Abstract
A method for sintering includes loading a tool material into a resistance heating element within a HPHT press and heating the resistance heating element at a first axial portion to a control temperature, where a temperature difference is measured between the control temperature and a second temperature measured at a distal axial portion along the resistance heating element, wherein a difference between the control temperature and the second temperature ranges between about 5 percent to about 11 percent of the control temperature.
