Abstract

PURPOSE: To control the corrosiveness of a fluorine-contg. soln. by adding aluminum ions or silicon ions of a specified concn. to the soln.
CONSTITUTION: To a fluorine-contg. soln. are added aluminum ions and/ or silicon ions in an amt. above 1/6 equivalent of fluorine in the form of salt, oxide or element. Thus, corrosion of a container, an apparatus, etc. due to the soln. is prevented. Aluminum sulfate is esp. preferable.
