| titleOfInvention | Method for producing pellets of sintered material such as boron carbide pellets |
| abstract | The present invention comprises the following successive steps: a) forming a calibrated preform using a first uniaxial pressing of an equal mass portion of a material in powder form, said first step comprising: Forming a preform, wherein the pressing process is carried out to a first threshold below a maximum green density threshold achievable with powder material; b) a die with multiple cavities, and a cavity Providing a pressure tool set, including a pressure piston intended to slide therein; c) placing the preform in the cavity of the die, having a thickness in the millimeter range and 90 Disposing preforms, wherein first and second sintered boron nitride discs having a density of greater than or equal to 10% are respectively disposed within each cavity at a first end and a second end of each preform. D) forming a calibrated compact using a second uniaxial pressing of the preform, said second pressing process being realized with a powder material. Forming a compact in a die using a pressure piston up to a second threshold that is less than or equal to a maximum green density and above a first threshold; and e) temperature, pressure, and duration. Forming a sintered compact by applying pressure and pulsed current to a pressure tool set such that a rapid rise in temperature is produced according to a controlled SPS sintering cycle; and f) removing the sintered compact from the die. And a step of extracting the sintered material pellets. |
