Abstract

A polycrystalline super hard construction has a body of polycrystalline diamond material with a working surface, a first region substantially free of a solvent/catalysing material extending a depth from the working surface into the body of PCD material, and a second region remote from the working surface that includes solvent/catalysing material. The first and second regions are joined along a boundary. A chamfer extends between the working surface and a peripheral side surface of the body of PCD material. The distance from the midpoint of the chamfer to the boundary of the first and second regions along a plane substantially perpendicular to the plane in which the chamfer extends is at least X divided by two, where X is 0.8 times the thickness of the body of PCD material.

Abstract

A diamond powder comprising diamond particles having an average particle size of no more than 20 μm and a vacancy or impurity-vacancy point defect concentration of at least 1 ppm. At least 70% of the volume of diamond in the powder is formed from a single crystal growth sector. This leads to a substantially uniform concentration of vacancies or impurity-vacancy point defects in the diamond particles because the rate of impurity take-up during growth is heavily dependent on the growth sector, which in turn leads to a more uniform fluorescent response. There is also described a method for making such a powder.

Abstract

A cutting bit assembly for a mining machine includes a holder having a first surface, a second surface, and a bore extending therebetween, and a bit having a first end and a second end. The bit further includes a tip, a shank, and a shoulder positioned between the tip and the shank. The shank is positioned in the bore of the holder and defines a shank axis. The shoulder engages the first surface of the holder. The shank includes a projection adjacent the second end. The cutting bit assembly also includes a retainer having a groove and a resilient member. The groove engages a portion of the projection. The resilient portion engages the second surface of the holder and biases the retainer along the shank axis and away from the holder.

CAPSULE ASSEMBLIES FOR ULTRA-HIGH PRESSURE PRESSES AND METHODS FOR USING THEM

Abstract

A capsule assembly for an ultra-high pressure furnace, comprising a containment tube having an interior side surface and defining a central longitudinal axis; a chamber suitable for accommodating a reaction assembly, a proximate and a distal end heater assembly, and a side heater assembly. When assembled, the chamber is contained within the containment tube and arranged longitudinally between the proximate and distal end heater assemblies. The side heater assembly is disposed adjacent the interior side surface and electrically connects the end heater assemblies with each other. Each end heater assembly has a respective peripheral side disposed adjacent the interior side surface. Heat is produced in the chamber in response to an electric current flowing through the end and side heater assemblies. At least a proximate side heater barrier spaces apart the side heater assembly from at least the proximate end heater assembly, adjacent its peripheral side, operative to prevent a portion of the side heater assembly from intruding between the peripheral side of the proximate end heater assembly and the containment tube and short-circuiting at least part of the proximate end heater assembly, when the end heater assemblies move towards each other in response to a force applied by the ultra-high pressure furnace onto the capsule assembly along the central longitudinal axis.
