Abstract

Synthetic monocrystalline diamond compositions having one or more monocrystalline diamond layers formed by chemical vapor deposition, the layers including one or more layers having an increased concentration of one or more impurities (such as boron and/or isotopes of carbon), as compared to other layers or comparable layers without such impurities. Such compositions provide an improved combination of properties, including color, strength, velocity of sound, electrical conductivity, and control of defects. A related method for preparing such a composition is also described., as well as a system for use in performing such a method, and articles incorporating such a composition.

Claims (20)

1. A diamond tool comprising:

a shaped diamond having alternating layers of single crystal diamond wherein adjacent layers have lattice mismatch such that the diamond is strengthened; and

a conductively doped single crystal diamond outer coating.

2. The diamond tool of claim 1 and frirther comprising a ground connection to the outer coating to reduce static electricity.

3. The diamond tool of claim 1 wherein the single crystal diamond outer coating is doped with boron.

4. The diamond tool of claim 1 wherein the diamond is in the shape of a surgical knife.

5. The diamond tool of claim 1 wherein selected layers are heavily doped with boron such that the diamond is generally blue in color.

6. The diamond tool of claim 1 wherein the diamond is in the shape of a microtome.

7. The diamond tool of claim 1 wherein the diamond is in the shape of a wire die.

8. The diamond tool of claim 1 wherein alternate layers are 12 C and 13 C diamond.

9. A diamond tool comprising:

a shaped diamond having at least one layer of single crystal diamond heavily doped to create a visible color to make the diamond more visible to a user; and

a single crystal diamond outer coating doped to make the outer coating conductive.

10. The diamond tool of claim 9 wherein the dopant of the shaped diamond is boron.

11. The diamond tool of claim 10 and further comprising a ground connection to the outer coating to reduce static electricity.

12. The diamond tool of claim 10 wherein the diamond is blue in color.

13. The diamond tool of claim 9 wherein the single crystal diamond is doped with boron.

14. The diamond tool of claim 9 wherein the diamond is in the shape of a surgical knife.

15. The diamond tool of claim 9 wherein the diamond is in the shape of a microtome.

16. The diamond tool of claim 9 wherein the diamond is in the shape of a wire die.
