With the rapid development of the ferronickel smelting industry, the ferronickel slag has become the fourth largest industrial slag in China, in urgent need of efficient treatment. In this study, a facile route for preparing insulating materials from ferronickel slag with the addition of fly ash cenosphere was developed based on thermodynamic calculation and experimental exploration. The experimental results showed that a high-quality insulating material with thermal conductivity of 0.4752 W/(m. K), bulk density of 1.36 g/cm3, and compressive strength of 34 MPa could be obtained when the ferronickel slag was sintered with addition of 25 wt % fly ash cenosphere at 1200 °C for 2 h. The method is expected to provide a useful guide for treatment of ferronickel slag.
