To prevent reactions between carbon and the other starting powders, the ceramics should be sintered at a lower temperature within a very short time. In the chapter, a Si 3 N 4 /C nano/nano‐composite is prepared for the first time through high‐energy ball milling, followed by spark plasma sintering. The chapter also discusses in detail the ...
to the nano level was carried out using a highenergy planetary ball mill (Pulverisette, Fritsch, Germany). The total duration of milling was 60 hours. The following milling conditions were maintained: loading of the ball mill with 10:1 ratio of balls to fly ash and milling chamber and balls were of tungsten carbide, the ball diameter was
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter (Figure ).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
