PTFE being matrix and graphite being filler so mixture of 27 grams were taken and compacted with compression load of 50kn .?compacted into cylinder shape?
so what sintering temperature should be applied.
Specify the type of sintering you intend to do. Pressureless? Hot pressing? SPS? HIP?
Would it be solid-phase sintering or liquid-phase sintering?
And what is the composition of the mixture?
initially powders (95% PTFE and 5% gr ) were compacted at a pressure of 40KN, then those compacted ones has to be sintered.
Dear Prajna Deepthi ,
you need to perform a thermodilatometry analysis to evalute the sintering rate and the sintering shrinkage. This paper in attachment can hel you.
Good luck

PTFE is a polymer, Graphite is refractory, sintering maybe an incorrect terms. For a polymer maybe you intent some kind of curing and polymerisation and in this case the temperature is governed by the glass transition temperature of the matrix. However, my opinion is that there is no interaction to be expected between PTFE and graphite so the real problem is the dispersion of the two powders....
@Mr Domenico : graphite coated with copper will be added as a filler.
Kindly clarify
