Aluminium Fluoride — A Users Guide

  • Stephen J. Lindsay

Abstract

Aluminum fluoride is an important raw material that is primarily manufactured via reactions of aluminum tri-hydrate either with fluorspar or with fluosilicic acid. Impurities generally have a minor impact upon smelting processes and metal products, but there can be exceptions. Likewise there are some physical properties of concern with this raw material. In this paper the author illustrates the important factors to consider when selecting and using sources of AlF3.
