process of tantalum-containing carbon-base composite material precursor includes mixing coal tar pitch or petroleum asphalt of softening point of 60-80 deg.c and tantalum chloride in the mass ratio of 100 to 1-20 in inert atmosphere and water-less environment; and reaction at 260-420...

More Information
Summary:The preparation process of tantalum-containing carbon-base composite material precursor includes mixing coal tar pitch or petroleum asphalt of softening point of 60-80 deg.c and tantalum chloride in the mass ratio of 100 to 1-20 in inert atmosphere and water-less environment; and reaction at 260-420 deg.c and self pressurizing or 0.3-1.0 MPa pressure while mechanical stirring for 4-10 hr. The preparation process is simple and low in cost, and the tantalum-containing carbon-base composite material precursor may be used as the soaking agent, adhesive or self-sintering material for preparing high performance tantalum-containing carbon-base composite material.
