  • CVD process for making a hollow diamond tube
    Patent number: 5798143
    Abstract: A method for producing hollow diamond tubes by diamond growth using chemical vapor deposition (CVD) techniques. Suitable substrate material, such as tungsten, molybdenum, copper or silicon, typically in the form of wire, having diamond nucleation sites is formed into a helix. The helix is then placed, or moved through, a CVD chamber for deposition of diamond on the helix. Suitable pitch and diameter of helix results in deposition diamond on the helix until such time as the growth surfaces of the diamond fuse to form a hollow diamond tube.
