Abstract

Framgangsmåte for å selektere silisium-metalloid av kjemisk kvalitet som har en forbedret ytelse i den direkte framgangsmåten for å framstille organohalosilaner, hvorved organohalidet blir reagert med silisium-metalloid i nærvær av en kobber-katalysator ved forhøyet temperatur. Framgangsmåten omfatter måling av temperaturen i en batch silisium-metalloid både under foredling og støping av silisium-metalloidet; og måling av nivåene av element-urenheter i batchen av silisium-metalloid. Deretter omfatter framgangsmåten forutsigelse av egenskapene av slagget som dannes under foredlingen silisium-metalloidet, basert på likevekts-beregninger ved bruk av nivåene av element-urenheter og de målte temperaturene i batchen av silisium-metalloid. Endelig omfatter framgangsmåten seleksjon av et silisium-metalloid for bruk i den direkte framgangsmåten for å framstille organohalosilaner, basert på de forutsagte slagg-egenskapene, slik at slagg-tetthet, viskositet og smeltepunkt av slagget er innen aksepterbare og forhandsbestemte områder for batchen.
