Procedure

Barium sulfate nanoparticles are prepared according to the teaching of Chemical Engineering Journal 149 (2009) 473-478. 100 g barium sulfate suspension (10 wt % barium sulfate) is mixed with 300 g carbon black suspension (10 wt % carbon) and 600 g water. The combined mixture is sheared for 15-20 minutes until the components are intimately mixed. The feed is then pumped to an atomization unit to form droplets and the droplets are entrained in a gas stream and sprayed into spray conversion equipment such as a spray dryer. The spray dryer is operated with an inlet temperature of 550° C. and an outlet temperature of 300° C. to produce composite particles of carbon black/barium sulfate (75:25 by weight).
