摘要：

In this study, lightweight thermal insulation materials were successfully prepared in this study using a high-temperature micro-foaming method at 1200 degrees C, where granite waste was the main raw material and SiC was the foaming agent. Further, the thermal insulation material's macrostructure, microstructure, room temperature, and high-temperature performance have been investigated. This material has a small closed-cell porosity of up to 73.8%, high compressive strength of 18.2 MPa, low thermal conductivity of 0.22 W/(m.K) at room temperature and 0.17 W/(m.K) at 350 degrees C, positive reheating linear change, and the refractoriness under load of 812 degrees C, confirming that these materials can be used as good thermal insulation materials up to similar to 800 degrees C.
