Recycling of Shale Coke with Liquid Glasses to Produce Heat Insulation

On the basis of shale coke and liquid glass, a porous filler (heat insulation) with thermal conductivity no more than 0.25 W/m °C may be produced. M350 filler is made by adding 70% shale coke to the liquid glass; that composition is optimal. Research shows that, for a sample of optimal composition, the porosity is less evident on the exterior than in the interior. Observations reveal that the internal structure of the sample consists mainly of closed pores, which result in stronger components than open pores.
