The foaming behavior was investigated by means of injecting Ar and decomposing CaCO3 respectively. The foaming index Σ in the case of injecting Ar changes a little bit, but the values calculated with viscosity, density and surface tension have large deviation. With the average foaming life ,the foaming behavior of the melt in the decomposing CaCO3 could be described rationally, while in this case the foaming index Σ can not be applied to indicate the complicated measurement result. Key words:  Ca-Na2B4O7 melt      decomposition      average foaming life      foaming index      Received:  18 August 1998      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1998/V34/I8/875 1 Kozakevitch, P.
