摘要 |
The present invention comprises an improved method of consolidating particulate materials or combinations of such materials into shaped products of very low porosity. High compac- tion pressures are applied at temperatures in the range of sintering temperature of the materials being consolidated to achieve essentially complete densification at extremely rapid processing rates. Electrothermal heating is utilized to accomplish these results. Difficult materials such as silicon carbide, boron carbide and other very high melting point materials may be densified by these techni- ques.
