摘要：

The effect of fluorine content on the sinterability and crystallisation of glass belonging to CaO-Al2O3-SiO2 system was investigated. It was shown that increasing fluorine content promotes sinterability and crystallisation simultaneously. The Avrami exponent and activation energy for crystallisation of the most promising specimen were determined according to the Marotta method. The calculated Avrami exponent confirms a surface crystallisation mechanism. Results in the present paper suggest that with increasing fluorine content, the sinterability, crystallisation and mechanical properties of the system are improved whereas the chemical resistance is degraded.
