摘要：To investigate the quantitative relationship between ionic potential and coal ash fusibility, the chemical compositions and ash fusion temperatures (AFTs) of 214 coal ashes were tested. The prediction models of AFTs with the metal ionic potential concentration (CMP= n-ary sumation wi*ziMi*ri n-ary sumation wi/Mi) were established by linear fitting. The mineral evolution under different C-MP was calculated by FactSage 7.2. and was used to reveal the effect mechanism of C-MP on AFTs. The results showed that AFTs initially emerged a negative correlation (24.13 nm(-1)
