FIELD: chemistry.
SUBSTANCE: invention relates to refractory industry, particularly production of refractory high-strength non-electroconductive articles from corundum and silicon carbide concrete on aluminophosphate binder. Refractory concrete on aluminophosphate binder contains orthophosphoric acid with concentration of 65-75% and a mixture of different fractions of electrocorundum 25A, with the following ratio of components according to FEPA 32GB 1971, wt %: electrocorundum of fraction 20 - 28-36; electrocorundum of fraction 46 - 22-24; electrocorundum of fraction 80 - 15-20; electrocorundum of fraction 220 - 25-35; orthophosphoric acid - 10-12 more than 100%.
EFFECT: high strength, fire-resistance and heat-conductivity, low porosity of articles.
