1. Hot pressing is mainly used to fabricate hard and brittle materials.2. Another common term is " Rapid Hot Pressing ( RHP ) ". 3. In direct hot pressing , the mold is directly connected to electrical power. 4. With direct hot pressing technology, materials can be sintered to their final density. 5. Of particular concern was whether they would use casting or hot pressing with the explosives. 6. Hot pressing provides higher density material.7. To produce the first pits, hot pressing was used to optimally employ the scarce plutonium. 8. This avoids density variations in the final component, which occurs with more traditional hot pressing methods. 9. After hot pressing or cold pressing, sintering, and arc grinding, diamond segments are formed. 10. Possible fabrication methods include Czochralski and floating zone for single crystals and hot pressing and sintering for polycrystalline.
