Optimal compositions of chemically resistant silicate composite materials (SCM) based on electrocorundum, which is a waste of the electrometallurgical production of niobium, have been proposed. The chemical composition of electrocorundum is established, X-ray phase, differential thermal analysis is carried out and the results of infrared spectroscopy are presented, an original composition of a ceramic mass based on electrocorundum is proposed, and the physicochemical properties of the obtained SCM are studied. The main characteristics of the material: chemical resistance - up to 99.9%, corrosion rate - 0.5-1 mm / year (resistant), water absorption - 4.4 - 5.4%, thermal resistance - 15-19, compressive strength - 8-16 MPa, shrinkage - 0.1 - 0.6%, abrasion - 0.01 g / cm 2 , adhesion strength - 0.5 - 0.6 Pa. Tab. 5, ill. 4, bibliography: 5 titles.
