Field Assisted Sintering Technology (FAST) , also known as Spark plasma sintering (SPS), or Direct Current Sintering (DCS), is an innovative sintering technique, which has been increasingly used to sinter a variety of materials with nano-sized grains and superior properties.
Dr. Fritsch is the market leader in field assisted sintering (FAST) / SPS / DCS furnaces and presses. More than 1,000 FAST sinter presses have been installed at research universities and companies worldwide. In fact, Dr. Fritsch produces more FAST / SPS / DCS sintering presses per year than all other manufacturers combined!
The main characteristic of Dr. Fritsch FAST press / SPS / DCS furnace is that the continuous high density electric current directly passes through the graphite die, as well as the powder compact, in case of conductive samples. Joule heating has been found to play a dominant role in the densification of powder compacts, which results in achieving near theoretical density at lower sintering temperature compared to conventional sintering techniques. The heat generation is internal, in contrast to the conventional hot pressing, where the heat is provided by external heating elements. This facilitates a very high heating or cooling rate (up to 1000 K/min), hence the sintering process generally is very fast (within a few minutes). The general speed of the process ensures it has the potential of densifying powders with nanosize or nanostructure while avoiding coarsening which accompanies standard densification routes. This has made SPS a good method for preparation of ceramics based on nanoparticles with enhanced physical properties.
