What is BS 3907-8 – Magnesium and magnesium alloys about?
BS 3907-8 standard is a part of the BS 3907 series that discusses the determination of total rare earths using the gravimetric method for the analysis of magnesium and magnesium alloys. The advantage of magnesium alloys to be used in such applications is their lightweight, high strength-to-weight ratio, high stiffness-to-weight ratio, castability, machinability, and great damping.
Who is BS 3907-8 – Magnesium and magnesium alloys for?
BS 3907-8 on magnesium alloys applies to:
- Manufacturer of magnesium products
- Quality testing personnel
- Aerospace industries
- Designing engineers
Why should you use BS 3907-8 – Magnesium and magnesium alloys?
Rare-earth elements (REE) are necessary components of more than 200 products across a wide range of applications, especially high-tech consumer products, such as cellular telephones, computer hard drives, electric and hybrid vehicles, flat-screen monitors and televisions. Gravimetric analysis, is a method of quantitative chemical analysis in which the constituent sought is converted into a substance (of known composition) that can be separated from the sample and weighed.
BS 3907-8 provides you with the principle of total rare earth using the gravimetric method in which the sample is dissolved in hydrochloric acid. Zirconium is precipitated with ammonia and filtered off. Rare earth is separated from the filtrate in the form of sebacate. The precipitate is redissolved and the rare earth is precipitated as oxalates, ignited and weighed as rare earth oxides. The method is suitable for rare earth content between 0.2 and 10 %.
With obedience and compliance to BS 3907-8, you can efficiently manufacture high-quality magnesium alloys using the determination of total rare earth elements using the gravimetric method.
