| Abstract: | A microwave oven is used for drying the BaSO4 precipitate which has been filtered off on a sintered glass filter crucible. Only 6 min is required for the heating, without any preheating of the oven. The results compare favorably with those obtained from the traditional ignition of precipitate in paper. |
