Steps to make a sample pellet
  • Mixing and grinding chemical powder with an agate mortar or ball mill
  • Calcine mixed the powder in a high temp furnace under a suitable temperature
  • Grinding calcined powder again by mortar
  • Placing the two die inserts in the center hole of the die
  • Put calcined powder into the die inserts
  • Pressing sample by a pressing machine under suitable pressure
  • Take out the pellet sample from the die by easily taking out and opening the split die inserts
  • Sintering the pellet under a suitable temperature (optional)
  • Then, a new material sample is formed

  • Please must always wear protective goggles during operation !!!
  • Please always do the "manual alignment" to avoid any damage under high shear force generated from tilt. 
  • The heating and cooling temperature rate should be below 5 °C/min
  • The volume of feeding material shoud be below 1/3 total volume of Si3N4 sleeve. Over-feeding material may cause damage to the sleeve at high temperature.
  • The pressing die cannot be used for pressing powder with a particle size of < 30 microns. Small particles may slip into the gap between the pushing rod and steel sleeve and cause damages to the sleeve during the compression. Ball mill and sieve the powder and apply only the 32~75 microns powder to the pressing die to avoid damages. Please consider using the 3'' Dia. Sieve Set No.200&450 Mesh to separate the 32~75 microns particles from the powder clumps. Please clean the mold via ethanol after the completion of each experiment. ( Pic. 1)
  • You may use BN coating as mold release (Pic 2)
  • Please use alcohol to clean the pressing die every time before use and store it in a dry place.
