摘要
密度是重要的熔体结构敏感物性之一。纯Bi熔体的密度-温度曲线表明,随着温度的升高,密度值先升高,而后不均匀下降,在高出熔点34℃左右(大概在315℃处)密度出现最大值10．002 g·cm-3。Bi熔体密度的异常变化点与粘度异常变化点基本一致,且与DSC曲线上热效应峰基本对应。
Density is one of the most important sensitive physical properties of melt structure. The density-temperature curve of Bi melt showed that the density values increased firstly and then dropped non-homogeneously with the increase of temperature. At about 34℃ above the melting point （about 315℃） ,the density has the maximum value around 10.002g·cm^-3. The abnormal points of the density are in concordance with the ones of viscosity and thermopeaks on the DSC curve.
