FIELD: manufacture of refractory materials of corundum composition; manufacture of articles for lining of different thermal units working at high temperatures.
SUBSTANCE: charge includes synthetic corundum modified with readily decomposing additive of aluminate composition (for example, aluminum nitrate, aluminum formiate, bauxite, etc.) in the amount of 1-5 mass-% and phosphate binder. Used as phosphate binder is aluminum-boro-phosphate binder at the following composition of components, mass-%: modified corundum, 90-93 and phosphate binder, 7-10. Proposed charge makes it possible to reduce its sintering temperature and porosity of articles at enhanced strength and heat resistance and additional residual change in sizes at heating (by 1-13%).
EFFECT: enhanced efficiency.
