The paper explains the necessity and basic principles of fabricating slag glass‐ceramic based on special local antimony‐containing slag. A CaO‐Al 2 O 3 ‐SiO 2 three‐component phase diagram was used to plan a base glass composition, to which four selected nucleating agents, Cr 2 O 3 , ZrO 2 , P 2 O 5 , and TiO 2 , were added separately. Studies focused on their roles in the crystallization of the present slag glass system with the aid of differential thermal analysis, X‐ray diffractometery, and scanning electron microscopy. Comparisons showed that the four nucleating agents behaved differently and therefore exerted different influences on crystallization. TiO 2 proved to be the best one, and its optimal concentration was 10 wt%.
