Patent number: 6110594Abstract: Porous and non-porous compositions include diamond particles, non-diamond particles, or mixtures of particles consolidated with polycrystalline diamond. The composite compositions of the present invention may be formed by a process which includes the steps of preforming the particles into a preform having a desired shape, and consolidating the preform with polycrystalline diamond. The polycrystalline diamond is preferably formed using CVD techniques including application of sufficient microwave energy to maintain the preform at a temperature of between about 670.degree. and 850.degree. C. The preform may be rotated during a portion of the deposition process.Type: GrantFiled: October 20, 1994Date of Patent: August 29, 2000Assignee: Advamced Refractory Technologies, Inc.Inventor: John M.

Patent number: 5902563Abstract: Processes are disclosed for performing non-microwave, non-arcjet plasma-assisted chemical vapor deposition of diamond in which substantially no particles impact the growing diamond surface with energies sufficient to prevent the growth of diamond. The energies of the particles are limited by selecting frequency, pressure, magnetic fields, electrical bias, or a combination thereof to the deposition region of the chamber. Diamond materials formed by these processes are also disclosed.Type: GrantFiled: October 30, 1997Date of Patent: May 11, 1999Assignee: Pl-LimitedInventor: John M. Pinneo

Patent number: 5852341Abstract: An ultrasmooth diamond film has a thickness greater than about ten microns and an average grain size less than about 0.5 micron. The ultrasmooth diamond film of the present invention is grown using ordinary microwave plasma CVD methods, with a metal vapor source included in the reactor to produce vapor during the growth of the film. The metal vapor source may be chosen from the first row transition elements, chromium, iron, cobalt, and nickel, or from the lanthanides praseodymium, europium, or erbium. Any metal capable of existing in the vapor phase in the presence of the hydrogen plasma, will cause formation of the ultrasmooth film of the present invention.Type: GrantFiled: November 4, 1996Date of Patent: December 22, 1998Assignee: CrystallumeInventors: William Phillips, John M. Pinneo

Patent number: 5607723Abstract: A continuous thin diamond film having a thickness of less than about 2 microns has a low leakage. The thin diamond film may be supported on a supporting grid and may be incorporated into an X-ray window. The film may be formed in a DC assisted CVD process where in a first phase a relatively high concentration of a carbonaceous gas is introduced into the reactor and in a second phase the concentration of the carbonaceous gas is reduced to a lower value.Type: GrantFiled: May 5, 1994Date of Patent: March 4, 1997Assignee: CrystallumeInventors: Linda S.
