摘要：
A model for thermal composition of CaCO3 in Na2B4O7 molten slag is presented in the paper. The experimental results show that the size of CaCO3 particle and CaO content in slag have effect on foaming by gas inside the slag, and these effects are all dependent on the decomposition behavior of CaCO3 in molten slag. Therefore, the foaming index, Sigma, which is measured with bubbling, cannot be employed to evaluate the stability of foams from gas inside the slag.
