GB/T 3653.1-1988 Determination of boron content in focused ferroboron, using the Titrimetric method of alkali content. The standard is clearly applicable to ferroboron samples, and describes the principle of titration for the determination of boron content after the reaction of alkali and boron. Specify the equipment required for the experiment, such as Burette, etc., as well as various reagents. Detail the pre-processing steps of ferroboron samples, such as the dissolve method, followed by the titration operation process, including indicator selection, titration process control, etc. According to this standard, the boron content in ferroboron can be accurately determined, providing key data support for the mass control of ferroboron and production applications, and assisting the production and mass evaluation of related industries.
