Die-GP-12 graphite die is good for dry pellet pressing ceramic material at high temperature up to 2000 ºC.

SPECIFICATIONS:

Model	Die-GP-12
Whole set pressing die includes	One 0.5"(12.7mm) I.D. core die made of high purity & high strength graphite One sleeve for core dies protection Two pushing rods are highly polished to ensure a perfect fit in the die. One pressing pole for releasing the sample from the die only. Max. Working temperature: < 399ºC in air > 400 ºC needs inert gas protection Max. sustainable pressure is 100 MPa (~1.2 ton force applied on the die) The die is specifically designed for our Compact Hot Pellet Press to meet the high-temperature requirement
Steps to make a sample pellet	Mixing and grinding chemical powder in an agate mortar or ball mill Calcine mixed the powder in a high-temperature furnace at a suitable temperature Grinding the calcined powder again in a mortar Put the calcined powder into the die Pressing a sample by a pressing machine under suitable pressure Take out a pellet sample from die Sintering the pellet under suitable temperature Then, a new material sample is formed!
