Title:
METHOD OF MANUFACTURING METAL SILICON
Document Type and Number:
Japanese Patent JP2011006316
Kind Code:
A
Abstract:
To provide a method of efficiently manufacturing metal silicon using a silicicolous plant such as rice husks.
The method of manufacturing metal silicon has a step of: forming silica ash containing mainly silica by firing the silicicolous plant; and a step of: adding aluminum into the resultant silica ash and heating it under an inert gas atmosphere to cause a reaction of formula: 4Al+3SiO2→3Si+2Al2O3 to obtain the metal silicon.
