Abstract: The present invention consists in obtaining, with the capsule described, a vertical gradient favorable for diamond growth that prevails over any radial gradient by means of heating discs placed at the ends of the heating area, which implies a considerable control over the growth conditions. More specifically, in regard to the rate of growth, it allows for a better control of the quality of large crystals. Another important novelty is to use a source of carbon with a special design formed by cylindrical and conical hollows (graphite, amorphous carbon, diamond or other) with a solvent metal with a number of gases that are introduced in the capsule.
Also, a nitrogen scavenger is used to avoid the formation of nitrides, carbides and oxides that are harmful for the growth and that as a significant novelty is placed outside the reaction area.

Abstract: A composite material consists of a plurality of cores dispersed in a matrix. The cores are formed of ultra-hard material, or the components for making an ultra-hard material. The matrix is formed of the components for making an ultra-hard material of a grade different to that of the cores, and a suitable binder. The ultra-hard material is polycrystalline in nature and is typically PCD or PcBN. The cores are typically provided as granules coated with the components for making an ultra-hard material and the binder. The composite material typically takes on a honeycomb structure of an ultra-hard material and cores within the pores of the honeycomb structure bonded to the honeycomb structure. The pores of the honeycomb structure may be ordered or random.

Abstract: An electric pulsed power vacuum press assembly (10) is provided for delivering high-power, short-duration electrical pulses to a selected sample (11) which is simultaneously subjected to mechanical compression. A hydraulic press (14) provides mechanical compressive force to a press insert member (12) containing the sample (11). Pulsed electrical power is delivered by a power supply assembly (16) and vacuum by a vacuum assembly (18). The electrical pulsed power is delivered through the sample (11) along an electrical pathway (49) characterized by very low inductance and resistance. The preferred electrical pathway (49) exclusively utilizes parallel plate conductor portions and coaxial line portions. The assembly (10) is adapted to provide very high short duration temperatures and is used for purposes such as synthetic diamond production.

Abstract: Broadly, the present invention is directed to a method for achieving high pressure wherein a sample is placed between a pair of diamond anvils and the anvils compressed. The improvement comprises forming the anvils from one or more of isotopically-pure ¹²C or ¹³C diamond. Isotopically-pure ¹³C diamond is preferred as it has the highest atomic or bond density parameter of any known material and, therefore, should have the highest hardness also. Isotopically-enriched diamond ¹³C diamond should find utility as an anvil with higher ¹³C contents increasing the hardness of the anvil product. By utilizing isotopically pure diamond anvils, less breakage at current pressures should be realized concomitant with the ability to achieve yet higher pressures.

Abstract translation: 概括地说，本发明涉及一种实现高压的方法，其中将样品置于一对金刚石砧和压砧之间。 该改进包括从同位素纯的1 C或3 C 3金刚石中的一种或多种形成砧座。 同位素纯度<1> 3 C金刚石是优选的，因为它具有任何已知材料的最高原子或键密度参数，因此也应具有最高的硬度。 同位素富集的金刚石<1> 3 C金刚石应用作砧座，具有较高的<1> 3 C含量，从而提高砧座产品的硬度。 通过利用同位素纯金刚石砧座，应当实现当前压力下的破裂，同时实现更高压力的能力。

Abstract: Systems and methods are directed to selecting unpolished regular-polygonal diamonds; selecting diamond powder based on size, profile and hardness to use as acceleration media; and polishing the regular-polygonal diamonds by accelerating at least the diamond powder using a plurality of spray patterns determined as a function of the respective hardnesses of the diamond powder and the unpolished regular-polygonal diamond, the spray patterns directed at the unpolished regular-polygonal diamonds. The method further includes accelerating the regular-polygonal diamonds and the diamond powder to create the spray patterns; directing the spray patterns so that they overlap causing the diamond powder to polish the regular polygonal diamonds; separating the regular-polygonal diamond from the diamond powder; and repeating the steps of accelerating the regular polygonal diamonds and the diamond powder and the separating until the regular-polygonal diamond is polished.
