The main mineral composition of nickel slag is 2MgO·SiO 2, FeO·SiO 2 and MgO·SiO 2. Nickel slag powder is obtained by grinding the crushed nickel slag through a test mill for 15 minutes and then passing it through a 200mesh sieve. In this paper, ultrafine powder of nickel slag was used, the specific surface area of which was 450 m 2 /kg.
