3. Full Sintering. In a unique watercooled treatment bottle, a whole sintering bar is loaded. The bar will get an electrical current. The heat produced by this current will cause the bar to decrease by around 15% and density to between 85% and 95% of its full density. The bar also starts to produce tungsten crystals. 4.
