Abstract :
The paper describes the foam-glass crystal material production technology via the intermediate product comprising residual crystalline phase. Different factors impact (macroscopic structure, quantity and size of the crystalline phase) on the foam material strength properties has been searched. It has been stated that the material with a hexagonal shape of pores 1-1.5 mm in size and partitions 40-50 μm thick is characterized by the maximum strength. When nanospheroids are formed in the noncrystalline matrix of the foamed material partition, its strength reaches 4.5 MPa which is close to the values of calculated strength (5 MPa).
