Abstract
Prosess og utstyr for å bringe silisiumtetraklorid til å reagere med flytende sink for å fremstille silisium og sinkklorid, der reaksjonen finner sted i en reaktor (1). Silisiumtetrakloridgass sprøytes kontinuerlig inn gjennom en eller flere dyser (7) til en strøm av smeltet sink (5) i en reaksjonssone (2) av reaktoren der temperaturen er over smeltepunktet til sink (>419 ºC) og under koketemperaturen til sinkklorid ved 1 atmosfæres trykk (732 ºC). Reaksjonsproduktene, silisium og sinkklorid, samles i en separasjonssone (3) som de kan tas ut fra. Med den foreliggende nye prosessen og utstyret kan silisium med høy renhet produseres effektivt og billig.
