The volatilization of mould powder concludes the evaporation of alkali oxides besides the evaporable fluoride created between the fluorine and acid and alkali oxides. The results of CaO-SiO〓-Na〓O ternary fluorine free slag are: there is a strong relationship between volatilization of Na〓O and basicity R.

对CaO-SiO〓-Na〓O三元无氟渣系的测定结果表明，渣中Na〓O的挥发与碱度R有很大关系，当R＜1时，单位时间内其挥发百分率是恒定的，且受温度的影响不大；当R＞1时，单位时间内的挥发百分率将随其含量的增加而增加。
