METHOD OF PREPARING REFRACTORY COMPOUNDS AND MATERIALS BASED ON THESE COMPOUNDS Russian patent published in 1998 - IPC

FIELD: refractory materials. SUBSTANCE: exothermic mixture of principal components and heat-releasing additives is prepared. Working medium is manufactured in the form of loose material or compressed briquet, reaction of burning is initiated, and combustion products are removed directly during the burning process by way of using, as additives, explosive nitro compounds producing gaseous combustion products in amount adequate to exclude burning-to- detonation transition. EFFECT: increased exothermic capacity of reactions leading to formation of refractory compounds and thereby improved quality of materials made on their basis.
