PROCEDURE FOR PRODUCTION OF SILICON CONTAINING ELEMENT FOR PREPARATION OF SILICON CONTAINING ALLOYS Russian patent published in 2010 - IPC C22C21/00 C22B5/04 

FIELD: metallurgy.

SUBSTANCE: procedure consists in mixing crushed crystal silicon with halogenides containing flux. Also one or multi-element flux is used as halogenides containing flux; it contains complex halogenides of the alloying element, while crushed crystal silicon has dimension of fractions smaller, than 10 mm. Further produced mixture is heated at rate 30-70°C/min to temperature not below temperature of flux aggregate state change. The mixture is heated to the temperature no more than 1.03 of flux melted temperature or no more than 1.05 of flux melted temperature in the beginning. Notably, reagent is produced in form of particles of silicon tied with melted flux. Further it is cooled to solidification.

EFFECT: reduced losses of aluminium and silicon and reduced losses of flux.
