METHOD AND APPARATUS FOR PREPARING REFRACTORY INORGANIC COMPOUNDS Russian patent published in 1997 - IPC

FIELD: powder metallurgy. SUBSTANCE: in a method provided, self- propagating high-temperature synthesis is involved. Preliminarily shaped blend is put into reactor to form a charge with through channels, after which combustion reaction is initiated followed by synthesizing and cooling synthesis products by way of blowing gaseous cooling agent through channels on condition that ratio of summary surface area of cross-section of through channels in blend charge to that of cross-section of blend charge is at least 0.13. apparatus suitable to implement method is also provided. EFFECT: intensified process. 7 cl, 3 dwg, 2 tbl
