Use of Byproducts of Acidic Processing of Aluminium – Bearing Raw Materials in Production of Heat Insulating Materials

The principal possibility to use byproducts of acidic processing of aluminium-bearing raw materials as the main component of batch to obtain a heat insulating material using low-temperature technology is established. The compositions suitable to obtain low-temperature frit and a foam glass material on its basis are developed. The obtained material has improved physical – mechanical properties in comparison with conventional foam glass from broken glass.
