Document Type and Number:
Japanese Patent JP2013028515
Kind Code:
A
Abstract:
To provide a method for removing boron from metal silicon at high speed.
In this method for removing boron from metal silicon, a metal silicon porous body containing boron is irradiated with plasma and melted, and then cooled under a non-oxidizing atmosphere. Preferably, the metal silicon porous body has a packing factor of ≥60%, or is prepared by sintering metal silicon powder under a reducing gas atmosphere, or is prepared by sintering metal silicon powder at ≥800°C.
