Increasing the absorption ability of electromagnetic waves by using the graphite and silicon carbide (SiC) crucible coated with a thin layer of yttrium oxide (Y2O3) was obtained in the experimental process of expanding the recycled residual glass for cellular glassceramic making without affecting the physical, thermal, mechanical, and microstructural features compared to products made by known conventional or unconventional techniques. The heating rate reached very high values (between 25.5-31.5 °C/min) compared to the known techniques without affecting the microstructural homogeneity of specimens. The features of material that give it excellent thermal insulation properties for possible using as a building material (density between 0.23-0.33 g·cm-3, heat conductivity between 0.036-0.049 W·m-1·K-1, porosity between 84.3-89.1 %, compressive strength between 1.28-1.52 MPa, and water absorption under 1.6 vol. %) have not changed compared to the products usually manufactured in the world by conventional methods.
