    Abstract: Reaction vessel construction is described for suppressing spontaneous diamond nucleation and simultaneously reducing the flaw content in the main body of diamond grown from diamond seed material by the process broadly disclosed in U.S. Pat. No. 3,297,407 to Wentorf, Jr.In the reaction vessel construction the body of catalyst-solvent metal is formed with at least one small tip projecting from the underside thereof. A single diamond seed is placed in contact with this (or each) tip. The underside of the plug of catalyst-solvent metal is in contact with a nucleation-suppressing disc, or layer, of a material different from the catalyst-solvent and selected from a specific group of materials. In each case the tip of catalyst-solvent metal projects through a hole in the disc or layer to make contact with the diamond seed material.

    Abstract: Disclosed is an improved process for preparing a composite compact wherein a mass of abrasive crystals, a mass of metal carbide, and a bonding medium are subjected to a high-temperature/high pressure process for providing a composite compact. The sintered carbide mass supports the mass of abrasive crystals and bonding or catalyst metal, and the abrasive crystal grains are directly bonded to adjacent crystal grains in the mass thereof. Such improved process comprises disposing the mass of abrasive crystals in layers wherein the coarsest layer is closest to the carbide mass and is composed of crystals having a largest dimension of between about 75 and 500 microns and the finest layer is disposed farthest away in the carbide mass and is composed of crystals having a largest dimension of less than 10 microns. The abrasive crystals are selected from the group consisting of diamond and cubic boron nitride and preferably are diamond; the metal carbide preferably is tungsten carbide; and the bonding metal preferably is cobalt. The resulting improved composite compact also is disclosed.

    Abstract: In one embodiment, a compact for tools, such as cutting, drilling and shaping tools, consists essentially of self-bonded abrasive particles. The bonded particles define a substantially continuous interconnected network of pores, dispersed throughout the compact. The method for making such a compact comprises the steps of bonding a mass of abrasive particles, aided by a sintering aid material, under high temperatures and pressures (HP/HT) to form an abrasive body comprised of said particles in a self-bonded form and said material infiltrated throughout the body. The body is then treated to remove substantially all infiltrated material, thereby to produce a compact consisting essentially of the self-bonded abrasive particles. In another embodiment, a composite compact which is made in a similar manner to the first embodiment consists essentially of a layer of self-bonded abrasive particle and a substrate layer (preferably of cemented carbide) bonded to the abrasive particle layer.

    Abstract: A piston type system for forming industrial diamonds is provided with a pressure vessel which includes a tungsten carbide member having a central opening which has a tapered mouth at one end, and which is lined with a salt bushing. A charge including invar and graphite to be converted to diamond is inserted within the pressure chamber inside the salt bushing. An end load plate has a central opening of substantially the same diameter as the opening in the salt bushing and has a tapered flange which fits into the tapered mouth in the tungsten carbide pressure vessel. A tungsten carbide piston which has a diameter about 0.003 inch less than the diameter of the opening in the end plate, and which has a lead gasket between its surface and that of the opening in the end plate, is forced through the end plate and applies high pressure at high temperatures to the charge, thereby converting the graphite to diamond after the passage of a suitable period of time. The tungsten carbide piston need only have the diameter of the inner diameter of the salt bushing, instead of a diameter equal to the full I.D. of the tungsten carbide pressure vessel.
