Claims
- 1. A densified ceramic and metal composition, consisting of:
- a ceramic, in an amount of at least 50 percent by volume of said composition, wherein said ceramic is selected from the group consisting of SiB.sub.4, AlB.sub.2, Al.sub.12 C.sub.2, Al.sub.4 BC, MgO, mullite, AlN, Si.sub.3 N.sub.4 or mixtures thereof; and
- a metal, wherein said metal is selected from the group consisting of Al, Mg, Ti, Fe, Ni, Co, Mn, Cu, Si, or their alloys, and said composition is substantially fully dense.
- 2. A densified ceramic and metal composition, consisting of:
- a silicon boride in an amount of about 50-80 percent by volume of said composition, wherein said silicon boride is selected from the group consisting of SiB.sub.4, SiB.sub.6, SiB.sub.14 or their mixtures; and
- at least one metal selected from the group consisting of Cu, Fe, Co, Si, Ni or their alloys.
- 3. The densified composition of claim 2 wherein the amount of silicon boride is about 50-75 volume percent of said composition.
- 4. The composition of claim 3 wherein said metal is Al and said composite is of a desired density, approaching 100 percent of theoretical density.
- 5. The composition of claim 3 wherein said metal is an aluminum alloy.
- 6. The composition of claim 3 wherein said metal is Cu and said composite is substantially 100 percent of theoretical density.
- 7. A densified ceramic and metal composition, consisting of:
- SiB.sub.6, in an amount of at least 50 percent by volume of said composition; and
- a metal, wherein said metal is selected from the group consisting of Mg, Ti, Fe, Ni, Co, Mn, Cu, Si, or their alloys, and said composition is substantially fully dense.
- 8. A densified ceramic and metal composition, consisting of:
- a silicon boride in an amount of about 50-80 percent by volume of said composition, wherein said silicon boride is a mixture of SiB.sub.4 and SiB.sub.6 ; and
- a metal selected from the group consisting of aluminum and aluminum alloys.
- 9. The densified composition of claim 3 wherein the metal is aluminum, said densified composition having a density of from about 95 to about 100 percent of theoretical density.
