| Abstract: | Some problems of the Na2O content measurement are discussed in reclaiming ed sand bonded with sodium sillcate and a good measuring method of Na2O content is recommended. The relation between the ratio of remainbinder film shedded by reclaimer and the measuring precision of Na2O content has be stated simply by analyzing the factorsof affecting Na2O content measuring Precision. |
