<p>The method provides for thermal treatment of an exothermic mixture in a burning regime and subjecting the resulting solid products to the influence of external forces directed tangentially and/or perpendicularly to their surface at a temperature from around or below their burning point up to 0.5 of their melting point with subsequent extraction of the obtained powdered refractory material. The reactor comprises a casing (1) with a reaction cavity (8) inside which are mounted a device (11) for feeding into it on exothermic mixture under pressure and a rotor (9) with a tip (10), both being connected to the cavity (8). The external surface of the tip (10) forms, together with the internal surface of the casing (1), an annular gap (12) for removing the powder refractory material.</p> |
