“My opinion to avoid the broken of the pellet during the sintering process you have to remove PVA to avoid the burning of the pellets by heated the pellet till 500oC with a heating rate of 2oC/min. Then you have to start the sintering process with slow heating rate by this way the pellet will not break”. View · Muhammad Shoaib.
