Abstract
The principles of the choice of compositions applicable for the low-temperature granulate production lay the foundation of physicochemical modeling of the composition of foam glass-crystal material in Na2O-CaO-SiO2 and Na2O-Al2O3-SiO2 systems. The model composition of granulate should provide the amount of melt formed at the temperatures below 950°C, at least 75%. The amount of crystalline phase in granulate should not exceed 20%; this provides the viscosity of the system in the foaming range (800–850°C) at 103–106 Pa s. To achieve the given viscosity of melt, the foaming temperature should be increased up to 950°C. During the formation of the nanosized crystalline phase in interpore partition, the strength of the material amounts to 3 MPa. In the course of the foaming process of the crystallizing granulate, the amount of the crystalline phase achieves 50%; this provides the strength of the foam material up to 10 MPa.
