Aluminium Fluoride - Entrepreneur India

There are two main ways to produce aluminium fluoride. One production process is called the "dry process" in which aluminium fluoride is produced from fluorspar (CaF2) and results in a quality referred to as "high density" aluminium fluoride. High density quality consists of 90-92% of aluminium fluoride.
