Baco 3 nanoparticles are demonstrated as outstanding electrocatalysts to enhance the high temperature oxygen reduction reaction (orr) in solid oxide fuel cells (sofcs). In my past life of chrome plating, i would periodically have to add both sulfate and barium carbonate. we operated a mixed catalyst bath. to raise sulfate .02 oz/gal i added 200 ml sulfuric / 1000 gal solution. to lower sulfate .02 i added 7 lbs barium carbonate. this is done on off shift, lightly sprinkled over surface of tanks with scrubber ... High quality barium carbonate manufacturers price baco3 cas:513-77-9 , find complete details about high quality barium carbonate manufacturers price baco3 cas:513-77-9,baco3,baco3 cas:513-77-9,price baco3 cas:513-77-9 from carbonate supplier or manufacturer-luoyang lida chemical co., ltd. At the carburizing temperature (940˚c), p 2 is much higher than p 1, hence, barium carbonate can only exist in the form of baco 3, barium oxide can't appear, the decomposition-generation cyclic reaction is never to take place. if, in accordance with the crmm, the barium carbonate should be inactive, but it is actually a good catalyst.
