The benefit of ball milling is its ability to reduce particle size without changing the particle's shape by optimizing the milling time, balltomaterial ratio and milling speed [20]. Since Bi 2 O 3 is a highly brittle metal oxide and significantly susceptible to particle breakage, the ball milling conditions were optimized to obtain particles ...

In the present work, we have investigated the role of calcination temperature in altering the structural, optical and antibacterial properties of ball mill synthesized Co3O4 nanoparticles. The outcomes of Xray diffraction patterns and their Rietveld refinement confirm the presence of spinel cubic phase of Co3O4 and lattice expansion with increase in calcination temperature. The crystallite ...

Lead oxide emissions result from the discharge of air used in the lead oxide production process. A fabric filter is generally used as part of the process/control equipment to capture particulate emissions from lead oxide facilities. Typical airtocloth ratios of fabric filters used for these facilities range from 2:1 to 4:1.
