2007-9-1 · Effect of attrition milling on sintering conditions. Figure 1(a) shows the mean particle size of BNT and NLT-1 compositions after attrition milling. Every 30 min of milling time, the slurry was taken for particle size measurement. It should be noted that a finer starting particle size (e.g., 1.31 μm of NLT-1 powder) is more resistant to attrition, comparable to a coarser starting particle ...
