Title:
A way high temperature processing removes an organic pollutant from boron content powder
Document Type and Number:
Japanese Patent JP6148469
Kind Code:
B2
Abstract:
Methods for removing an organic contaminant from contaminated boron powder include providing a contaminated boron powder, the boron powder being comingled with an organic contaminant. The method also includes placing the contaminated boron powder onto an inert container and placing the inert container and the contaminated boron powder into an enclosed space. The enclosed space environment is altered to create an oxygen deficient atmosphere. A heat source is provided to heat the contaminated boron powder to an elevated temperature. The method includes vaporizing the organic contaminant so as to reduce the amount of the organic contaminant comingled with the boron powder. Another method includes reducing the amount of the organic contaminant comingled with the boron powder to not more than about 0.1 weight percent of soluble residue.
