by ball-milling calcination. The sam-ples were characterized by TG, XRD, TEM, XPS, FT-IR, DRS, EIS, Photocurrent and Photoluminescence meas-urements. Photocatalytic performance of the catalyst was measured by the degradation test of methyl orange (MO). The photocatalytic performance of In 2 O 3 /C 3 N 4 compos- ites is higher than that of In 2 O 3 and C 3 N 4

Influence of Ball-milling on Sintered Body Density of Fine

The fine pure tungsten powder with a BET particle size of 0.14 μm was prepared by sol spray drying-calcination-hydrogen reduction process. The influences of ball-milling ways (dry-milling and wet-milling) on the tungsten powder morphology and powder formability were investigated. The changes of pure tungsten properties with sample size (small samples with a thickness of 2.5mm and big samples

The calcination temperature showed a remarkable effect on the formation of magnesium aluminate spinel in both ball milling and co-precipitation methods. Compared to the ball milling method, the co-precipitation method showed several advantages. By employing the ball milling method, peaks corresponding to MgAl 2 O 4 spinel started to appear at
